Rigor mortis occurs because ________.

Biology
1 answer:
Kamila [148]3 years ago
6 0

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.

Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.
