It produces male and female sex cells.

The statement is false because both temperature and pressure play crucial roles in determining the state of matter, alongside intermolecular forces and energy changes.

While temperature is a critical factor in determining the state of matter (solid, liquid, and gas), it is not the only factor; pressure also plays a significant role. For example, water can exist as ice (solid), liquid water, or steam (gas) primarily dependent on temperature.

However, the application of pressure can alter the temperature at which these changes occur. Atmospheric pressure impacts the boiling point of liquids, which is why water boils at a lower temperature at higher elevations where air pressure is lower. Moreover, the ability of a substance to change states between solid, liquid, and gas involves energy changes and intermolecular forces, indicating that the state of matter is the result of a balance between kinetic energy (dependent on temperature) and intermolecular attractions (which can be influenced by pressure).

The question is:

True or False:

Solid, liquid and gas states of matter are determined only by temperature.

A. glucose

B. O2

C. Enzyme

D. CO2

Glucose + O2 → CO2 + ATP + H2O (in the presence of Enzyme)

Cellular respiration is a reverse process of photosynthesis. During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.

Answer: B

A-Glucose

B-Oxygen

C- Enzyme

D- CO2

Complete Equation

Glucose + Oxygen → ATP +  C02  + H20.

                            enzyme

Explanation:

This  represented the chemical pathway of Cellular respiration. it is the process of breaking down glucose in the cytoplasm to pyruvate in presence of enzymes(hexokinase, phosphorfructokinase) the process is called  Glycolysis,

The use of the pyruvate as acetyl Co A combined with oxaloacetate to generate ATP, and produce C02 and H20 vapour as by-products in a pathway called Kreb-Cycle. H+ are removed by Coenzymes NADH+ and FADH+

The NADH+ and FADH+  are transferred  to the mitochondria matrix , where Hydrogen  is split to H+ and e-for ECT,  The e- forms the electron transport chain, and while the H+ is pumped by PMF across the mitochondria intramembrane to generate energy  from electrochemical gradients which is needed  for ATPs synthesis, by ATPase synthase. Oxygen is the final oxygen acceptor.    

Thus option B is the answer.

Answer:

Point source pollution:

Non-point source pollution:

Explanation:

According to United States Environmental Protection Agency (EPA) regulations, point source pollution is a type of pollution in which contaminant is released into the environment from an easily identified source. In the examples given above, smoke from a factory, sewage, and oil effluents are coming from easily identifiable sources.

On the other hand, a non-point source of pollution is the release of contaminant in the environment through diffused or unidentifiable sources. In the examples given above, smoke from cars could be stated as non-point sources of pollution because vehicles are in a continously moving state.

Smoke from a factory and sewage are classified as point source pollution due to their identifiable origins, whereas smoke from cars represents non-point source pollution due to its diffuse sources. Oil from a garage can be classified as point source pollution when it comes from a particular location.

The classification of pollution sources into point source pollution and non-point source pollution is based on their emissions and locations. Point source pollution comes from identifiable, confined, and discrete locations, while non-point source pollution comes from widespread, diffuse sources.

Understanding these distinctions helps in the application of environmental regulations and informs the strategies for mitigating the impacts of pollution.

Answer:

So many factors influence the climate. Some of them are ocean currents, latitude, distance from the ocean, elevation, etc.

Explanation:

The distance from the ocean influences the climate of the place. If the place is located on the coast, the climate will be colder and humidity will be higher.

Thanks to ocean currents the temperature can be changed. Ocean currents can low the temperature but also make it very high.

Latitude has an influence also regarding the temperature. Elevation, as it gets higher, the air above is falling, so the pressure decreases.

Regarding all the factors above, we can say that New York has hot summers, with high humidity and very cold winters, full of snow. Close to the river, the ground is muddy and going to the mountains, the ground is getting rocky

Answer:

At each stage of the trophic levels, only 10% energy is transferred from one level to another.

Explanation:

In an ecosystem transfer of energy from one stage to another is very inefficient. From first stage to next stage only 10% energy is transferred to next trophic level. Rest 90% lost in environment.

This is known as  LINDEMAN's TEN PERCENT LAW. Given by Raymond lindeman.Only 10% energy from one trophic level to next trophic level is transferred. Rest is used in respiration, breakdown etc.

First stage of trophic level has the highest energy and the last trophic level has the lowest amount of energy.

About 90 percent of energy is lost at each trophic level, used for metabolic processes, growth, repair, and released as heat. The second law of thermodynamics explains these losses. This results in typically no more than four trophic levels in a food chain.

At each stage of the trophic levels, about 90 percent of the energy is lost. This energy is used by organisms at that level for their metabolic processes, growth, and repair. Notable is the production of heat or thermal energy, which is lost to the environment.

This loss of energy from one trophic level to the next is in accordance with the second law of thermodynamics, stating that there is a tendency toward disorder (entropy) in any system where energy is converted from one form to another.

As a result of these energy losses, there are typically fewer organisms and less biomass at higher trophic levels and rarely more than four trophic levels in a food chain or web, due to insufficient energy to support additional organisms.

Answer:

D. all of the above​

Explanation:

Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.  

For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.

Answer:

The answer is b or  The species could be human because it has gill slits, limb buds, and a tail.

Explanation:

When Humans are in the embryology stage we have tails, gill slits, and also buds of that are the beginings for limbs

They offer solid proof of natural selection. The tail and gill slits found in all early vertebrate embryos are just two examples of embryological evidence that suggests similar ancestry. Thus, option B is correct.

In fact, young human embryos do have slits in their necks that resemble gills. Instead of because we go through a “fish stage” while growing into physiologically perfect beings within our mothers' wombs.

Due to a shared ancestor and some DNA between humans and fish, this is almost certainly true. Given that it has limb buds, gill slits, and a tail, the species might be human.

In chordates, the anterior part of the digestive tract (pharynx) has pouches or slits. These are present during development in all vertebrate species and play a role in gas exchange and feeding in fish and some amphibians.

Therefore, When Humans are in the embryology stage we have tails, gill slits, and also buds of that are the beginnings for limbs.

Explanation:

Atom has three subatomic particles;

Electron : Negatively charged species found inside an atom and outside of the nucleus.

Proton: Positively charged species found inside the nucleus of an atom.

Electron : Neutral charge species found inside the nucleus of an atom

Generally an atom is an electrically neutral species with equal number of electrons and protons.

According to question,The correct labeling of the U is an electron.

The part of the atom that is shown in the diagram is the U as electron that is in option C. Electrons are negatively charged subatomic particles that are present outside of the nucleus. So option C is correct.

Protons are positively charged subatomic particles found within the nucleus of an atom. They have a relative charge of +1 and a relative mass of approximately 1 atomic mass unit (amu). The number of protons in an atom's nucleus determines its atomic number, which is a fundamental property used to identify elements. Neutrons are electrically neutral subatomic particles also located in the nucleus of an atom. They do not carry any charge, so their relative charge is 0. Neutrons have a mass similar to protons, approximately 1 amu. Electrons are negatively charged subatomic particles that orbit the nucleus in specific energy levels, or electron shells. 

Hence, electron is correct option . So, option C is correct.

Bilateral symmetry in animals facilitates directional movement and complex behaviors, differing from radial and asymmetrical forms. Cephalization and triploblastic tissue structure in bilaterally symmetrical animals imply advanced body plans connected to their active lifestyles.

Bilateral symmetry is a fundamental characteristic of many animals, where a longitudinal section divides the organism into mirror-imaged right and left sides. This form of symmetry is closely associated with the concept of cephalization, which is the development of a head with sensory organs and nervous tissue concentrations, crucial for navigating the environment. Animals such as butterflies, crabs, and humans are typical examples of organisms with bilateral symmetry. In contrast to radial symmetry, seen in stationary or sessile aquatic animals like sea anemones, bilateral symmetry facilitates directional movement and complex behavior patterns. While radial symmetry suits a sedentary lifestyle of feeding on surrounding water currents, bilateral symmetry is conducive to active hunting and escaping predators, enhancing an organism's ability to interact with its environment effectively.

For example, while the phylum Echinodermata, which includes sea stars and sea urchins, exhibits radial symmetry in adulthood, these organisms demonstrate bilateral symmetry during their larval stage. This phenomenon is called secondary radial symmetry and indicates their evolutionary path from bilaterally symmetrical ancestors. Most animals with bilateral symmetry are triploblastic, with tissue layers organized into an ectoderm, mesoderm, and endoderm, a structure that allows for more complex body cavities and organ systems compared to animals with other forms of symmetry.

Understanding symmetry in animals provides essential insights into the evolutionary branches and how specific body plans influence the behavior and interaction of organisms within their respective environments. Body cavities thus play a crucial role in distinguishing the development of bilaterally symmetrical animals, providing spaces for complex organ systems that support their active and mobile lifestyles.

ATP synthesis is done as the electrons move through the  1 2 3 and 4 and hydrogen ion is pushed to the intermembrane space. As the hydrogen ion comes back to the matrix through the ATP synthase enzyme the ATP is produced.

Option C

ATP synthesis takes place in the mitochondria. All the hydrogen carriers get saturated through the glycolisis and the Kreb's Cycle. As these carriers comes to the inner membrane of mitochondria, there are four complexes of different electron carriers. [tex]NADH_2[/tex] goes to the complex 1 and [tex]FADH_2[/tex] goes to the complex 2.

Each complex takes the hydrogen ion from the carriers and pushes them to the intra Membranous space of the mitochondria. There the hydrogen ion concentration increases to a severe extent. As this goes on, the hydrogen ions come back to the mitochondrial matrix through a pump which is called ATP synthase which produces one ATP molecule for 3 hydrogen ion transport. Thus ATP is produced.

The oxygen is taken by cytochrome [tex]a_3[/tex] of complex 4 which is then reduced by the electrons of the hydrogen carriers and reacted with the protons to convert it to water.

Answer: It's "C"

Explanation:NAD+ and FADH donate electrons which move through the cristae; H+ ions are pumped out of the matrix; ATP and water are produced, and oxygen is consumed.

A chicken provides protein and therefore the chicken will have the molecules present in a protein

Chicken contains essential organic molecules such as carbohydrates, proteins, lipids, and nucleic acids. Proteins in chicken are particularly valuable for their amino acids, while the nutritional quality can vary based on farming practices.

The organic molecules found in chicken include a variety of important classes necessary for the body's nutrition and biological functions. These molecules are carbohydrates, proteins, lipids (fats), and nucleic acids. Chicken provides proteins that are broken down during digestion to amino acids, which are then used by the body as building blocks for new proteins and as precursors for nucleic acids. The body also converts excess carbohydrates into glucose, which is used as energy, and stores any surplus in the form of glycogen. While the body can synthesize many molecules, essential nutrients like certain fatty acids and vitamins must come from our diet.

One of the key nutritional aspects of chicken is that it is a rich source of protein, essential for building and repairing tissues. However, it's important to note that the nutritional quality of chicken can be affected by farming practices. For instance, chicken from concentrated animal-feeding operations may have higher levels of saturated fat and lower quantities of beneficial compounds like omega-3 fatty acids compared to those from other sources.

These structures are similar because perform same job, not as a result of sharing common ancestry.

Vegitive structures that have no feasible function and seems to be residual parts from thier past ancestor. They include: the pelvic bone of a snake, and the wings of flightless birds.

Answer:

Gene regulation in eucaryotic cells represents mechanisms that influence gene expression.

Explanation:

This gene expression is regulated via repressors or activators of transcription.

Gene expression is a process that contains information from a transcript gene and translates it into a functional gene product. End products of gene expression are proteins.

Gene regulation is a process that cells and viruses are using to regulate the transformation of gene information into gene products.

Transcription factors are those proteins that regulate gene transcription. Those factors help the real genes to enter the right cells in the body.

The expression of eukaryotic genes is controlled by transcription. This transcription is controlled by proteins that are connecting to regulatory sequences and change the RNA activity. Gene regulation process is developed by combining different proteins of regulation.

Answer:

If a plant's leaves only contained the vascular tissue xylem, then it will not be possible for the plant to absorb carbon dioxide. As carbon dioxide is required for photosynthesis to occur, this means that the process of photosynthesis will not take place. As a result, the plant will not be able to produce food as photosynthesis is the process by which plants make food. This will result in the plant to die eventually in the end due to lack of food.

Answer:

- The carbon dioxide required for photosynthesis would not be absorbed and transported to the leaf cells, and photosynthesis would stop.

Final answer:

The three spheres that interact in the process of climate change due to the melting of polar ice are the atmosphere, cryosphere, and hydrosphere.

Explanation:

The increase of greenhouse gases, due to human activity, is melting sea ice at the poles and causing changes in climate. In this process, three spheres that interact are the atmosphere (where greenhouse gases such as carbon dioxide trap heat), the cryosphere (which includes all of the Earth's frozen water, particularly the polar ice that is melting), and the hydrosphere (since melting sea ice directly affects the oceans). These spheres all contribute to the Earth's climate system and are impacted by human-induced climate change.
