A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

C (Gene Mutation)

Explanation:

Edge. 2020

Genetic mutation is most likely to cause differences in the population. Therefore, option "C" is correct.

A prominent change in the sequence of the DNA is known as a genetic mutation. Mutation can be useful and nonsense. Mutation can alter the function of the DNA gene. To understand the genetic mutations, the sequence of the DNA should be known.

The types of genetic mutations are frameshift mutation, insertion and deletion mutation, translocation mutation, and substitution mutation. Albinism can be genetically transferred to the offspring. Both parents should carry the gene responsible for the albinism in oculocutaneous albinism.

Therefore, Albinism occurs when both parents contribute homozygous genes to offspring.

As a population ecologist, one would recommend that state officials intervene and limit the deer population through a combination of hunting and relocation programs because the starvation indicates that the population has exceeded the carrying capacity of the environment.

The population ecologist maintains the different populations and studies them, and in the deer population, the hunting and relocation programs can be designed to target specific age and sex classes of deer, allowing for the maintenance of a healthy and sustainable population.

Hence, as a population ecologist, one would recommend that state officials intervene and limit the deer population through a combination of hunting and relocation programs because the starvation indicates that the population has exceeded the carrying capacity of the environment.

The components responsible for providing the genetic code that determines how proteins are built and, therefore, they determine traits are the nitrogen bases of nucleotides in the DNA molecule.

Nitrogen bases of nucleotides in the DNA molecule are small subunits of these building blocks of the genetic material. In DNA, a nucleotide is composed of three different subunits which are the nitrogen bases, the sugar ribose and a phosphate group.

There are four types of nitrogen bases which are called adenine or A, guanine or G, cytosine or C, and thymine of T.

Therefore, with this data, we can see that nitrogen bases of nucleotides in the DNA molecule are four (A, C, G and T) and they are building blocks of the nucleotides that form the genetic material of an organism cell.

More than one gene may contribute to a genetic trait.

Polygenic Character

A trait that is influenced by two or more genes, such as height or skin tone, is referred to as a polygenic trait. Polygenic traits do not follow the laws of Mendelian inheritance since several genes are involved.

Multifactorial traits are many polygenic qualities that are additionally influenced by the environment.

Multigenic trait We've discovered that the genetic component of many of the most significant health conditions of our time, such as cancer, heart disease, and diabetes, is caused by the interactions of many different genes as we've gotten better at identifying regions of the human genome that are associated with disease and at analyzing complex genomic data. Thus, polygenic, or having numerous genes. Studying these problems has been exciting since it has revealed how much may be done to improve human health by using the methods currently available to forecast the hazards associated with polygenic features.

Answer:

Explanation:

The best summary of the outcome of Redi's experiment is that the experiment provided evidence against spontaneous generation by demonstrating that maggots do not spontaneously generate from decaying meat when it is isolated from flies.

Francesco Redi conducted an experiment in the 17th century to challenge the prevailing belief in spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter.

In his experiment, Redi set up two groups of jars containing meat. One group was covered with gauze to prevent flies from accessing the meat, while the other group was left uncovered.

Over time, Redi observed that maggots appeared only in the uncovered jars where flies had access to the meat, while the covered jars remained free of maggots.

This led Redi to conclude that maggots were the offspring of flies and did not arise spontaneously from the meat.

His experiment provided empirical evidence against the theory of spontaneous generation and contributed to the development of the concept of biogenesis, which states that living organisms come from pre-existing living organisms.

Plasmids of the bacterium Agrobacterium is useful for introducing genes into plants.

Agrobacterium is a type of bacteria that will cause tumors in plants, it does this by transferring DNA to plant cells. This will cause the well-known 'neck gall disease', this is because it will cause tumors on the neck of the plants.

Scientists have been able to use this to create transgenic plants, using plasmids, this was easy for them since plasmids are easy to manipulate. They used the endonucleates to be able to replicate the genes of interest.
