Explanation:

The antidiuretic hormone (ADH), also known as arginine vasopressin (AVP), or argipressin, is a hormone produced in the hypothalamus that is stored and released through the neurohypophysis present in most mammals, including humans. Vasopressin is a peptide hormone that controls the reabsorption of water molecules by concentrating urine and reducing its volume, in the renal tubules, thus affecting tubular permeability. Vasopressin is released primarily in response to changes in serum osmolarity or blood volume increasing peripheral vascular resistance and in turn blood pressure. It receives its name because it plays a key role as a homeostatic regulator of fluids, glucose and salts in the blood.

It is a small hormone (oligopeptide) consisting of nine amino acids:

NH2-Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-COOH

Vasopressin is a peptide hormone produced by the hypothalamus (supraoptic and paraventricular nuclei), but stored and secreted by the pituitary gland. Most are stored in the back of the pituitary gland (neurohypophysis) in order to be released into the blood. Vasopressin is in high concentrations in the locus coeruleus and in the black substance, which are catecholaminergic nuclei.

Answer:

Angiotensin II atrial natriuretic peptide(ANP) lowers blood pressure.

Explanation:

Increase in plasma volume leads to increase in blood pressure and a decrease in plasma level also leads to a decrease in the blood pressure. ANP is an enzyme which stimulates the decrease in blood levels through certain factors thereby causing a decrease in the blood pressure.

Meanwhile ADH stimulates increase in blood plasma levels thereby increasing the blood pressure.

An insect with coloration to avoid being detected by a predator would be an example of.
Vilka [71]

An insect with coloration to prevent from being detected by a predator would be an example of Camouflage.

<h3>What is the importance of Camouflage?</h3>

Camouflage, commonly characterized as cryptic coloring, is a defensive tactic used by organisms to obscure their appearance, generally in order to blend in with their environment.

Camouflage is utilized by organisms to hide their location, identity, and movement. This enables prey to evade predators while also allowing predators to sneak up on victims.

An insect with coloration to avoid being detected by a predator would be an example of Camouflage.

Thus, the correct answer is Camouflage.

9. Which structure helps animal cells maintain their shape?
ludmilkaskok [199]

Answer:

<em><u>D. Cytoskeleton</u></em>

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work.  So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.

Which statement describes what happens with ATP during glycolysis?
Alecsey [184]
Glycolysis requires an investment of 2 ATP, but it yields a total of 4 ATP, netting 2 ATP. So more ATP is produced than is used.

Which is a mechanism for restricting the movement of proteins in the plasma membrane? Choose one or more:
alexgriva [62]

Answer:

The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"

Explanation:

According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:

A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.

B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.

C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.

D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.

E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.
