It is not surprising that alcohol relaxes people. Thus, the correct option for this question is B. This is because it binds to neurons that normally receive the neurotransmitter GABA.

What are Neurotransmitters?

Neurotransmitters may be characterized as the types of chemical substances that are released by the transmission of nerve impulses through the synapse. These chemical substances are present within the synaptic cleft.

Under the influence of these chemical substances, the post-synaptic surface becomes depolarised resulting in a nerve impulse in the post-synaptic neuron. The same action is influenced by the alcohol that relaxes people through the liberation of neurotransmitters known as GABA.

Therefore, it is not surprising that alcohol relaxes people. Thus, the correct option for this question is B.

does The replication of DNA occur during anaphase?

Answers

To answer this question we need to remember a little of the cell cycle and the cell division process. When cell division starts (Prophase) the DNA condensates and forms chromosomes, at this point DNA, has to be already duplicated because when acquires a condensed form it can't be replicated or transcribed. Therefore replication occurs before, this is during the S phase (synthesis) of the cell cycle, previous to any phase of mitosis and meiosis.

Answer:

No, the replication of DNA does not occur during anaphase. DNA replication occurs during the synthetic phase (S phase) of the Interphase.

Analyze the graph showing the rate of photosynthesis activity as a function of carbon dioxide level. Select as many of the choices below
that accurately describe the shape of the graph as it relates to photosynthesis.
Rate of photosynthesis
Carbon dioxide
concentration
Carbon dioxide is not needed for the Calvin cycle, so the graph levels off after a certain point
The rate of photosynthesis increases as carbon dioxide levels increase.

Answers

In the photosynthesis graph, the rate of photosynthesis increases as carbon dioxide levels rise.

What is photosynthesis ?Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy. Photosynthesis is the conversion of light energy by phototrophs into chemical energy, which is then used to power cellular activities. Sugars, which are formed from water and carbon dioxide, are used to store chemical energy. Photosynthesis occurs within the chloroplasts found in the mesophyll of the leaves.

In glycolysis, a glucose molecule is split into two molecules of ______, and energy is harvested as atp and nadh.

Answers

In glycolysis, a glucose molecule is split into two molecules of pyruvate and energy is harvested as ATP and NADH.

The process of glycolysis is the first stage of cellular respiration. Cellular respiration is the process through which glucose and oxygen react to produce energy in the form of ATP as well as NADH for the cells to function.

During the process of glycolysis, the glucose molecule is broken down. Energy is released by this breaking down of glucose. The glucose breaks into two pyruvate molecules.

The process of glycolysis occurs in the cytosol of a cell and it is a complex process with a series of steps.
