What process is occurring in this picture at B?

Answers

Answer:

Translation

Explanation:

Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.

The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.

Hence, according to this question, the process occuring at B according to this image is TRANSLATION.

what happens to a animal cell placed in a hypotonic solution​

Answers

Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Explanation:

Hypotonic solution is a solution which, contains lesser solute concentration. If animal and plant cells are kept in a hypotonic solution then endosmosis will occur. Endosmosis is a process in which the water molecules move from outside of the cell of lower solute concentration to the inside of the cell of higher solute concentration through the cell membrane or cell wall. Due to endosmosis, both animal and plant cells will swell.

14. Kidneys are filters. As blood passes through the kidney, waste in the form of urine is
left behind. Tubes take the urine from the kidney to a storage bag called the bladder.
What can you conclude about blood leaving the kidney?
A. It moves to the bladder.
B. It has no water left in it.
C. It is ready to be used by the body.
D. It needs to have urine added to it

Answers

Answer:

D. It needs to have urine in it

Explanation:

They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule. The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.

EXPLANATION:

plz can i get brainliest:)

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.

What is corrosion?

The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.

The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.

Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.

Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.

Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

Provide one example of Mutualism.
You must explain: The two organisms, how they both benefit, and any other necessary information to explain their interaction.Immersive Reader

Answers

Answer:

Cattle and egret

Explanation:

Mutualism is a type of symbiotic relationship involving two organisms whose actions cause them to benefit from one another. In other words, both organisms do one another a favour, hence, the relationship is said to be MUTUAL.

- An example of a mutualistic relationship is that of CATTLE AND EGRET. Cattle gets infested by certain parasites like ticks and fleas, which feeds on their blood. Egrets are bird species that flock around cattle to feed on these insect parasites. This relationship is mutual because, egrets help the cattle get rid of their parasite problem (cattle benefits) while the cattle provides food for the egrets when they harbor these parasites on their body (egret benefits).

If the amino acids glycine, alanine and valine were combined in one molecule, what would the molecule be called?

Answers

Answer:

A tripeptide

Explanation:

Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).
