When oxygen becomes depleted in the mitochondria, the following options apply:

a. The anaerobic system takes over and lactic acid builds up.

b. NAD builds up.

c. The electron transport chain "backs up" and electrons no longer are passed (all complexes are reduced).

a. The anaerobic system takes over and lactic acid builds up:

When oxygen becomes depleted in the mitochondria, the cell switches to anaerobic respiration to produce energy.

During anaerobic respiration, glucose is converted into lactic acid, resulting in the buildup of lactic acid. This process is known as lactic acid fermentation.

b. NAD builds up:

NAD (nicotinamide adenine dinucleotide) is an important coenzyme involved in cellular respiration. In the absence of oxygen, NADH (the reduced form of NAD) cannot be effectively converted back to NAD+. As a result, NAD accumulates in its reduced form (NADH).

c. The electron transport chain "backs up" and electrons no longer are passed (all complexes are reduced):

The electron transport chain (ETC) is a series of protein complexes located in the inner mitochondrial membrane.

Its primary function is to transfer electrons from NADH and FADH2 (produced during earlier stages of cellular respiration) to oxygen, creating a proton gradient that drives ATP synthesis.

When oxygen becomes depleted, the final electron acceptor in the ETC is no longer available.

As a result, the ETC becomes "backed up," and electrons can no longer be passed through the chain. This causes a buildup of reduced forms of electron carriers (such as NADH) and reduces the efficiency of ATP production.

d. Electrons are not passed faster through the ETC to compensate for the lack of oxygen:

The electron transport rate is not increased in response to oxygen depletion. The ETC operates based on the availability of oxygen as the final electron acceptor. Without oxygen, the ETC cannot function properly, and speeding up the electron transfer does not compensate for the lack of oxygen.

Thus, the Option d is not correct: Electrons are not passed faster through the electron transport chain (ETC) to compensate for the lack of oxygen.

Transcription involves the transfer the information from DNA to RNA.

Transcription is the synthesis of RNA from DNA. Genetic information flows from DNA into protein, and the substance that gives an organism its form. This flow of information will occurs through the sequential processes of the transcription (DNA to RNA) and translation (RNA to protein). Transcription will occurs when there is a need for a particular gene product at a specific time or in a specific tissue.

During the transcription, only one strand of DNA is usually copied. This is called as the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or the sense strand.

The term used to describe the influences of multiple genes on behavior is called "polygenic inheritance."It refers to the transmission of characteristics from one generation to the next in which several genes determine the phenotype of an organism.

When traits or characteristics are determined by more than one gene, they are said to be polygenic. Examples of polygenic inheritance include height, weight, skin color, and eye color. A polygenic inheritance occurs when several genes contribute to a particular trait or characteristic in an organism.

Since most traits are influenced by multiple genes, polygenic inheritance is common in many organisms, including humans. Complex behaviors like language, intelligence, and personality are also believed to have a polygenic basis.

The study of polygenic inheritance is essential for the understanding of complex traits. In most cases, it involves identifying the genes involved in the inheritance of a particular trait, analyzing the interactions between them, and determining how they contribute to the trait's expression.

Polygenic traits tend to exhibit a continuous range of variation rather than discrete categories. That is, the trait is not an either/or situation. Instead, it is a continuum, where individuals fall somewhere along a spectrum.

For example, height in humans is a polygenic trait that shows a continuous distribution of values from short to tall. This continuous distribution results from the combined effects of several genes, each of which contributes a small amount to the overall height of an individual.

Answer:

they are called monomers

Explanation:

Yes, we are running out of resources. Some of the resources that are rapidly depleting are oil, coal, natural gas, and metals. The common characteristics that these resources share are that they are finite and non-renewable, which means that they can't be replenished at the same rate as they are being consumed.

Oil is one of the most important resources that we use, as it is used to produce gasoline and other fuels that power vehicles and machinery. It is also used in the production of plastics, fertilizers, and pharmaceuticals. However, oil is a finite resource and there is a limited supply of it. According to the International Energy Agency, global oil demand is expected to rise to around 105 million barrels per day by 2025, which is an increase of around 6 million barrels per day from current levels. As a result, there is concern that we may soon reach "peak oil", which is the point at which global oil production reaches its maximum and starts to decline.

Coal is another non-renewable resource that is rapidly depleting. It is used to produce electricity, as well as steel and cement. However, coal is also a major contributor to greenhouse gas emissions and air pollution, which has led to calls for a transition to cleaner forms of energy.

Natural gas is a cleaner alternative to coal and oil, but it is also a finite resource that is rapidly depleting. It is used to produce electricity, heat buildings, and power vehicles. However, like oil and coal, natural gas is a non-renewable resource that takes millions of years to form and is extracted from the earth's crust.

Metals such as copper, gold, and silver are also non-renewable resources that are rapidly depleting. They are used in a wide range of industries, including construction, electronics, and transportation. However, the extraction and processing of metals can have negative environmental impacts, such as deforestation, habitat destruction, and water pollution.

In conclusion, we are running out of resources such as oil, coal, natural gas, and metals. The common characteristics that these resources share are that they are finite and non-renewable, and take millions of years to form. This means that we need to find new, sustainable ways of producing energy and materials to meet our needs without depleting the earth's resources.

THE ANSWER IS PLASTIC

Vibrio cholerae, the bacterium responsible for cholera, has a specific sensor that can detect changes in pH. The ability of Vibrio cholerae to sense pH is related to its ability to cause an intestinal infection.

Vibrio cholerae has the ability to survive the acidity of the stomach and colonize the small intestine. The pH of the small intestine is mildly acidic. Vibrio cholerae senses the change in pH of the small intestine and produces two proteins: ToxT and TcpP/TcpH. These proteins, in turn, activate the expression of virulence genes.

Vibrio cholerae has evolved a two-component regulatory system called ToxR/ToxS. The ToxR/ToxS system works by sensing the changes in pH between the stomach and the small intestine. When Vibrio cholera enters the small intestine, ToxR/ToxS is activated, leading to the activation of a set of genes that encode factors responsible for causing an intestinal infection.A part of the ToxR/ToxS regulatory system of Vibrio cholerae involves two other proteins, TcpP and TcpH.

These proteins help in the transmission of signals between the cell surface and the cytoplasm, allowing the bacterium to respond to the changing environment and express virulence genes.TcpP/TcpH and ToxT are transcriptional regulators that activate the virulence genes that encode the cholera toxin. The cholera toxin is responsible for the hallmark symptoms of cholera, such as severe diarrhea and vomiting.

In conclusion, Vibrio cholerae senses pH changes in the small intestine using its ToxR/ToxS two-component regulatory system, which activates the expression of virulence genes. TcpP/TcpH and ToxT proteins are transcriptional regulators that activate the expression of virulence genes encoding the cholera toxin.
