Answer:
<u><em>Proteins</em></u><em>:</em> used in facilitate transport across membrane
<u><em>Carbohydrates</em></u>: used to drive cellular respiration
<u><em>Lipid</em></u>: composes the cell membrane
<u><em>Nucleic acid</em></u>: used to create identical daughter cells in mitosis
Explanation:
A. In the cell membrane, transport proteins or channels are present which selectively allow the transfer of molecules. This is why the cell membrane is also known as a selectively permeable membrane.
B. In cellular respiration, which takes place in mitochondria, glucose (carbohydrate) is used to generate ATP molecules.
C. The cell membrane is composed of a lipid bilayer that contains protein channels. This makes the membrane insoluble in water and maintains the integrity of the cell.
D. The nucleic acid is the hereditary material that can replicate and transfer genetic information to the next generation.
The kidney's intrinsic capacity to control blood flow gives the ability to regulate glomerular filtration.

What is renal autoregulation?</h2>
Renal autoregulation is a mechanism that allows the kidneys to maintain constant blood flow and glomerular filtration rate (GFR). This is hugely important to keep homeostasis for several reasons:
- The right blood flow and GFR are necessary for excreting metabolic wastes, which avoids poisoning.
- It is key to maintain the electrolyte balance by finely regulating water and ions reabsorption.
- In case of high arterial pressure, autoregulation protects the glomerular capillaries from suffering an injury.
<h3>Mechanisms involved in renal autoregulation</h3>
Two mechanisms take part in Renal autoregulation:
- Myogenic response: preglomerular arterioles (especially at the level of afferent arterioles) can sense elevations in transmural pressure, which induces their contraction.
- Tubuloglomerular feedback: when the tubular fluid reaches the macula densa located in the distant tubule, the cells on it can detect changes in the concentration of sodium chloride, which is dependent on flow rate, and induce a modification in the diameter of the afferent arteriole.
In conclusion, blood flow and glomerular filtration are two hugely important factors in renal function and both can be regulated by the kidney itself via two mechanisms.

Answer:
adenine, thymine, cytosine and guanine?
Explanation:
The answer is true. They work in conjunction with the bairn endothelial
cells to create a semi-permeable blood-brain
barrier with tight junctions that only allows certain elements to pass into the brain. They achieve this through astrocytic endfeet
in addition to the thick basement membrane.
