A coenzyme is a chemical that works in conjunction with an enzyme to activate it and aid in its function. An organic molecule that binds to the active sites of specific enzymes is known as a coenzyme and helps catalyse reactions.

To be more precise, coenzymes can serve as functional groups that are exchanged between enzymes or act as intermediate carriers of electrons during these reactions.Coenzymes, which are organic compounds, are necessary for the catalytic activity of many enzymes. They typically have vitamins or vitamin-like substances in them.

They can occasionally serve as catalysts in the absence of enzymes, however not as efficiently as when an enzyme is present.Coenzymes are mostly made from vitamins and other minor amounts of other organic vital elements. (While both types of inorganic compounds are mentioned here, some scientists restrict the word "cofactor" to them.)

The human nervous system includes billions of individual neurons that assist with internal communication.

The human nervous system consists of two main parts:

Neurons are the electrically excitable cells that make up the nerve tissues of the components of the central nervous system.

Neurons are made up of three regions;

Neurons are essential for internal communication by relaying chemical and electrical signals that help components of the nervous system communicate with effector organs. The complexity of neurons is reflected in different clades of the organism. Therefore, in addition to the structure of neurons, the number of neurons also varies from organism to organism. In humans, about 86 billion neurons contribute to the formation of nervous tissue in the brain. The number of neurons in the brain depends on multiple factors such as brain growth, history or current condition with neurodegenerative disorders, and the age of the individual.

Cellular respiration is a way where O2 is combined with foodstuff molecules. The chemical energy is thereby changed to activities that are sustainable and ignoring waste products. The key metabolic stages in cellular respiration includes glycolysis, Krebs cycle, and electron transport chain.

Glycolysis is a way to break down glucose in order to produce energy. Krebs cycle is also referred to as citric acid cycle or tricarboxylic acid cycle (TCA). It is where the cells gets it energy. The electron transport chain is responsible for the transfer of electrons to the acceptors coming from the donor.

Passive transport is not a metabolic stage in cellular respiration. It is the movement of a solute from a high electrochemical potential to a lower electrochemical potential region of the cell.

Archosaurs are a group of organisms that belong to the same clade that is Dinosauria.

There is abundant evidence that birds developed within the clade Dinosauria, which is broken down into two groups, dinosaur hips (Saurischia) and bird hips (Ornithischia). Despite the names, it wasn’t bird-hipping dinosaurs that created modern birds. Instead, Saurischia split into two groups: one that included long-necked, herbivorous dinosaurs like Apatosaurus, and the second group that gave rise to birds as bipedal predators known as theropods.

There are many similarities between late (maniraptoran) dinosaur fossils and birds, particularly in the structure of hip and wrist bones and the presence of a wishbone formed by the fusion of clavicles.

Psychology seeks to explain the mental processes and behavior of individuals by studying the interaction between mental processes and behavior on a systemic level. Therefore, the field of psychology is tightly intertwined with the study of the brain.

Explanation:

Electrophoresis is a technique commonly used in the lab to separate charged molecules, like DNA, according to size.

Gel electrophoresis is a technique commonly used in laboratories to separate charged molecules like DNA?, RNA? and proteins? according to their size.

Charged molecules move through a gel when an electric current is passed across it.

An electric current is applied across the gel so that one end of the gel has a positive charge and the other end has a negative charge.

The movement of charged molecules is called migration. Molecules migrate towards the opposite charge. A molecule with a negative charge will therefore be pulled towards the positive end (opposites attract!).

The gel consists of a permeable matrix, a bit like a sieve, through which molecules can travel when an electric current is passed across it.

Smaller molecules migrate through the gel more quickly and therefore travel further than larger fragments that migrate more slowly and therefore will travel a shorter distance. As a result the molecules are separated by size.

Gel electrophoresis and DNA

Electrophoresis enables you to distinguish DNA fragments of different lengths.

DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.

Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.

The use of dyes, fluorescent? tags or radioactive? labels enables the DNA on the gel to be seen after they have been separated. They will appear as bands on the gel.

A DNA marker with fragments of known lengths is usually run through the gel at the same time as the samples.

By comparing the bands of the DNA samples with those from the DNA marker, you can work out the approximate length of the DNA fragments in the samples.

How is gel electrophoresis carried out?

Preparing the gel

Agarose gels? are typically used to visualise fragments of DNA. The concentration of agarose used to make the gel depends on the size of the DNA fragments you are working with.

The higher the agarose concentration, the denser the matrix and vice versa. Smaller fragments of DNA are separated on higher concentrations of agarose whilst larger molecules require a lower concentration of agarose.

To make a gel, agarose powder is mixed with an electrophoresis buffer and heated to a high temperature until all of the agarose powder has melted.

The molten gel is then poured into a gel casting tray and a “comb” is placed at one end to make wells for the sample to be pipetted into.

Once the gel has cooled and solidified (it will now be opaque rather than clear) the comb is removed.

Many people now use pre-made gels.

The gel is then placed into an electrophoresis tank and electrophoresis buffer is poured into the tank until the surface of the gel is covered. The buffer conducts the electric current. The type of buffer used depends on the approximate size of the DNA fragments in the sample.

Preparing the DNA for electrophoresis

A dye is added to the sample of DNA prior to electrophoresis to increase the viscosity of the sample which will prevent it from floating out of the wells and so that the migration of the sample through the gel can be seen.

A DNA marker (also known as a size standard or a DNA ladder) is loaded into the first well of the gel. The fragments in the marker are of a known length so can be used to help approximate the size of the fragments in the samples.

The prepared DNA samples are then pipetted into the remaining wells of the gel.

When this is done the lid is placed on the electrophoresis tank making sure that the orientation of the gel and positive and negative electrodes is correct (we want the DNA to migrate across the gel to the positive end).

Separating the fragments

The electrical current is then turned on so that the negatively charged DNA moves through the gel towards the positive side of the gel.

Shorter lengths of DNA move faster than longer lengths so move further in the time the current is run.

The distance the DNA has migrated in the gel can be judged visually by monitoring the migration of the loading buffer dye.

The electrical current is left on long enough to ensure that the DNA fragments move far enough across the gel to separate them, but not so long that they run off the end of the gel.

The DNA samples are placed in wells at one end of the gel and an electrical current passed across the gel. The negatively-charged DNA moves towards the postive electrode.

Answer:

Its the Ocean.

Explanation:

This is the correct answer I hope this helps you out.

Oceans hold the least amount of carbon compared to glaciers, plants, and soil.  Therefore, option (A) is correct.

Carbon exists in the oceans mainly in the form of dissolved inorganic carbon (DIC) in the form of bicarbonate and carbonate ions. The oceans act as a carbon sink, absorbing around 25% of the carbon dioxide emitted by human activities. However, the amount of carbon stored in the oceans is relatively low compared to other carbon reservoirs such as glaciers, plants, and soil.

Glaciers are made up of compacted snow and ice and can hold large amounts of carbon. Glaciers are important for the carbon cycle as they can sequester carbon for hundreds of years. Plants also store large amounts of carbon in the form of organic matter through the process of photosynthesis. Soil also stores significant amounts of carbon in the form of organic matter.

Overall, while oceans do play a role in the carbon cycle, they hold the least amount of carbon compared to other reservoirs. The carbon cycle is a complex system that involves many reservoirs and processes, and understanding the dynamics of each of these components is crucial to our understanding of global climate change.
