Answer no 1 is correct :)
Answer:
No ATP is available to release attached actin and myosin molecules.
Explanation:
Two to six hours later after death, all skeletal muscles of the body become rigid and stiff. This situation is defined as Rigor mortis. It occurs from the lack of ATP along with the production of lactic acid. When breathing stopped permanently in the body, oxygen level also reduced; that’s why body muscles cannot go for any aerobic respiration to produce any ATP.
As we know already, during every muscle construction, ATP needs to break the cross-bridge between Myosin and Actin. So if there is no ATP produced in the body, separation of Myosin molecules from Actin molecules cannot happen anymore. This situation leads for rigor mortis.

Explanation:
The correct answer is probably mammary glands, given that you provided very little context. It is a proven fact that almost every female mammal has mammary glands — and out of the other choices, most organisms do not have lungs, large brains, or placentas.
Answer:
C. The phosphate portions attract water, and the lipid portions repel water
Explanation:
The phosphate parts are polar, meaning they're partially charged, so they attract water molecules, which also have partial charges. The lipids are non-polar, so they don't attract water molecules, meaning they can't dissolve in water.
