Answer:
Some individuals are predisposed to medical conditions such as that were
inherited from their parents due to "genetic predisposition"
Explanation:
A genetic predisposition (occasionally also named genomic vulnerability) is an improved probability of emerging a specific illness created on a being's inherent makeup. A genetic predisposition consequence from precise inherent disparities that are often congenital from a parent. These inherent variations subsidize to the growth of a illness but do not straight cause it. About people with a predisposing inherent disparity will not ever get the sickness though others will, even inside the similar family.

Explanation:
Took it
The image portrays Charles Darwin's theory of Natural Selection, specifically the principle of competition within a population due to a limit in resources. Characteristics that provide an advantage in this competition are more likely to be passed on to the next generation. The oryx's might be competing for resources like food, water, or mates, leading to an evolution of the population over time through survival of the fittest.
Explanation:The image of the two male oryx's in your question seems to depict one of Charles Darwin's main points, this being natural selection, which is a key mechanism of evolution. The principle of competition within a population is central to Darwin's theory of natural selection. According to this theory, more offspring are produced than can survive due to limited resources, leading to intra-species competition. Characteristics that provide an advantage in this competition are more likely to be passed on to the next generation. Thus, those who inherit the favorable traits have a higher chance of survival and reproduction.
From the example of the two oryx's, we may guess that they might be competing for resources such as food, water, territory, or mates. This competition could lead to survival of the fittest where the oryx with the best suited traits for survival in its specific environment would have more offspring that will share those traits, leading to an evolution in the population over generations.

What does the Earth look like after its collision with Theia (the collisio
that formed the Moon)?
Answer:
The Earth looks like an oblong non-uniform object after its collision with Theia (the collision that formed the Moon)
Explanation:
Though the size of Earth was very small compared to Theia, the Earth survived in the sideway collision and the moon was gradually formed. Theia is believed to be of the size of Mars and its diameter was approximately 3,800 miles. Many wonder how Earth survived the collision with Theia and stay intact in its orbit.Following the collision with Theia, Earth was left in a molten state, with debris from the impact forming the Moon. Earth's surface has been reshaped by plate tectonics and erosion, hiding evidence of such ancient impacts.
Explanation:Aftermath of Earth's Collision with TheiaThe Earth after its collision with Theia, a Mars-sized body, was a dramatically altered planet. The Giant Impact Hypothesis suggests that this collision occurred around 4.5 billion years ago and was powerful enough to send debris into orbit around Earth, which eventually coalesced to form the Moon. The impact would have left Earth extremely hot, with a surface covered by a magma ocean. Craters like those on the Moon are less visible on Earth due to processes like plate tectonics and erosion, which have continually reshaped Earth's surface, erasing such ancient impact scars.

Show me a ribosome location in a cell structure
Answer:
Ribosomes are found moving freely in the "cytoplasm and sometimes can be seen attached to the Endoplasmic Reticulam"
Explanation:
In the cytoplasm the RIbosomes are found moving freely, but sometimes it has been observed that ribosomes are attached with the Endoplasmic Reticulam and forming the rough Endoplasmic Reticulam. When the ribosomes are bound to the particular mRNA strand, the structure formed is known as polysomes. The existence of the ribosomes are not permanent as well. Basically the ribosomes are made up of the nucleolus. Ribosomes helps in the making of the protein.
7. What role do plants play in the water cycle?
Answer:
absorb ground water.
Explanation:
Role of Plants in Water Cycle
They absorb groundwater, that is, water collected below ground level due to percolation of rain water, through their root system. ... Vegetation plays an important role in the water cycle by preventing soil erosion and increasing groundwater levels.
Plants play a crucial role in the water transport from the ground to the atmosphere - a process known as transpiration. This not only helps in the redistribution of water but also in temperature regulation. During periods of drought, plants can conserve water by closing their stomata.
Explanation:Plants play an integral part in the water, or hydrologic, cycle. They absorb water from the soil through their roots due to the properties of water molecules. This process is known as transpiration. The water is then transported from the roots, up through the stem, and to the leaves. Once in the leaves, the water evaporates into the atmosphere, contributing to the formation of clouds and precipitation.
The process by which plants pull water from the ground and release it as water vapor is crucial to the environment. Not only does it help in the redistribution of water, but it also aids in temperature regulation, as the evaporation process has a cooling effect.
However, plants also have an important role in the conservation of water, especially during periods of drought. Certain mechanisms within the plant can cause the stomata to close, reducing water loss and helping the plant conserve water.

Snake's and worms have no legs and share a similar tube-like body structure.
Describe how you could determine how closely related these two types of organisms are.
Can someone please help me out.
I will mark you brainlylist
Answer:
Snake and worm are not closely related. Snakes are vertebrates (with a backbone) while worms are invertebrates (with no backbone). So, snake and worms have different anatomy. But the apperance of both organisms have similar features: worms has long, thin, and shiny body which looks like a snake but both have no legs. Movement patterns for both are also similar. Similarly, both organisms show a similar type of skin, habitat, and sensory organs.
Final answer:
To determine how closely related snakes and worms are, comparative anatomy, molecular biology, and evolutionary biology techniques are employed to examine the structural, genetic, and evolutionary differences between these organisms.
Explanation:
To determine how closely related snakes and worms are, one approach is to use comparative anatomy, which involves examining the structural similarities and differences between organisms. Despite their similar shape, snakes are vertebrates as they have an internal skeleton, whereas worms encompass various invertebrate groups such as flatworms, roundworms, and segmented worms, each with different anatomical features. For example, roundworms are pseudocoelomates with a complete digestive system, while flatworms lack a respiratory or circulatory system. Snakes, on the other hand, have evolved from a tetrapod ancestor and possess complex organ systems, such as a three-chambered heart and a very flexible jaw.
Molecular biology is another method used to assess relationships, through examining DNA and protein sequences to quantify genetic similarities and differences. Lastly, the field of evolutionary biology which includes phylogenetic analysis helps in constructing evolutionary trees that depict relationship histories based on shared characteristics and genetic data.

Look at the diagram of the cell membrane. Would a cell membrane be able to function in the same
way if it was composed of saturated fatty acids? Explain. (4 points)
Explanation:
The membrane would be too rigid. The unsaturated fatty acids allow the membrane components to maintain their fluid mosaic structure-the components slip past each other freely and adjust to changes in osmotic pressure within the cell.
Further Explanation:
Lipids consist of fatty acids forming the hydrophobic tail and glycerol forming the hydrophilic head; glycerol is a 3-carbon alcohol that is water-soluble, while the fatty acid tail is a long chain hydrocarbon (carbon-backed hydrogen) of up to 36 carbohydrates.
Their polarity or arrangement can confer hydrophilic and hydrophobic properties on these non-polar macromolecules. Small water molecules can pass through the phospholipid bilayer through diffusion into the extracellular fluid or cytoplasm as a semi-permeable membrane, both of which are hydrophilic and contain large concentrations of polar water molecules or other water soluble compounds. The heads of the bilayer are hydrophilic the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Other components include:
Cholesterol: The comparatively rigid cholesterol anchors other molecules attached to the membrane, maintains membrane stability or structural integrity, and helps to separate some lipids, helping with membrane fluidity at low ambient temperatures. Transmembrane proteins are embedded from the extracellular fluid into the cytoplasm within the membrane, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) that function as cell surface marker.Learn more about membrane components at https://brainly.com/question/1971706

D: When a high- and a low-pressure air mass are far apart, air moves slowly from high to low pressure.
E: The greater the difference in pressure, the faster the winds.
Answer: is Option E and Option D.
D: When a high and a low pressure air mass are far apart, air moves slowly from high to low pressure.
E: The greater the difference in pressure, the faster the winds.
The rules in the movement of the air masses is quite easy and simple. The air masses with high pressure always move towards the air masses with lower pressure. The wind speed is lower when the difference in the air pressure is very small. Similarly the wind is speed is faster when the difference in the air pressure is larger.
When air pressures are far apart with different pressures (low and high), there will be no movement of air, or a gradual slow movement occur resulting in slower wind speed.

The correct answer is : They lack DNA/RNA so they must use the DNA of the host cell.
Explanation:
In general, Viruses are composed of two major parts, a genetic material - DNA or RNA (depending upon the type of virus) and a capsid protein coat that encloses and protects the genetic material.Without a genetic material no matter can be considered as living as there will be no multiplication and replication possible.Viruses need the host for its metabolism, replication and multiplication process.After infection, they hijack the cells protein-synthesising machinery, the ribosomes, and utilise the host cell's energy (ATP) for synthesising their own proteins encoded in their genetic material.They utilise the basic components of the host cell like amino acids, nucleotides and lipids for synthesising their own proteins, replicating and producing multiple copies of their genetic material and also producing their coat proteins and lipids.This way the infection-causing virus produces multiple virion particles that exit the infected host in search for new host and repeating this life-cycle.if the gametes are produced by a female what are they called

Answer:
mass and distance
The factors determine strength of gravitational force between two objects is mass and distance. Thus, option A is correct.
What is law of conservation of mass?The declaration that best represents the law of conservation of mass is as follows:
Mass of Reactants = Mass of Products.
The law of conservation of mass states that the overall mass of substances that remarkably take part in a chemical reaction is conserved during the reaction. It is neither created nor destroyed in a chemical reaction.
As a result of this, the mass of substances during a chemical reaction remains the same. This implies that the mass of reactant molecules is definitely equal to that of the mass of the product molecules. The mass of reactants equal to the mass of products is the statement that best represents the law of conservation of mass.

Which of the following observations is true concerning the effect of body mass on demographics?
a. The higher the body mass, the higher the population density
b. The lower the body mass, the higher the population density
c. The higher the body mass, the higher the population size
d. The lower the body mass, the higher the population size
Answer: D
Explanation: If the body mass is low that means there will be higher the population size. It's the law of nature the species which have lower body mass are more in number and vice-versa. So the answer is the Delta option.
Final answer:
The correct answer is b. The lower the body mass, the higher the population density, due to smaller organisms' lower per-individual resource needs and ability to live closer together.
Explanation:
The question concerns the relationship between body mass and population demographics, specifically population density. Based on the information provided, which repeatedly indicates that population density typically decreases with increasing body mass, the correct answer is b. The lower the body mass, the higher the population density. This phenomenon occurs because smaller organisms often require fewer resources per individual and can live in closer proximity to one another than larger organisms. Thus, areas can support a higher number of smaller individuals than larger ones, leading to a higher population density among species with smaller body mass. Examples include how insects can have very high population densities in a given area compared to larger mammals.

How do glycoproteins help the mucus to trap substances
Answer:
The sugar in glycoprotein mix with water in order to form a "smooth mucus." This mucus is responsible for trapping the substances in order to protect the body.
Explanation:
"Glycoprotein" was named according to its composition because it is a simple protein consisting of simple sugar. It can be found in cell's membrane, thus it is directly related to the organs in the body.
Glycoproteins mainly function in the body's "immunology" and "protection." When it comes to immunology, glycoproteins assist the body in blood clot formation. When it comes to protection, they provide a "smooth mucus" that protects the cell linings from agents (e.g. bacteria or harsh acids) such as those in the lungs, stomach and small intestines.
