Which statements describe examples of facilitated diffusion? a. A kidney cell absorbs water molecules down their concentration gradient using a membrane protein.
b. A neuron allows sodium ions to enter the cell down their concentration gradient using a membrane channel.
c. A neuron moves sodium ions out of the cell against their concentration gradient using a membrane pump and cellular energy.
d. An epithelial cell absorbs amino acids against their concentration gradient using a membrane pump and the energy of another concentration gradient.
e. An inner ear hair cell allows potassium ions to flow down their concentration gradient after sound waves stimulate a membrane protein.
f. A bacterium takes in nitrogen gas directly through its plasma membrane from the atmosphere.

Answers

Answer:

The correct answer is option - A, B, and E.

Explanation:

Facilitated diffusion is a type of the diffusion of facilitated transport the movement of the molecule passively down their concentration gradient which is move in influence of another molecule through the membrane with help of pore or channel made up of the membrane protein.

A kidney cell absorbs water molecules down their concentration gradient using a integral membrane protein.

An inner ear hair cell permits potassium/calcium ions to move, down their concentration gradient after sound waves stimulate a integral membrane protein.

A neuron permits sodium/potassium ions to enter the cell down their concentration gradient using a integral membrane channel.

Thus, the correct answer A, B, and E.

The differences in the sequences in many instances represent a conservative change (such as L for I). c. The differences in the sequences in many

Answers

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin  are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.

Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 375 mL of insulin at a concentration of 40.0 mg/mL . What is the total mass of insulin in the bottle?

Answers

Answer:

Mass of insulin is 15,000mg.

Explanation:

Insulin is the hormone that are released from the beta cells of pancreas that regulates the metabolism of glucose in the body. The improper balance of insulin can cause diabetes in the individuals.

The insulin mass can be calculated by the following formuls:

Mass = volume ×  density.

Mass = 375 × 40

Mass = 15,000 mg.

Thus, the answer is 15,000mg.

Total Mass of Insulin = Volume of Insulin  ×  Concentration of Insulin
                                  = 375 mL  ×  40.0 mg/mL
                                  =  15000 mg
                                  ≈  15 g of Insulin
