The allosteric site is a site that allows molecules to either activate or inhibit (or turn off) enzyme activity. It's different than the active site on an enzyme, where substrates bind

Explanation:

please please helppp meee A mammalogist is studying the behavior of the rain forest jaguar. She spots a jaguar
crouched on a tree branch in the understory, waiting to pounce on a rain forest herbivore
called a tapir. The hair of the jaguar is white with black spots. The jaguar has learned the
habits of this tapir, and he knows it uses this trail each evening. The cat is panting in the
steamy heat to stay cool, and its muscles tense as the tapir approaches. The jaguar pounces
and stabs its prey with long, sharp incisors. Although its meal is large, it will need to hunt
and eat again in a day or two to ward off its hunger.
Compose a four-to five-sentence paragraph that summarizes the general mammal
characteristics you can identify from the details of the story about the jaguar.

Answers

Answer:

The rainforest jaguar, exhibits a well-known mammal characteristic, as it waits for its opportunity to pounce on its prey. Mammals are known to be dominant in its environment, actively seeking its targets. Furthermore, the hairs on the jaguar would be an indicator of its status as a mammal. As mammals are known to have hair, and it is thus a mammal characteristic. They are known to be warm blooded, and one instance in the passage that hints at the jaguar's warm bloodedness would be when it pants in order to stay cool.

Note:

this is really vague lol, since I don't know your teacher's lesson plan, so I'm not sure what mammal characteristics are pointing towards (biological, or behavioral?) so note that this response might not be what your teacher is looking for.

Proteins synthesis is accomplished primarily by the interaction of which two cell structures?

A:vacuoles and mitochondria
B:ribosomes and vacuoles
C:nuclei and ribosomes
D:nuclei and mitochondria

Answers

Answer:

C

Explanation:

Protein synthesis occurs through a chain of processes.

1) transcription of DNA in nucleus to form a RNA strand

2) RNA then undergoes modifications to form a mRNA

3) mRNA then migrates out of nuclear pore and complexes with a small and large ribosomal subunit to form a translational complex

4) translation occurs at the ribosomes to form a polypeptide by joining correct amino acids together through the formation of peptide bonds

5) polypeptide gets modified chemically and folded physically to form a protein in rough endoplasmic recticulum and golgi body.

Protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.

PROTEIN SYNTHESIS:

Protein synthesis is the series of process that involves how proteins are produced by genes. Protein synthesis takes place in two stages namely: transcription and translation.

TRANSCRIPTION:

Genes are stored in the nucleus as DNA, hence, the process of synthesizing mRNA from DNA called transcription, takes place in the nucleus.

TRANSLATION:

Translation is the process whereby mRNA is used to synthesize proteins in the ribosome.

The mRNA, produced in the nucleus of a cell moves to the ribosome, which is the site of protein production.

Therefore, protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.

A. Sympathetic helps the body achieve tension; parasympathetic allows the body to relax.
B. Sympathetic helps the body gain and conserve energy: parasympathetic prepares the body to react.
C. Sympathetic allows the body to relax; parasympathetic helps the
body achieve tension.
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.

Answers

Answer:

D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.

Explanation:

the sympathetic system is your fight or flight response

parasympathetic system is the rest and digest

The statement, that is, the sympathetic prepares the body to react, and parasympathetic helps the body to conserve and gain energy correctly describes the functions of parasympathetic and sympathetic nervous system.

What are the functions of parasympathetic and sympathetic nervous system?

Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system. The sympathetic nervous system is situated close to the lumbar and the thoracic regions in the spinal cord.

Its main role is to instigate the body's flight or fight response. It does this by monitoring the rate of respiration and the rate of the heart. Therefore, it prepares the body to react.

On the other hand, parasympathetic nervous system is situated in between the medulla and the spinal cord, and works to stimulate the body's digest and rest and breed and feed response. Therefore, it helps the body to conserve and gain energy.

Thus, the correct statement is option D.

During the process of condensation, water vapor
a) releases 334 J/g of heat energy
b) releases 2260 J/g of heat energy
c) gains 334 J/g of heat energy
d) gains 2260 J/g of heat energy

I've narrowed it down to a or b, but I wrote the whole question in case I'm wrong-

Answers

Answer:

I actually got releases 2260 J/g of heat energy.

Explanation:

you can determine this by the earth science reference table on the first page , and plus I have the same question.

The process through which the water vapour gets converted into liquid is called condensation. It happens either because of cool air or saturation.

The correct option is:

Option b. releases 2260 J/g of heat energy

This can be explained as:

The amount of heat required for converting 1 mole of liquid into the gaseous state at atmospheric pressure is called the latent heat of vaporization.

The amount of heat released from a mole of vapour when condensed to liquid is called the latent heat of condensation.

During this process, the temperature remains constant and the heat released gets used in the conversion of substance and is called latent.

Therefore, the heat of condensation of water vapour is about 2,260 J/g.

Explain how the Coriolis effect influences the wind direction in your model.

Answers

Answer:

Coriolis effect influences the wind direction.

The Coriolis effect makes the wind to appear and be deflected to either the east or west depending on the direction the wind is moving in either the north or southern hemisphere.

The Coriolis effect makes wind on the northern hemisphere to curve to the right by bending it to counter clockwise direction and that of southern hemisphere curve to the left.

Explanation:

Coriolis effect refers to the pattern of deflection of object in which the northern hemisphere bend to counter clockwise direction and the southern hemisphere to the left.

Coriolis effect is caused by the Earth's rotation.

Answer:

This is the exact answer so maybe re-word it:

If Earth did not rotate, the winds would appear to flow in a straight path. However, because of Earth’s rotation, the winds appear to bend to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Right and left are relative to the wind’s starting location.

Which of the following elements would be the most reactive with other elements?

Multiple Choice

A. boron, #5
B. neon, #10
C. argon, #18
D. helium, #2

Answers

The answer is d helium

The chemical element which would be the most reactive with other elements is: D. helium, #2.

A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following;

Tarnishing.Heat of combustion.Flammability.Acidity.Chemical reactivity.

Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.

Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.

The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.

Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.

In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.
