I think that the best word to fill into the gap is "solid".

Solid comes in opposition to other fundamental states of matter: liquid, gas, plasma (the last one can be characterized by high electric conductance).

If an enzyme is absent during polypeptide production, a mutation can occur.

Answers

If you are asking if it is a true or false statement, it is a false statement. A mutation cannot possibly occur during polypeptide production or any protein synthesis or process. However, mutation may occur if the protein or enzyme is involved in any DNA replication or transcription process.

When a raw, shell-less egg was placed in sugar solution, the egg shrank. The egg was brought back to its original size by placing it in water. Which process does the experiment demonstrate?

Answers

The process that the experiment in question demonstrates is called Osmosis. It is the process in which a solvent moves from a region of higher concentration to a region of lower concentration through a semi permeable membrane. This way the concentration of the solution in both sides of the membrane becomes equal.

Answer:

osmosis

Which statement describes natural selection? It is the primary mechanism for evolution. It must act on structural traits. It acts to cause overpopulation. It causes learned skills to become heritable traits.

In which part of the nephron are sodium and chloride ions actively reabsorbed?A.
Glomerulus

B. Loop of Henle

C. Bowman's capsule

Answers

Answer:

The correct answer is option C. loop of Henle.

Explanation:

The loop of Henle is the part of a nephron in the kidney, that starts from the proximal convoluted tubule or PCT to the distal convoluted tubule DCT. The major role of the loop of Henle is to build a concentration gradient in the kidney.

Sodium (Na+), chloride (Cl−) and potassium (K+) ions are reabsorbed by secondary active transport from the urine by a Na-K-Cl co-transporter. The electrical gradient and concentration gradient causes more reabsorption of calcium (Ca2+), magnesium (Mg2+) and Na+.

Thus, the correct answer is option C.

Hey there! Here is my answer.

B. Loop Henle
