Explanation:
with the aid of the diagram describe the structure of of synapse and the roles of synapse
Answer:
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. ... In many synapses, the presynaptic part is located on an axon and the postsynaptic part is located on a dendrite or soma.
The function of the synapse is to transfer electric activity (information) from one cell to another. The transfer can be from nerve to nerve (neuro-neuro), or nerve to muscle (neuro-myo). The region between the pre- and postsynaptic membrane is very narrow, only 30-50 nm
Knowing that some individuals from Island 1 colonized Island 2, biologists sample the Mainland and two Island populations fifty years after the colonization events. They determine that allele frequencies are similar on both islands, but they are significantly different than the frequencies of the mainland population. Which of the evolutionary mechanisms could be used to explain these observed
Answer:
The evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time and eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster -bottleneck effect- or because of a population split -founder effect-. In founder effect, a new population originates when a few individuals who are coming from a bigger population carrying its genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and there exists the possibility of developing a peculiar allelic composition. If the number of individuals that originated the new population is low, the founder effect will be very extreme, because the effects of the genetic drift are inversely proportional to the original number of individuals.
In the exposed situation, the evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect. The fact that both islands are similar in their frequencies might be due to little genetic variation on island 1, or because dispersion to island 2 is a recent event on time.
When does transformation occur
Answer:
Transformation results in the genetic alteration of the recipient cell. Exogenous DNA is taken up into the recipient cell from its surroundings through the cell membrane (s). Transformation occurs naturally in some species of bacteria, but it can also be affected by artificial means in other cells.

In 1998 paleoanthropologist Rick Potts of the Smithsonian institution published an article in the yearbook of physical anthropology a peer reviewed Journal the article was titled environmental hypotheses of hominin evolution in his paper pots provided evidence to support his claim that gray variations and environmental conditions over time or responsible for the attacks ability of humans and the success of our species why might this not be the best article to reference?
Answer:
Because the author of the article did not do an experiment to draw his own conclusions and issue his own information, but he did a bibliographic review of the work of other authors to write his own article.
Explanation:
The article presented in the question above was done through a bibliography search and not through an experiment. This means that the author did not test the hypotheses through a scientific experiment, but formulated the conclusions of his article, based on the works of other authors, which makes this article not the best option to be considered as a reference article.

Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.
Answer:
The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter. This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.
The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.

d. Try another metho
Define
Bilateral
Hypoventilation
Hemothorax
Arrhythmias
Answer:
Explanation:
Bilateral symmetry is a type of body symmetry where the body is divided in to halves i.e refers to organisms that have body shapes which look like mirror images along the midline which is called the sagittal plane.
Hypoventilation is a process where little amount of air enter into the alveoli which result in a decrease in the amount of oxygen in the lungs and increase in carbondioxide produced by the lungs. It is caused by too shallow breathing or slow breathing.
Hemothorax is a condition where there is blood build up in the pleural space or chest wall and lungs.
Arrhythmias is a health condition where there is irregular heartbeat. That is the heart may beat to fast, too slow, or irregular heart rhythm.

Myoglobin transfers oxygen obtained from hemoglobin to mitochondrial proteins involved in the catabolism of metabolic fuels to produce energy for the muscle cell. What can you conclude about the structures of these mitochondrial proteins?
Answer:
Explanation:
Mitochondria is a double membrane bound organelle that is located in most eukaryotic organisms and it has a number of different shapes.
A mitochondrion has a outer and inner membranes made up of phospholipid bilayers and proteins which have different properties. Because of the double membraned organization, mitochondria have five distinct parts:
Outer mitochondrial membrane
Intermembrane space which is the space between the outer and inner membranes
Inner mitochondrial membrane,
the cristae space which is formed by the folding in of the inner membrane and
matrix which is the space within the inner membrane.
Mitochondria has a complex structure that allows for all the activities carried out by it this includes,Energy conversion, Pyruvate and the citric acid cycle, NADH and FADH2 which are the electron transport chain, Heat production and Storage of calcium.

explain what would likely happen if there were no shrimp in the close ecosystem
Answer:
It greatly affect population of fish.
Explanation:
If there were no shrimp in the close ecosystem then many fishes die due to lack f food because shrimp is the food of many small and large fishes. They also play a great role in protection of fish's skin by eating parasite, bacteria and fungi present on their skin so it also act as scavengers so if these shrimps are not present many fishes die due to various diseases and the ecosystem would be disturb.
Which of the following terms would be used to indicate a patient is suffering from neuropathic pain?
