Hope this answer correct :)
Neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.
What is nerve impulse transmission?The nerve impulse transmission takes place between two neurons, and then in this way, from the sensory organs, the message passes to the spinal cord and the brain. The synapse is formed between the two neurons, such as the presynaptic neuron that releases the neurotransmitters, and this activates the ligand-gated channel of the postsynaptic neuron. Due to this interaction, the neurons get excited and activated.

Why do oxygen levels drop sharply during eutrophication?
Explanation:
during eutrophication, there is a presence of excess algae in the water body. this causes an excess overconsumption of available organic materials by algae, causing the oxygen levels to reduce rapidly.
When the algae population grows rapidly, it may hinder sunlight from reaching other lifeforms and cause dissolved oxygen levels to fall.
What is eutrophication?Eutrophication is the substantial increase in phosphorus, nitrogen, and other organic material in an ageing aquatic environment such as a lake.
As the amount of organic material that can be subdivided into nutrients increases, so does the efficiency or fertility of such an ecosystem.
When the algae population grows rapidly, it may prevent sunshine from reaching other organisms and cause dissolved oxygen levels to fall.
The primary environmental impacts of eutrophication are an increase in suspended particles caused by extensive macroalgal blooms, a decrease in water clarity, and an increase in precipitation rate, which has resulted in the destruction of benthic habitat due to shading of submerged vegetation.
Thus, this way, oxygen levels drop sharply during eutrophication.

In glycolysis, pyruvate, ATP, and NADH are produced. The lactic acid fermentation process uses the NADH molecule from glycolysis to convert pyruvate into lactate. During lactic acid fermentation, the NADH molecule transfers electrons to the pyruvate molecule and is converted to NAD+. How do you think this transfer of electrons helps the lactic acid fermentation process repeat itself? will give brainliest
Answer:
Explanation:
Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.
The NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.
What is Glycolysis?Glycolysis is defined as the metabolic pathway that converts glucose to pyruvate where the free energy released in this process is used to form the high-energy molecule adenosine triphosphate and the lesser nicotinamide adenine dinucleotide. It is a sequence of ten reactions catalyzed by enzymes.
During glycolysis , ATP and NADH are produced where lactic acid fermentation process uses NADH molecule from glycolysis molecule to convert pyruvate to lactate. During lactic acid fermentation, NADH transfers its electron to pyruvate and is oxidized to NAD+ while pyruvate is reduced to lactate.
NAD+ assisted dehydrogenation and phosphorylation of glyceraldehyde-3-phosphate (G3P) to 1,3-biphosphoglycerate (1,3-BPG) is coupled to lactate production where NADH is supplied to convert pyruvate to lactate, hence, the transfer of electrons helps the lactic acid fermentation process to repeat itself as the reduction of pyruvate to lactate regenerates NAD+ which is reused for uninterrupted operation
Thus, the NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.

When sugar is dissolved into the water, it adds molucules, making the water have a higher concentration. If you have a semipermable membrane between the two, it would create a process called osmosis. The hydrogen bonds would all go to the side with the higher concentration side, also known as the hypertonic side. The side with less bonds would be called the hypotonic side.
Evaluate this statement: Gene flow increases the genetic divergence of populations. Evaluate this statement: Gene flow increases the genetic divergence of populations. This statement is true. This statement is false. Gene flow is not able to influence the genetic divergence of populations. This statement is false. Gene flow reduces the divergence of populations. This statement is false. Gene flow increases the number of genes in populations.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
Explanation:
In biology and related areas, genetic divergence occurs if populations with a common ancestor develop unique traits, which are the result of genetic changes over time. On the other hand, gene flow occurs when traits including genes flow from one population to another, usually because the populations are in contact. In this context, gene flow reduces divergence because if genetic material flows between populations is less likely each population can develop unique traits, instead the populations involved will have similar traits after some time.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
The following information should be considered;
In terms of biology and related areas, genetic divergence arise at the time when the populations are with a common ancestor that created unique traits, due to this there are genetic changes over time. While gene flow arise at the time when traits involved genes flow from one population to another, normally due to the populations are in contact.
