The question is incomplete. The complete question is as follows:

Imagine a new type of cell was discovered on Mars in an organism growing in benzene, a nonpolar liquid. The cell had a lipid bilayer made of phospholipids, but its structure was very different from that of our cell membrane.

Describe what might be a possible structure for this new type of membrane.

A. This membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior.

B. This membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior.

C. This membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior.

D. This membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior.

Answer:

D. This membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior.

Explanation:

As per the description of the membrane, the membrane is made up of phospholipid and phospholipid are consist of two hydrophobic tails (non-polar) and one hydrophillic (polar) head.

As the cell membrane is growing in a non-polar liquid, benzene, the non-polar groups or hydrophobic tails will face the nonpolar solvent, as it will repel by the hydrophillic interior and polar head will face the interior of the memebrane.

Hence, the correct answer is D.

What chromosomes are found in body cells but not sex cells?
Leni [432]
None, egg cells don't have chromosomes. No, sex cells do have chromosomes. meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

  • The use of fertility drugs such as Clomiphene (Clomid)

  • Intrauterine insemination (IUI)

  • in vitro fertilization (IVF).

In order to use fertility drugs such as Clomiphene (Clomid) effectively, the procedure include the following:

  • The starting dosage of Clomiphene is 50 milligrams a day for 5 days.

  • The pill should be taken the third, fourth, or fifth day after you start your period.

  • The therapeutic effect of the drug is expected to take place about 7 days after you've taken the last dose.

Vitamin B2 (riboflavin). Helps the body turn food into energy, and protects cells from damage.

Vitamin B3 (niacin). Helps the body turn food into energy and use fats and protein.

Vitamin B6. Keeps the brain and immune system healthy.

Vitamin B12. Keeps nerve and blood cells healthy, and makes DNA -- the genetic material in every cell.

Vitamin C. Protects against infections, builds bones and muscles, and helps wounds heal.

Vitamin D. Helps the body absorb calcium from food, and keeps bones and teeth healthy. Breast-fed babies may need a D supplement.
