sashaice [31]

Carbohydrates are your body’s main source of energy. The amount of carbs a man should consume daily depends on his age and activity level. The Institute of Medicine suggests adults to eat at least 130 grams of carbs a day. But If you’re a competitive athlete like Shana, you need additional amount.

Angiotensin-converting enzyme (ACE) inhibitors and other vasodilators are used in the early treatment of heart failure. They act
Iteru [2.4K]

Answer:

Option c. cause pooling of the blood and decreased venous return to the heart

Explanation:

The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.

The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.

Homeostasis has to do with processes that maintain the internal balance within an organism. It can succinctly be defined as the process of regulating an organism's internal environment. The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.

Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.

A retrovirus hijacks a cell's machinery to turn its rna into dna, which is then inserted into the cell's genome so viral protein
Doss [256]
No this virus does not follow the Central Dogma of Biology. The Central Dogma refers to the process involved in cellular replication starting from the replication of DNA, followed by transcription of DNA to RNA, and finally translation of RNA to proteins.

Viruses are special because they hijack cells and use the cell's own mechanisms in order for it replicate. Retroviruses are even more special because they go against the unidirectional flow of the Central Dogma. This is done with the use of their <em>reverse transcriptase.</em>
