The factors like genetic mutations, random mating, gene flow and genetic drift can increase genetic variance.
Genetic variations are the changes which occur in the genetic sequence of the DNA. These genetic variations are necessary as they allow the living beings to evolve and eventually survive. There are some factors which cause an increase in the genetic variation and they are genetic mutations, random mating, gene flow and genetic drift.
A genetic mutation is an alteration in the DNA sequence of a particular gene which causes a different product to form. This helps increase the genetic variance in organisms. Gene flow is defined as the movement of genes in and out of a particular population. In-flow of genes can help increase the genetic variation of individuals in that population. Genetic drift is the change in allelic frequency in a population by chance. Random mating is the mating of individuals that is not especially dictated by any social or genetic preference and leads to an increase in variation.

Darron lost his sense of taste because a tumor caused damage to a structure located on top of his brainstem. This structure is known as the
The structure located on top of Darron's brainstem that caused him to lose his sense of taste is called the nucleus of the solitary tract (NTS).
The NTS is part of the autonomic nervous system and is responsible for relaying taste information from the tongue to the brain. The NTS is also involved in the control of breathing, blood pressure, and other bodily functions. In Darron’s case, a tumor in the vicinity of the NTS caused damage to the nerve cells in the area, resulting in a disruption of the signals that travel from the tongue to the brain. This has led to a complete loss of his sense of taste.
Although the tumor is the cause of Darron’s loss of taste, it is the damage to the NTS that is responsible for the symptom. The NTS is located in the medulla oblongata, which is a major part of the brainstem and is responsible for controlling many of the body’s involuntary functions.
The NTS is a cluster of neurons that receive taste information from the tongue, and then relay it to the brain. When the cells of the NTS are damaged, the signals that travel from the tongue to the brain are disrupted, resulting in a complete loss of taste.

Cellular Communication and the Cell Cycle FRQ:
a) Low extracellular pH activates TRPV1 through the binding of H + ions to TRPV1. Describe the properties, including the location, of the site of TRPV1 that allow H+ ions to bind. Describe the specific location in the cell where ATF3 protein is produced.
b) The pGoG protein is known to block the G1 to S transition in the cell cycle. Explain why this prevents mitosis from happening in the cell
Specifically, in sensory neurons, the plasma membrane of cells contains the cation channel protein TRPV1. Heat and low extracellular pH are only two of the many triggers that might cause it to become active.
The protein TRPV1 undergoes a conformational shift in response to the adsorption of H+ ions, opening the ion channel and allowing calcium ions to enter the cell. The subsequent signaling pathways that result in the perception of pain are activated by this calcium ion inflow.
ATF3 protein is exclusively synthesized in the cytoplasm of the cell, more particularly in the nucleus, where it is transcribed from the ATF3 gene.
The pGoG protein is known to block the G1 to S transition in the cell cycle by inhibiting the activity of the cyclin-dependent kinase (CDK) that is responsible for initiating DNA replication. This prevents mitosis from happening in the cell because, without DNA replication, the cell cannot divide.
Additionally, the pGoG protein also promotes the activity of the tumor protein p53 which is also known as the "guardian of the genome" and helps to prevent DNA damage and cell mutations, when it is activated it can stop the cell cycle and prevent mitosis from happening.

Mucous secretions in the respiratory tract inhibit microbial infections. These secretions are produced by which of the following tissue types found in the lungs ?
A. Epithelial
B. Glomerulus
Option A: Epithelial tissue types found in the lungs are responsible for mucous secretion in the lungs.
About 30% of the respiratory epithelium's total cell population are goblet cells. They create mucinogen, which when released into an aqueous environment becomes hydrated and is known as mucin. As soon as the mucin is combined with additional components in the wet environment, it is referred to as mucus. Thus, option A is the appropriate choice.
The first line of defense against the onslaught of irritants that 500 L of air an hour of air inhalation puts into the lungs is mucus secretion.

The producers in the ecosystem produce 25,000,000 kilocalories per year. How much energy is most likely available to the organisms in Level 3 of the pyramid
The energy available to the organisms in Level 3 will be much less than the 25,000,000 kilocalories that are produced in the ecosystem each year.
This is because energy is lost due to metabolic processes, respiration, and other losses as the energy moves from one trophic level to the next.
For example, in a typical food chain, producers are at the bottom and represent about 10% of the total energy available. This means that of the 25,000,000 kilocalories produced each year, only 2,500,000 kilocalories are available for the primary consumers in Level 2. As the energy moves up the pyramid, the amount of energy available to each level decreases. By the time it reaches Level 3, only a fraction of the original energy remains.
In addition to energy losses as the energy moves up the pyramid, organisms in Level 3 may also compete with each other for the available energy. This competition will further reduce the amount of energy available to them.

Why do phospholipids tend to spontaneously orient themselves into something resembling a membrane?
Phospholipids tend to spontaneously orient themselves into something resembling a membrane because of their unique chemical structure. Phospholipids are composed of a polar, hydrophilic (water-loving) head and a nonpolar, hydrophobic (water-fearing) tail.
When phospholipids are in an aqueous environment, such as in water or in the cell, the polar heads of the phospholipids interact with the water molecules, while the nonpolar tails are repelled by the water molecules and tend to aggregate together. This creates a barrier that separates the polar heads from the nonpolar tails, which is known as a lipid bilayer.
The hydrophobic effect is the main driving force for the self-assembly of phospholipids into bilayers. The hydrophobic effect is the tendency of nonpolar molecules to aggregate together in order to minimize the number of polar interactions with the surrounding water molecules. This effect drives the phospholipids to align their hydrophobic tails together, creating a barrier that separates the hydrophilic heads from the hydrophobic tails.
