Please complete the following sentence.

Membrane rafts are

a. depleted in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thicker in the raft domains than in the surrounding membrane.

b. depleted in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thinner in the raft domains than in the surrounding membrane.

c. rich in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thicker in the raft domains than in the surrounding membrane.

d. rich in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thinner in the raft domains than in the surrounding membrane.

c. rich in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thicker in the raft domains than in the surrounding membrane.

Explanation:

Membrane rafts (or lipid rafts) are sections of a celular membrane. They help compartmentalize certain cellular processes.

As the lipid part of its name implies, they are enriched in cholesterol, sphingolipids and GPI-linked proteins. Because it is enriched in such species, it is also thicker than in the surrounding membrane.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
