The information that directs different polypeptides to fold into different shapes is the order and typee of amino acids (i.e., the primary structure) conatins the information that directs folding.
Polypeptides are made up of two words which are poly which means many and peptide which are the chain of amino acids joined by peptide bond polypeptides are the primary structure of the proteins made by amino acids and by the release of one water molecule from one amine and one hydroxyl group which are NH2 and OH respectively and this primary structure further leads to the formation of secondary tertiary and quarternary structures .
which depends upon the different types of bonding found in them .
which can be hydrogen bonding, van der wall forces, disulfide linkage, ionic bonding, and electrostatic forces and the presence of amino acids in the primary structure further directs the folding of the primary proteins as if cystine amino acid is present in large amount it will form disulfide linkage due to presencee of sulphur in the cystine group and this will lead to formation for quartnery folding,
if amino acids like glycine or arginene are present they will lead to formation pf secondry structures as they will form the hydrogen bonding and also the position of these peimary amino acids determines the direction of folding to form the 3D conformation and the correct folding is very necessary as misfolding can lead to malfunctioning of all the cellular processes happening in the body.

If the connection between the hypothalamus and pituitary were severed, damaging the neurons, the secretion of which type of chemical messenger (signal) would most directly be affected?
If the connection between the hypothalamus and pituitary gland were severed, the releasing hormone would directly be affected.
Releasing hormones are the peptide hormones secreted by the hypothalamus gland to stimulate the pituitary gland. In response to releasing hormones, the pituitary gland releases other hormones like gonadotropin, ACTH, and TSH.
The four types of releasing hormones released by the hypothalamus include:
1. Gonadotropin-releasing hormone (GnRH)
It stimulates the release of follicle-stimulating hormone (FSH) and Luteinizing hormone (LH).
2. Thyrotropin-releasing hormone (TRH)
It stimulates the release of thyroid-stimulating hormone (TSH) and prolactin from the anterior pituitary gland.
3. Growth hormone-releasing hormone (GHRH)
It stimulates the release of growth hormone from the anterior pituitary gland.
4. Corticotropin-releasing hormone (CRH)
It stimulates the release of adrenocorticotropic hormone from the anterior pituitary.
If the neurons connecting the hypothalamus and pituitary gland are damaged, the releasing hormones would be affected. Consequently, the secretion of all of the above hormones would be affected.

The most important trigger for aldosterone release is the renin-angiotensin mechanism, mediated by the renal tubules True or false
The answer is true. The renin-angiotensin mechanism, which is carried out by the renal tubules, is the most significant catalyst for aldosterone release. Extracellular fluid is the term used to describe the fluid that cells store (ECF). Filtrate shouldn't contain blood proteins or blood cells since they are too big to fit through the filtering barrier.

how ocean temperature affects the climate of an area
Answer:
Water's High Specific Heat Capacity
Explanation:
Water is able to absorb large amounts of heat with little to no change in temperature for itself. Therefore, when warm air flows over the ocean, the water absorbs the heat from the air and releases cool air instead. This allows coastal environments to be cooler than other areas.

Why do st. george, ut and salt lake city, ut have different climates?
Salt Lake City seems to be in a distinct state than southern Utah and the majority of the area east of the Wasatch.
In the vicinity of Salt Lake, several quite different geological regions are combined, so if you drive a few hours in any direction, you'll be in a very different region. For instance, if you travel east to Vernal, you'll think you're in a St. George suburb in the far southwest of the state. Even though St. George is over two hours away from Las Vegas, it is essentially a satellite of that city. It is located in a stunning red rock region with fields of black lava stone surrounding dormant volcanoes, canyons, arches, and palm trees. Geologically speaking, rather than merely politically, it seems like another planet. Culturally, anyone from Utah will feel at home in St. George, if they can endure the heat. It is still a very LDS town, but it is still managed by a small group of old-guard families who came here at Brigham Young's request nearly fifty years ago. Growing numbers of people have relocated from Northern Utah to this area, and an increasing number of people who grew up here and are happy to return are doing so now that the local economy is robust enough for them to do so.Learn more about the salt lake city with the help of the given link:

When a big fish swims into an oncoming smaller fish and swallows it, the momentum of the two-fish system remains the same.
In this case, the Law of conservation of momentum principle is used as when a big fish swims into a smaller fish and also swallows it, then there will be no change in the system as the momentum of the two-fish system remains the same.
But when the momentum of the big fish exists in the same condition but since the final momentum is to be true, there arises a combined mass of the big fish as well as the small fish, whereas the case of speed must be reduced.
The Law of conservation of momentum is important as it states that the total momentum that occurred in the initial state of the system remains the same as the momentum that exists in the final state of the system. This conservation principle helps to determine the initial and final velocity of a system that undergoes collision. This collision can be either elastic or inelastic.

Approximately how many atoms thick is a cell membrane, assuming all atoms there average about twice the size of a hydrogen atom?.
There are around 50 atoms in the cell membrane.
Knowing that the thickness of a cell membrane is somewhere between 7.5 and 10 nm will allow you to divide 7.5 and 10 by 0.2 nm, where 1 nm equals 1*109 m.
The cell membrane is roughly 37.5 and 50 atoms thick, according to the two answers of 47.5 and 50.
A hydrogen has a diameter of 10^ -10 m. A cell membrane has a 10^8 m thickness.
The formulae of thickness in terms of number of atoms = d /2 × D
Here the (d) = the diameter of membrane
The (D) = The diameter of hydrogen atom
The diameter of hydrogen atom = 10^-10 m
The thickness of membrane = 10^8 m
by substituting these value in above formulae
The number of atoms = 10^8 /2 × 10 ^−10 m
= 50 atoms
Consequently, the thickness of a cell membrane is equivalent to 50 atoms' total thickness.
