Neurotransmitters are typically stored in which of the following parts of a neuron?
Answer:
Neurotransmitters are synthesized by neurons and are stored in vesicles, which typically are located in the axon ’s terminal end, also known as the presynaptic terminal. The presynaptic terminal is separated from the neuron or muscle or gland cell onto which it impinges by a gap called the synaptic cleft.

Choose the words or phrases that correctly complete the sentence. Two boys are holding onto the ends of a long piece of string, and they move it up and down to make a wave. They begin to move the string faster and faster. When they move the string, the energy (remains the same / increases / decreases) and the frequency (decreases / increases / remains the same). A) increases, increases B) remains the same, remains the same C) decreases, decreases D) increases, decreases
Answer:
The correct answer to the question above is option A "increases, increases"
Explanation:
From the question, the wave discussed is in a string, the wave traveled from one end to the other that makes it a transverse wave because as the string is being moved up and down it creates a disturbance which is at a right angle to the direction of travel. The energy generated by the wave in the string has a relationship with its frequency. Though the waves on a string can be fast once the tension that exists in the string is increased, it is important to note that the lower the frequency of a wave in a string, the lower the energy and that also translates that the tension in the string has also been lowered. So as the string moves faster the frequency and the energy increase.
Consider the following two statements about DNA melting temperature:
1) The melting temperature of a sample of DNA is the temperature at which 50% of the double helices in the sample have completely denatured.
2) A molecule with 53% GC base pairs would have a higher melting temperature than a molecule of equivalent length with 53% AT base pairs.
Determine which one of the statements below is CORRECT.
A. Statement 1) and statement 2) are false.
B. Statement 1) and statement 2) are true.
C. Statement 1) is true; statement 2) is false.
D. Statement 1) is false; statement 2) is true.
Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.
Why is statement 1 false and 2 is true?Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.
Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

what do fossil fuels hold, what kind of energy do they hold, what is converted into, & what kind of energy
Answer:
Explanation: Energy gained from burning fossil fuels is converted to electricity and heat in commercial power plants. When fossil fuels are burned carbon and hydrogen react with oxygen in air to carbon dioxide (CO2) and water (H2O). During this reaction heat is released which further amplifies the reaction.

withdrawal relfex
Explanation:
The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex that aimed to protect the body, stimulated by the presence of damaging stimuli such as heat.
When a person touches a hot object, the heat stimulates temperature and danger receptors in the skin, triggering a sensory impulse that travels to the central nervous system. The sensory neuron then synapses with interneurons that connect to motor neurons. Some of these send motor impulses to the flexors to allow withdrawal.
CELL TRANSPORT: Describe how a large protein and an oxygen molecule will
enter or leave a cell, HINT they do not use the same transport method.
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).
It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytosis. If fluid droplets are taken in, the processes is called pinocytosis.

Cells (A) and (F) show an early and a late stage of the same phase of mitosis. What phase is it?
Answer: (Note: You will find the stages in the attached files)
The phase is PROPHASE. Cell A is in early prophase, while cell F is in late prophase.
Explanation:
The prophase might be divided into early prophase and late prophase.
Early-Prophase: The chromatin is condensed enough to distinguish individual chromosomes. There are also two pares of centrioles located outside the nucleus. They begin the separation from each other, migrating to the opposite poles. The microtubules extend and originate the polar fibers of the mitotic spindle. By this time, nucleoles have already disappeared. In the A cell, you can see the condensing chromatin and the centrioles migrating to the poles, but not there yet. You can also see the intact nuclear membrane and no nucleole. Late-Prophase: The nuclear membrane breaks and disperses. Chromosomes keep condensing until they are completely condensed and in direct contact with the cytoplasm. Each pair of centrosomes is already in the cell poles, and the polar fibers of the mitotic spindle are completely developed, as well as the kinetochore fibers. In the F cell, you can see centrioles in the poles and the noticeable mitotic spindle. You can also see the nuclear membrane broken into many pieces and the chromosomes that are completely condensed.Cell A is at the beginning of prophase, while cell F is at the end of prophase.
We can arrive at this answer as follows:
In cell A, we can see that the chromatin has gone through a strong process of condensation, to the point where we can see the individual chromosomes. This is an intrinsic feature of the beginning of the prophase.Furthermore, the nuclear membrane is still visible in cell A, which is also a characteristic of prophase.In the cell F, we can see the disintegration of the nuclear membrane, the condensation of chromosomes, and the contact of chromosomes with the cytoplasm. This is a characteristic of the end of prophase, where a new phase of the cell cycle will begin.In this cell, it is also possible to see the mitotic spindle and the existence of centrioles at the poles, which is also a characteristic of the end of prophase.You have not shown the picture your question refers to. However, it is possible to find it in questions similar to yours.
