What part of a neuron cell relays signals between neurons, or from a neuron to the target tissue?.

Answers

Answer: The correct answer is axon terminal

The part of a neuron cell that relays signals between neurons, or from a neuron to the target tissue, is the synaptic terminal.

What is a synaptic terminal?

The movement of membrane-bound sacs, or synaptic vesicles, toward the presynaptic membrane, is triggered by the arrival of a nerve impulse at the presynaptic terminals. These vesicles fuse with the membrane and release a chemical known as a neurotransmitter.

The nervous system's excitable neuron or nerve cell has a cell body or soma (karyon), dendrites, and an axon. Dendrites are a group of many, short filaments that are in charge of receiving signals.

Therefore, the synaptic terminal is a component of a neuron cell that transmits messages from one neuron to another or from a neuron to the intended tissue.

Secrete acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is –

a. Lysogenic, because the virus is a coronavirus
b. Lytic, because the virus causes respiratory illness
c. Lysogenic, because the virus primarily affects older people
d. Lytic, because of the quick onset of symptoms after infection

Answers

The answer to this question is “d”.

Answer: Lytic, because of the quick onset of symptoms after infection

Explanation: As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

During hearing, the last structure(s) to vibrate, resulting in a nerve signal to the brain, is/are the

Answers

During the hearing, the last structure to vibrate, resulting in a nerve signal to the brain, is the auditory nerve.

What do you mean by Nerve signal?

The nerve signal may be defined as the conduction of impulses that runs along with a nerve fiber from the axons to reach a neighboring neuron.

The process of hearing is initiated with the external projection of the ear which is known as Pinna. Then, the vibration of the sound reaches the tympanic membrane.

Then vibrations enter to middle ear which includes three tiny bones such as malleus, incus, and stapes.

At last, the vibrations reach the inner part of the ear which is known as the Cochlea. This part of the ear surrounds by auditory nerves which play a significant role in the transmission of signals to the brain.

Therefore, during the hearing, the last structure to vibrate, resulting in a nerve signal to the brain, is the Cochlea or the auditory nerve.

Students wanted to perform an experiment to mimic natural selection. They noted that small plants growing in the school garden had projections that extended from the leaves. These projections are called trichomes. They hypothesized that the trichomes protect the plant from herbivory, when herbivores eat the leaves from the plants and cause damage. The students counted the average number of trichomes per leaf and plotted this on the top graph, shown here. They then selected parent plants that had a higher than average trichome number per leaf to pollinate, creating a new generation of plants. The distribution of average trichome number for the second generation is shown in the bottom graph.
Which statements below are supported by the information shown here?
A) The trichome number is controlled by a genetic factor.
B) Directional selection occurred due to the student's experiment.

A decrease in blood pressure, detected by the afferent arteriole, will result in vasodilation. The glomerular blood pressure and the GFR will respond by ______.

Answers

A decrease in blood pressure, detected by the afferent arteriole, will result in vasodilation. The glomerular blood pressure and the GFR will respond by decreasing.

The effects of decreased blood pressure on glomeruli

The glomerular blood pressure is the pressure used to push blood and solutes from the arterioles through the glomerular filter membrane. Therefore it is the blood pressure at the glomerular capillaries.

The glomerular filtration rate (GFR) is the rate at which blood passes through the glomeruli each minute.

The decreased blood volume with its lower blood pressure will go into the afferent arteriole and into the glomerulus, resulting in decreased GFR and glomerular blood pressure.

Therefore, decrease in blood pressure, detected by the afferent arteriole, will result in vasodilation. The glomerular blood pressure and the GFR will respond by decreasing.
