Predator and pretty in marine ecosystems close to shore
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.
Because we know that 15% of the population does not have the allele we can assume that at least 85% of the population has at least on copy of the dominant allele.
Sieve tube member cells are living cells, have companion cells and are typical for gymnosperms.
Tracheids have secondary cells walls and are functioning like dead tubes that enable the flow of water through the plant. Tracheid occurs in vascular plants, both angiosperms, and gymnosperms.
The parachutes are the subject of the study and different types, or brands, of them should be used.
