Answer:
Peripheral membrane proteins (select one):
D) are generally noncovalently bound to membrane lipids.
Explanation:
Peripheral membrane proteins are membrane protenis that adhere only temporarily. These don't penetrate deeply into the lipid bilayer, just penetrate the peripheral regions. Also <em>they are bound to either face of the membrane by noncovalent interactions.</em> There are many different categories of peripheral membrane proteins: Membrane-targeting domains; transporters of small hydrophobic molecules
; electron carriers
; Polypeptide hormones, toxins, and antimicrobial peptides; structural domains; enzymes.

Four times as much genetic material is present in a cell during prophase I compared to a cell that has competed meiosis II. Prophase I is a phase in the first stage of meiosis (meiosis I). During this phase, chromosomes become visible. cross-over occurs, the nucleolus disappears, the meiotic spindle forms and the nuclear envelope disappears. The genetic materials in prophase I divides into two at the end of meiosis I forming tow daughter cells, which then divides again into two at the end of meiosis II forming four daughter cells.
