Which sequence represents a cross section of the bilayer

Answers

hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head



Answer:

The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.

A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.

The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.  

Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

Which of the following statements accurately describes the relationship between coral reefs and aquatic organisms?a. Aquatic organisms have only a predatory relationship with coral reefs.
b. Coral reefs provide aquatic organisms with resources but derive no benefits in return.
c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
d. Aquatic organisms live independently of coral reefs.

Answers

The correct answer is - c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.

The corals are essential part of the marine ecosystems. They are feeding upon zooplankton, but also their polyps get sugar that is produced by the algae living on them. Also, the corals provide much needed shelter for lots of marine animals, but also are on the menu of some, like the starfish for example.

Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
