Nucleic acid is a substance in which the monomer is a nucleotide. Therefore, option B is correct.
What are nucleic acids?Biopolymers and macromolecules called nucleic acids are important for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base (adenine, guanine, thymine, uracil, and cytosine), a phosphate group, and a 5-carbon sugar.
The components that make up an individual's genetic code are nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid are the principal two examples of nucleic acids (RNA). They have an important role in heredity and protein synthesis.
Thus, A nucleotide serves as the monomer of a material known as nucleic acid. Therefore, option B is correct.

What is another name for the photic, or sunlight, zone of the ocean
Answer:
sunlit zone or the euphotic zone
Explanation:
The highest layer of the world's seas is washed in daylight during the daytime. This brilliant sea layer is known as the sunlit zone or the euphotic zone (euphotic signifies "sufficiently bright" in Greek) or the epipelagic zone (epipelagic signifies "upon the ocean")
(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.
Answer:
The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.
Explanation:
Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria
If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.
When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

using a named examples explain the differences between a specific body defence mechanism and a non- specific body defence mechanism
Answer:
Specific body defence mechanism are resistance that are directed against only one specific invader while,
Non specific defence mechanism protects against any of an enormous range of possible dangers.
Explanation:
NON SPECIFIC DEFENCE MECHANISM are the first lines of general defence, they prevent entry and minimise further passage of microbes and other foreign material into the body. There are five main non specific defence mechanisms, these include:
--> defence at body surface
--> phagocytosis
--> natural antimicrobial substances
--> inflammatory response
--> immunological surveillance
Using PHAGOCYTOSIS as a named example of non specific defence mechanism. This involves phagocytes such as the macrophages and neutrophils which are able to trap any invading microbes either by engulfing them or by extending long pseudopodia towards them which grasp them and reel them in. These cells are NON SELECTIVE in their targets.
SPECIFIC BODY DEFENCE MECHANISM directs its actions against a specific invader. In addition immunological memory develops which confers long term immunity to specific infections. The immunity could be cell mediated or antibody mediated immunity.
Using CELL MEDIATED IMMUNITY as an example, Cytotoxic T-cells directly inactivate any cells carrying antigens. This means they are SELECTIVE in their targets. They attach themselves to the target cell and release powerful toxins, which are very effective because the two cells are so close together. This leads to destruction of abnormal body cells such as infected cells and cancer cells.

Explanation:
Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: increased osmotic pressure in the filtrate that draws plasma through the membrane decreased osmotic pressure in the filtrate that increases the amount of filtration increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration neutral change in osmotic pressure with no effect on filtration
Answer:
The correct answer is ''increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration.''
Explanation:
Osmotic pressure is understood to be the force that must be applied to a solution when the flow of solvent needs to be stopped by means of a membrane with semi-permeable characteristics.Colloidal osmotic pressure in glomerular capillaries: it is the pressure exerted by proteins in the blood, which tends to recover the filtered water. To generate and maintain glomerular filtration, filtration pressure is required. That is, glomerular filtration is a physical phenomenon regulated by hemodynamic changes that affect the glomerulus and, although it is the initial excretion mechanism, it is not the exclusive regulator. Water, ions and some nutrients are mainly reabsorbed in the proximal tubule by different mechanisms. The water will follow a passive transport process by osmotic drag. The activity of the tubule is highly dependent on maintaining a fluid osmotic pressure similar to that of plasma. Since proteins and other elements that participate in the maintenance of the plasma osmotic pressure do not cross the glomerular barrier, in the tubule, the isoosmotic pressure with the plasma is fundamentally conditioned by the content of water and salt (dissociated as chlorine and Na +) of the ultrafiltered.
Cells and transport proteins are physically prevented from passing through the filtration membrane for this the correct answer is to increase osmotic pressure in the glomerular capillaries that reducing the amount of filtration.
Osmotic strain is known to be the pressure that needs to be carried out to an answer whilst the glide of solvent wishes to be stopped with the aid of a membrane with semi-permeable characteristics.Colloidal osmotic strain in glomerular capillaries: it's far the strain exerted with the aid of using proteins withinside the blood, which has a tendency to get better the filtered water. To generate and keep glomerular filtration, a filtration strain is required.What is glomerular filtration?That is, glomerular filtration is a bodily phenomenon regulated with the aid of using hemodynamic modifications that have an effect on the glomerulus and, even though it is the preliminary excretion mechanism, it isn't the different regulator.

How does the aorta compare in size to the other blood vessels near it?
Answer: Its wider and thicker than most blood vessels
Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

Answer:
ver explicacion
Explanation:
La fotosíntesis es el proceso mediante el cual las plantas verdes fabrican su propio alimento en presencia de luz solar, clorofila, dióxido de carbono y agua.
La intensidad de la luz afecta la tasa de fotosíntesis, cuanto mayor es la intensidad de la luz, mayor es la tasa de fotosíntesis y viceversa. Cuando hay una mayor intensidad de luz, hay más luz disponible para impulsar las reacciones de la fotosíntesis.

Explanation:
If the blockage is removed from the blood vessel, what will happen to blood flow after removal?
Answer:
Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, the blood thickens and clumps to form a blood clot in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.
