Rigor mortis occurs because ________.
Kamila [148]

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.

Flura [38]

The mosquito would become more prone to injury due to a weakening of its Exoskeleton.

Exoskeleton, a hard or flexible covering that supports and shields an animal's soft tissues. The phrase refers to the chitinous integument of arthropods, such as insects, spiders, and crustaceans, and includes the calcareous housings of sessile invertebrates like clams. The exterior waxy, water-resistant covering of the arthropod exoskeleton, which is made from the epidermis, is covered by chitinous, and flexible layers. This coating features tiny breathing openings in terrestrial species (spiracles). The exoskeleton has made it possible for arthropods, particularly insects, to overrun the majority of terrestrial ecosystems by avoiding dehydration. Exoskeletons of animals like the lobster have flexible joints that allow for remarkable mobility.
