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.

Answer:

Posterior

Explanation:

Posterior refers to the back or rear part of something, while anterior refers to the front part of something.

In the context of the human body, the posterior part is the back side of the body, while the anterior part is the front side of the body. For example, the back of the head is the posterior part of the head, while the front of the head is the anterior part of the head.

Similarly, in the context of the spinal cord, the posterior part is the back part of the cord, while the anterior part is the front part of the cord. The posterior part of the spinal cord contains the spinal tracks that carry sensory information from the body to the brain, while the anterior part of the spinal cord contains motor neurons that control the movement of muscles.

Overall, the terms posterior and anterior are used to describe the relative positions of different parts of the body, with posterior referring to the back part and anterior referring to the front part.

Spinal tracks that go to the brain are located in the posterior part of the spinal cord. The spinal cord is a long, narrow structure that extends from the base of the brain down to the lower back. It is made up of a bundle of nerve fibers that carry signals between the brain and the rest of the body.

The spinal tracks that go to the brain are located in the posterior part of the spinal cord, which is the back part of the cord. These tracks are used to carry sensory information from the body to the brain, as well as motor signals from the brain to the body. The spinal tracks in the posterior part of the spinal cord are organized into different levels, each of which carries signals to and from specific parts of the body.

In contrast, the anterior part of the spinal cord is located at the front of the cord and contains motor neurons that control the movement of muscles. The anterior part of the spinal cord is not directly involved in carrying sensory information to the brain.

Overall, the spinal tracks that go to the brain are located in the posterior part of the spinal cord, not the anterior part.

Explanation:

Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.

A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).

Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.

Answer: Three key parts of the recipe for evolution are variation, selection, and inheritance.

Explanation:

VARIATION:- The first part of the recipe is variation. Variation refers to the differences that exist between individuals within a SPECIES. These variations can be caused byGENETIC MUTATION, environmental factors, or a combination of both. Some variations may be advantageous and provide a better chance of survival, while others may be disadvantageous and decrease the chances of survival.

Selection: The second part of the recipe is selection. Selection refers to the process by which individuals with advantageous variations are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This is known as natural selection, and it is the driving force behind evolution.

Inheritance: The third part of the recipe is inheritance. Inheritance refers to the passing down of genetic traits from one generation to the next. Offspring inherit genetic traits from their parents, including any advantageous variations that their parents may have had.

Answer:

With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).

Explanation:

The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:

From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:

    A + C = G + T

An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:

    A + C = G + T

    5 + 7 = 7 + 5

50 people because the widow's peak is dominant. Those who don't have a widow's peak do not have the gene.

If the gene for the hair pattern "widow's peak" is dominant, it means that individuals with at least one dominant allele will express the trait. We would expect 50 people to be heterozygous (Ww) for the widow's peak trait.

Heterozygous refers to a genetic condition in which an individual possesses two different alleles for a specific gene. Alleles are alternate forms of a gene that can code for different variations of a particular trait. In a heterozygous individual, one allele is dominant and the other is recessive.

The dominant allele is expressed in the phenotype, meaning it determines the physical appearance or characteristic, while the recessive allele remains hidden and does not show in the individual's observable traits. The notation for a heterozygous trait is typically represented by two different letters, one for each allele (e.g., Aa).

Assuming that "W" represents the dominant allele for widow's peak, and "w" represents the recessive allele.

Given that 50 people in the population have a widow's peak (homozygous dominant, WW), we can deduce that the other 50 people must have the genotype for heterozygous (Ww) to express the trait.

The blood (without oxygen) enters the right atrium of the heart through the inferior and superior vena cavas. From the right atrium, it flows to the right ventricle through the tricuspid valve. Then, the right ventricule squeezes when it's full, closing the tricuspid valve and opening the pulmonary valve. The blood then flows through the pulmonary arteries, entering the lungs, where it gets oxygen. The blood will then leave the lungs through the pulmonary veins, entering the left atrium. From the left atrium it flows through the mitral valve, going to the left ventricle. It leaves the left ventricle and leaves the heart through the aortic valve, flowing in the aorta to reach the rest of the body.

Answer:

When someone makes a loud noise and it scares you, your body goes through a series of processes to respond to the sound. I'll break it down using the terms you mentioned.

Explanation:

Sensory organs: These are specialized parts of your body that detect stimuli from the environment. In the case of hearing a loud noise, your ears are the sensory organs responsible for detecting sound waves.

Sensory receptors: These are specialized cells within your sensory organs that convert the stimuli, in this case, sound waves, into electrical signals that can be understood by your body. In your ears, tiny hair cells act as sensory receptors, converting the sound waves into electrical signals.

Central nervous system: This refers to your brain and spinal cord, which are the main components of your central nervous system. Once the sensory receptors in your ears convert the sound waves into electrical signals, these signals travel through nerves to reach your central nervous system.

So, in the situation where someone makes a loud noise, the sound waves are detected by the sensory organs (your ears), which then send the information to the sensory receptors (hair cells). The sensory receptors convert the sound waves into electrical signals, which are then transmitted through nerves to your central nervous system (brain and spinal cord).

Once the electrical signals reach your central nervous system, your brain processes the information and determines that the loud noise is something to be concerned about. It may trigger a response, such as a startled reaction or the feeling of fear. These responses are coordinated by your central nervous system, which sends signals to various parts of your body to react accordingly.

So, the order of the processes involved in how the body processes the sound and reacts to a loud noise is: sensory organs (ears) -> sensory receptors (hair cells) -> central nervous system (brain and spinal cord).

Answer:

A mutation in the N-terminal region may alter protein stability  

Explanation:

Transport proteins are proteins capable of transporting substances through biological membranes. These proteins are located within cellular membranes where they form channels that allow the movement of substances between the internal and external sides of the membrane. The N-terminus is the first region in the protein that emerges from the ribosome during its synthesis. This region is usually composed of signal peptides consisting of about 30 amino acids required for protein delivery. Moreover, the N-terminal region is also important because it dictates protein degradation by peptidases. Consequently, mutations in the N-terminal region of transport proteins can alter the properties of these proteins, i.e., either by modifying protein stability or by altering protein signaling.
