Methylation is an example of(1 point)
gene mapping
gene editing
epigenetics
DNA replication
Methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.
What is the importance of methylation in the cell?Methylation has many functions, such as in gene expression, where it can turn genes on or off by altering the way that DNA is packaged, such as by tightening or loosening the gene so that enzymes can access it; in DNA stability, methylation can help protect the genome from damage by stabilizing the DNA structure; and in epigenetic regulation, where it plays an important role.
Hence, methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.

autonomic reflexes enable the ans to control what kinds of visceral functions? check all that apply.
Given what we know about the Autonomic Nervous System we can confirm that autonomic reflexes enable the ANS to control functions such as heart rate, urination, and breathing rates.
These are among the many visceral functions that the Autonomic Nervous System controls. As per the pattern that is being established, we can conclude that the Autonomic Nervous System functions at a subconscious level, controlling the visceral functions that do not require conscious thought.
Despite this, some organs can also be controlled consciously, such as the lungs and bladder. Other visceral functions such as heart rate, digestion, and even ocular responses, are not able to be controlled consciously.

Which of the following statements is TRUE?
Carpal tunnel syndrome occurs when the ulnar nerve is compressed.
Carpal tunnel syndrome occurs when the facial nerve is irritated or swollen.
*Carpal tunnel syndrome occurs when the median nerve is compressed.
Carpal tunnel syndrome occurs when the 7th cranial nerve is irritated or swollen.
Answer:
c. Carpal tunnel syndrome occurs when the median nerve is compressed.
Explanation: is correct
Carpal tunnel syndrome occurs when the median nerve is compressed.
What is Carpal tunnel syndrome?When the median nerve, which travels from the forearm into the palm of the hand, is pinched or compressed at the wrist, carpal tunnel syndrome (CTS) develops. The median nerve and the tendons that bend the fingers are housed in the carpal tunnel, a small, stiff passageway made of ligament and bones at the base of the hand. The index, middle, and part of the ring fingers, as well as the palm side of the thumb, are all sensed by the median nerve (although not the little finger). The tunnel can occasionally become smaller and the median nerve can become compressed due to edema or thickening caused by inflamed tendon lining. As a result, the hand and wrist may experience numbness, weakness, or even pain (some people may feel pain in the forearm and arm). The most prevalent and well-known entrapment neuropathy, in which a peripheral nerve of the body is pushed against or crushed, is CTS.To learn more about Carpal tunnel syndrome, refer to

the dart thrower was throwing at the bullseye. what is the best description of this attempt?
Answer:
A. Accurate but not precise
Step-by-step explanation:
The illustration given shows that the was far from each other which means it is not precise because precision is that the given data must be close to each other. However, it is accurate because the darts are closer to the bullseye which can still be considered as accurate. Therefore, I believe this is accurate but not precise.
The best description of this attempt is that the dart thrower is aiming to hit the center of the target.
What is Dart thrower?A person who throws darts at a dartboard is known as a dart thrower. In the game of darts small missiles commonly referred to as darts are thrown at a circular target called a dartboard. Apart from being played in international competitions, the game is commonly played in bars or pubs. Each of the 20 numbered parts on a typical dartboard corresponds to a different score.
The goal of the game is to collect points by throwing darts at the board and hitting special spots to do so. The bullseye, located in the middle of the dartboard, awards the most points when hit. The popular sport and pastime requires precision, concentration and expertise.

O vena cava; aorta; right ventricle; right atrium.
O pulmonary vein; left atrium; left ventricle; aorta.
Answer: pulmonary vein; left atrium; left ventricle; aorta
Explanation: I just did this question in the final exam of A&P and it was correct, hope this helps:)
The basic pattern of blood flow from the lungs to the rest of the body is: pulmonary vein; left atrium; left ventricle; aorta. The option (B) is correct.
What are pulmonary vessels?Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. Your pulmonary veins are part of your body's pulmonary circuit. This is a system of blood vessels that moves blood between your heart and your lungs. This circuit also includes your pulmonary arteries.
For the exchange of gases to occur effectively, the lungs require a dual vascular supply known as pulmonary and systemic circulations. The pulmonary circulation is responsible for bringing deoxygenated blood from the body to the lungs for gaseous exchange and then returning oxygenated blood to the heart.
There are 4 total pulmonary veins—with 2 pulmonary veins coming from each lung, left and right—that empty into the left atrium of the heart.
