The number of possible genetically different gametes of an organism depends on the genotype of the organism.
What are gametes?Gametes are generated when sex cells divide meiotically in sexually reproducing living organisms.
The different gametes that can be produced as far as genotype is concerned depend largely on the genotype of the parent.
Parents that are homzygous for a particular trait will produce gametes that are genetically the same for that trait.
Whereas, parents that are heterozygous for a trait will produce gametes that are genetically different for the trait. Some gametes will have dominant alleles while others will have recessive alleles.

Underdominance tends to _____________ the number of heterozygotes over many generations
Underdominance tends to lower the number of heterozygotes over many generations.
Heterozygous having a disadvantage in reproductive success is called underdominance. This condition is also called negative overdominance.
Underdominance cannot preserve genetic variation, and one of the alleles will either be lost or spread to fixation depending on its initial frequency.
In evolution, the selection favoring heterozygotes is called overdominance while the selection favoring homozygotes is called underdominance.
An example of underdominance can be seen in an African butterfly species (Pseudacraea eurytus) which utilizes batesian mimicry to escape predation. They have two alleles to confer the appearance of local butterflies that are toxic to predators.
The butterfly with heterozygous allele shows an intermediate appearance and thus experiences increased predation than the butterfly with homozygous alleles.

Drag each tile to the correct location. classify the events according to the gas they primarily contribute to the atmosphere. cattle digest food. animals perform respiration. forest fires burn. plants perform photosynthesis.
Cattle digest food - methane and carbon dioxide
Animals perform respiration - carbon dioxide
Forest fires burn - carbon dioxide, carbon monoxide, and methane
Plants perform photosynthesis = oxygen
Events and the gas they contributeCattles are able to digest cellulose, fibers, and their likes through the activities of certain bacteria. The process happens through the enteric fermentation of these materials. Thus, carbon dioxide is produced as well as methane.
During respiration, carbohydrates in the form of glucose are broken down to extract the lock-up energy for biological processes. In addition to water, carbon dioxide is also produced as a by-product.
Burning forests leads to the emission of gases like methane, carbon dioxide, and carbon monoxide.
During photosynthesis, inorganic materials are used to synthesize carbohydrates with the by-product being oxygen gas.

How would you describe the environment a pathogen would encounter in the small intestine?
The environment that a pathogen would encounter in the small intestine would be harsh and unfavorable for its existence.
The small intestine has a harsh environment for microbial life on account of short transit time, the influx of digestive enzymes as well as bile and intermittent food substrate delivery.
The intestinal microbiota is the collective term used to describe the large and diverse microbial community that inhabits the intestine.
An important benefit provided by the intestinal microbiota to the host intestine is the protection from colonization by exogenous pathogens (a phenomenon nowadays termed as colonization resistance) and from overgrowth of indigenous pathobionts i.e. potential pathogenic symbionts of the microbiota.

Which relatively rare type of neuron has two processes extending from opposite sides of the cell body?
Bipolar neuron has two processes extending from opposite sides of the cell body.
Typically, neurons consist of a cell body and one or more extensions. Dendrites (short extensions with ramifications) and axons are the two forms of extension (just one extension of varying length depending on the cells).
Two processes, oppositely extending from the cell body's ends, are present in bipolar cells. One is the dendrite, the other the axon. Bipolar neurons are not common. They are sensory neurons that can be found in the vestibulocochlear nerve's ganglia, olfactory epithelium, and retina.
Therefore, Bipolar neuron has two processes extending from opposite sides of the cell body.

What hormone helps to maintain extracellular fluid (ecf) osmolality when concentrations become too high?
Vasopressin, also known as Antidiuretic hormone (ADH) helps to maintain extracellular fluid (ECF) osmolality when concentrations become too high.
When osmolality increases, it stimulates the body to produce Antidiuretic hormone (ADH). This hormone instructs the kidneys to retain more water inside the blood vessels as a result, the urine becomes more concentrated.
Osmolality refers to the concentration of dissolved particles of chemicals and minerals like sodium and other electrolytes in the serum. Osmolality increases when the body is dehydrated whereas, it decreases when too much fluid in present in the blood.
Antidiuretic hormone (ADH) or Vasopressin checks the amount of water reabsorbed from the nephrons. This regulates the water content of the blood which is termed as osmoregulation.

The process whereby heat flows by means of molecular collisions is referred to as:________
The process whereby heat flows by means of molecular collisions is referred to as conduction.
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.
Because in conduction molecules are closely packed. When one molecule is heated, it vibrates higher than lower energized molecules or the lower temperature molecules and collide with and finally transfer some energy to them.
The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.

What are the 4 ways or mechanisms by which a planet or moon can gain an atmosphere?
Four processes—outgassing, evaporation, sublimation, and surface ejection—can help a planet or moon to gain an atmosphere.
1) Outgassing: The release of a gas that has been dissolved, trapped, frozen, or absorbed in a substance is known as outgassing.
The outgassing that took place as the smaller, inner planets cooled down is likely how they acquired their atmospheres (volcanoes).
2) Evaporation : The process of converting anything from a liquid or solid state to vapors is called evaporation (like fog, mist, or steam).
So upon evaporation, water converts into gas and that's how moon gain an atmosphere by evaporation.
3) Sublimation : Converting a solid directly into a gas without first going through a liquid phase.
4)Surface ejection: A surface ejection is a massive discharge of plasma and magnetic field into the heliosphere from the Sun's corona.

A. Leguminism

D. Mutualism
Answer:
Mutualism
Explanation:
Mutualism is when two species work together to benefit each other. Like there are certain species of bird that sit on rhinos and eat pests/bugs on them, this benefits the bird cuz it gets food and it benefits rhino cuz it does not get bugged (pun intended)
Cattle egret follow herds of cattle and feed on both the insects stirred by the movement of the cattle and the biting insects that irritate the cattle. this is an example of:______.
Commensalism relationship is shown between cattle egret and cattle.
Usually cattle egrets follow herds of large hoofed mammals such as cattle, buffalo. They eat the insects that have been stirred up by the buffalo as they move. This relationship is commensalism, because the birds benefit but the ungulate is neither harmed nor helped.
The cattle egret and grazing cattle in a close association is a classic example of commensalism. It is a common sight in rural areas where one can see ticks hovering over the cattle. They feed on cattle's blood and hence are harmful to them as they can transmit several diseases. The cattle egret and grazing cattle in a close association is a classic example of commensalism.

The most significant factor contributing to widespread edema brought on by decreased plasma protein production in chronic liver disease is hypoalbuminemia, which manifests in end-stage liver disease. It leads to the increase on capillary filtration/absorption .
The osmotic pressure in blood arteries is maintained in large part by plasma proteins, which are also crucial carriers of several chemicals, including hormones. Blood pressure is the main factor influencing Glomerular filtration rate (GFR), which is countered by Bowman's capsule fluid pressure and colloid osmotic pressure brought on by plasma proteins.
