Answer:
The climate in that area is different today then when tropical plants and animals lived there
Explanation:
The climate on Earth is constantly changing, and there's numerous factors that contribute to it. The climate can shift from being warm and wet, to cold and dry relatively quickly, thus changing the flora, fauna, and the landscape as a whole. It is no wonder that tropical plants and animals are found in the fossil records in the northern part of Texas, as in the past this region has been dominated by warm and wet climate. That enabled the development of a biome that supported tropical plants and animals. That didn't lasted forever of course, and the climate changed, so Texas became a place with more temperate climate with relatively small amount of precipitation, resulting in changes of what types of animals and plants live there.
Answer is option c) The climate in that area is different today than when tropical plants and animals lived there.
The most likely cause for the disappearance of tropical plants and animals in North Texas is significant changes in the climate over time.
Fossils of tropical plants and animals found in limestone rock in North Texas indicate that the climate in this area was once much warmer and more tropical. The most likely cause of the disappearance of these plants and animals is that the climate in that area is different today than when tropical plants and animals lived there. Over geological time scales, changes in the Earth's climate have transformed regions, leading species that could not adapt to new conditions to either migrate or go extinct.
For example, scientists have observed major climatic shifts in regions like the Olorgesailie region in Kenya. These shifts have caused some species to go extinct and allowed new, more adaptable species to thrive.
Birds that do not receive adequate nutrition during development sing less often and for shorter periods of time as adult birds. Which BEST describes the outcome of nutritional stress in these songbirds?
They are less likely to obtain good nesting sites.
They are less likely to attract mates and pass on their genes.
They are less likely to find adequate food supplies.
They are less likely to ward off predators.
Answer: i believe it is b, they are less likely to mate
Answer:
They are less likely to attract mates and pass on their genes.
Explanation:
The singing of birds uses a lot of energy from their bodies, for this reason, birds that do not eat properly tend to sing less often to save the little energy they have. However, birds only sing when they have motives and the main reason for this song is to attract reproductive partners for mating. With this, we can conclude that if the bird does not eat well, it will have little energy and will not have frequent frequency, so it will be less likely to attract partners and transmit its genes.
Throughout the year, these animals sing more in the spring. This period is the breeding season for birds, who wish to demarcate territory and attract females. In the following season, the summer, the chicks are born, and the singing decreases. In addition to not wanting to attract unwanted visitors to the nest, both the male and the female are totally focused on raising the young.

What is the synthesis of proteins in an animal cell
Answer:
The building blocks of proteins are amino acids. - The sequences of nucleotides/bases in DNA provide a genetic code for the sequence of amino acid connections, which form protein molecules.
Explanation:
Final answer:
Protein synthesis in animal cells is a critical energy-consuming process where ribosomes translate mRNA messages into polypeptide chains that fold into functional proteins. These proteins contribute immensely to cellular structure and function. The process is highly regulated and involves the mRNA template, ribosomes, tRNAs, and enzymatic factors.
Explanation:
Protein synthesis is a crucial process in animal cells that consumes more energy than any other metabolic activity. Proteins are essential for the structure, function, and regulation of the body's tissues and organs, and therefore constitute a significant portion of cellular mass, second only to water. The translation process involves decoding an mRNA message into a polypeptide chain, which eventually folds into a functional protein. This assembly is facilitated by ribosomes, which catalyze the formation of peptide bonds between amino acids, resulting in polypeptide chains that can range in size from around 50 to over 1,000 amino acids. These polypeptides undergo post-translational modifications before becoming fully functional proteins capable of performing a plethora of cellular functions.
The machinery involved in protein synthesis includes not just the mRNA template but also ribosomes, transfer RNA (tRNA), and various enzymatic factors. Each amino acid added to the growing polypeptide chain is selected by tRNA molecules that match the corresponding codon on the mRNA. This ensures that the sequence of the resulting protein is exactly as encoded by the gene. The process is highly regulated at the transcriptional and translational levels, ensuring that proteins are synthesized as needed by the cell.

Small animals like rodents, lizards, birds, snakes, frogs are common in this forest. Tall tress are used as shelter and also as source of food.
The tropical rainforest is the habitat known for a wide range of animals including birds, monkeys, snakes, and insects. This biodiversity-rich environment supports numerous species. The canopy is particularly important for bird species.
The habitat that is known for many species of birds, monkeys, snakes, lizards, frogs, and insects is the tropical rainforest. Tropical rainforests are incredibly biodiverse. They are home to a wide range of animals including numerous insect species, small mammals like bushpigs and bushbucks, and larger mammals such as monkeys and leopards. The canopy of the rainforest provides a perfect habitat for birds such as pigeons, eagles, and the Knysna Loeries.
Protists aren't monophyletic, meaning that they don't
A. share one common ancestor that isn't also shared by organisms in other groups.
B. have one mode of reproduction.
C. have one chromosome.
D. live their lifespan in one place but instead can move.
Answer:
A. They don’t share ancestors with other organism in the same grouping. Protists belong in a paraphyletic group
Answer:
A. share one common ancestor that isn't also shared by organisms in other groups.
Explanation:
A monophyletic group includes all the descendants of an ancestral species. On the other hand, a paraphyletic group includes some descendants of a common ancestor. Protists are not monophyletic as they share a common ancestor with other groups. Hence, protists are said to be paraphyletic. Mammals are monophyletic as all the mammals share a common ancestor which is not shared by organisms of any other groups.

does a horse and dolphin have the most shared derived characteristics?
Answer:
no
Explanation:
because there Gene's are totally diffrent
Final answer:
Phylogenetic trees show that dolphins do not share the most derived characteristics with horses. Instead, they have a common ancestry with even-toed ungulates. The similar body shapes between dolphins and fish are an example of analogous traits due to convergent evolution.
Explanation:
In biology, phylogenetic trees are used to show the evolutionary relationships between different species. These relationships are determined through various evolutionary characteristics which can either be shared or derived. Regarding the relationship among different animals, let's address the questions raised by examining their evolutionary traits.
When considering the evolution of cetaceans, which includes dolphins, we observe that they have derived from even-toed ungulates and share a common ancestry with several other mammals including the hippopotamus, cow, sheep, camel, and pig. This common ancestry indicates that a horse, which is also an ungulate, is not the closest relative to a dolphin within this context. An armadillo would not fall on the same branch of the phylogenetic tree close to horses or cetaceans.
Comparing DNA sequences among animals, a whale would share more sequences with a horse than with a shark because whales and horses are both mammals; whereas, sharks are fish with a very different evolutionary history. Lastly, the similar body shape observed between dolphins and fish is an example of an analogous trait, since dolphins are mammals and fish are not, their similar body shapes have evolved independently due to convergent evolution within similar environments.
How many electrons are in this atom?
B there is 7 electrons
An atom of nitrogen has (B) seven electrons.
In an atom in neutral state, number of electrons are equal to the number of protons. Since nitrogen has an atomic number of 7, which indicates the number of protons in its nucleus, it also has seven electrons to balance the positive charge of the protons and maintain an overall neutral charge.
Electrons are subatomic particles carrying a negative electrical charge. It is one of the fundamental particles that make up atoms, along with the protons as well as the neutrons. Electrons are a part of the family of elementary particles known as leptons. The movement of electrons within materials is responsible for electrical current flow and the generation of electromagnetic fields.

Which could describe the motion of an object?
Answer:
Distance=10 meters and displacement=10 meters
Explanation:
Did the quiz
When an object is moving, it has a velocity, which includes both speed and direction.
The simplest motion to describe is one-dimensional motion, such as a train on a straight track. Knowing the object's position as a function of time is crucial for understanding its motion.
When an object is moving, it has a velocity. Velocity is the rate of change of the position of an object. It includes both the speed of the object and the direction in which it is moving. In contrast, speed describes only how fast an object is moving, not the direction. For instance, a car traveling north at 60 km/h has a different velocity than the same car traveling south at 60 km/h, even though the speed is the same in both cases. The simplest motion to describe is one-dimensional motion, like a train moving along a straight track. To accurately describe this motion, we need to know the object's position as a function of time, labeled as x(t). Understanding concepts like kinematics is essential for accurately analyzing motion in physics.

How does the immune system work together with the circulatory system to function properly?
A.
The circulatory system's arteries cause the immune system to work harder by bringing oxygen-depleted blood to the infection site.
B.
Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.
C.
White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.
D.
The immune system's red blood cells fight and destroy foreign antigens.
Question Resources
The immune system functions in conjunction with the circulatory system by having white blood cells travel through blood vessels to areas where they are needed to destroy pathogens. Therefore, the correct option is C.
Explanation:The immune system and the circulatory system work together intricately to maintain body health. White blood cells (leukocytes), including monocytes and lymphocytes, are a crucial part of the immune system. These cells travel throughout the body via the blood and lymphatic systems as part of the circulatory system to detect and fight pathogens. The correct choice that describes how these two systems collaborate is:
C. White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.
The circulatory system also transports nutrients that are vital for the immune system's proper functioning and aids in removing waste products created by the immune system during the fight against invaders.
15. A geologist discovers a sample of fine-grained rock made up of very small crystals. Based on its physical appearance, what can the geologist conclude about the rock?
Answer:
It is an extrusive igneous rock
Explanation:
Based on the physical appearance, the geologist can make an accurate conclusion about the rock's formation and in which type of rocks does it belong. The fine-grains made up of small crystals give away clues about the formation of the rock. Fine grains with small structures occur when the lava reaches the surface and cools off very quickly, thus not giving the crystals enough time to grow, so they are very small. The geologist can classify this rock on base of this information as an igneous rock, as it has been formed from lava, and as an extrusive igneous rock, as the fine grains and small crystals only occur when the lava cools of quickly on the surface.
Answer:
It formed from rock that cooled quickly

How would seasons on Earth differ if Earth's axis was at a 90 degree angle relative to its orbit?
Seasons on Earth would not be affected.
The entire planet would experience the same season at any given time.
There would be no seasons anywhere on Earth.
It would always be summer at the equators and winter at the poles.
Answer:
There would be no seasons anywhere on Earth
Explanation:
If the Earth's axis was not tilting and it was at a 90 degrees angle relative to its orbit, then the seasons on Earth would disappear. The climate on the planet would be defined by the latitude. The equator and the areas close to it would always have summer, as they will receive direct sunlight throughout all of the year. The mid-latitudes will always have temperate climate, reminding of spring and autumn, as the sunlight will not be very direct, but it will also not be very dispersed, jut enough to create a constantly pleasant climate. The higher latitudes will always have winter, as the sunlight will come at a very low angle throughout all of the year, thus it will be very dispersed, not enough to ever warm this parts enough, so they will constantly be under ice.
Answer:
The entire planet would experience the same season at any given time.
Explanation:
Due to the tilt, some parts of the earth will be tilted towards the earth at a particular point in the orbit while others will be tilted away from the sun. This means the amount of sunlight reaching these points is differential. This also changes dynamically, more pronounced in the poles, as the earth revolves around the sun. Without the tilt, this phenomenon would not be therefore and there would be no changes as the earth revolves around the sun.

Answer:
Density independent.
Explanation:
Density independent factors refer to the limiting factors that affect the population is the same way regardless of the size of the population. It could be natural disasters, unusual weather and human activities such as clear cutting forests.
Answer:
Density independent
Explanation:
The limiting factor shown in the question above is independent of deity.
The term density-independent limiting factor is used in ecology, along with the deity-dependent factor to describe growth-limiting factors in a population. When a factor causes changes in the birth and death rates of a population it means that it is a density dependent factor, since it interferes with the population density.
However, when population mortality and birth rates are modified without changing the size of the population, the density of that population is not modified and this is an density independent factor.
Three bases found on mRNA are called a?
Answer: Codons
Explanation:
The mRNA bases are grouped into sets of three, called codons. UAG is amber, UGA is opal (sometimes also called umber), and UAA is ochre. Stop codons are also called "termination" or "nonsense" codons.
Three bases found on mRNA, referred to as a codon, correspond to a particular amino acid, encoding the genetic information that is translated into a protein sequence.
Explanation:Three bases found on mRNA are indeed referred to as a codon. The cellular process of transcription generates a strand of messenger RNA (mRNA), a copy of one or more genes within the DNA. This copy is composed of sequences, A, C, G, and U (uracil). Each triplet of bases, or codon, on the mRNA corresponds to a particular amino acid. In other words, the genetic code is a series of codons, and this code is translated into a protein sequence through the process of translation.

pharynx
trachea
bronchi
nasal cavity
larynx
Answer
Nasal cavity
Larynx
Pharynx
Trachea
Bronchi
Answer:
Nasal cavity, pharynx, larynx, trachea and bronchi.
Explanation:
Respiration may be defined as the process of the exchange of gases between the external environment, lungs and tissues. Oxygen is inhaled in and carbon dioxide is exhaled out from the body.
The first passage way of oxygen is the nasal cavity. From the nasal cavity, the air is passed to the pharynx. Pharynx is also known as the throat of the body. From the pharynx, the air is passed to the layrnx. Larynx is the voice box. The air is then passed to the trachea or the wind pipe. From the trachea, the air is passed into the lungs that contains the small branches called bronchi. From brochi to the alveoli and finally into the body tissues.
Thus, the answer is nasal cavity, pharynx, larynx, trachea and bronchi.

What molecule is essential to regenerate at the end of the Krebs cycle to start the process again
Answer:
Oxaloacetate
Explanation:
Throughout the citric acid cycle, in the matrix of the mitochondria, the 4 carbon molecule is transformed (through the addition and removal of carbon atoms) and ultimately regenerated before the beginning of another cycle. During this transformation of oxaloacetate, some intermediate products are of a lower energy level than their predecessors hence making the process energetically favorable. The energy difference is capture is energy molecules such as NADH. FADH₂, and ATP.
which of the following can be considered an ecosystem?
the community of organisms within a desert
an entire desert including abiotic factors
a population of fish in a small lake
the wood of a rotting log
Answer:
an entire desert including abiotic factors
Explanation:
An ecosystem includes all living (biotic) and nonliving (abiotic) factors in an area that interact, therefore an entire desert including abiotic factors can be considered an ecosystem. The living community within a desert, the population of fish in a small lake, and a rotting log are all examples of an ecosystem due to their combined biotic and abiotic components.
Given the options presented in the question, an entire desert including abiotic factors can be considered an ecosystem. This is because the term ecosystem applies to a natural unit consisting of all the living organisms in an area functioning together with the nonliving physical factors of the environment. A community of organisms within a desert or a population of fish in a small lake both represent biotic communities, while the wood of a rotting log can also be classified as an ecosystem due to the interacting species and abiotic factors present.
