A community for different living organisms that support each other is called an ecosystem. The answer is (A) an ecosystem.
The answer is B. I hope it helps.
If biodiversity is lost in an ecosystem, it will lead to decrease in ecosystem resilience. Biodiversity loss is a major concern now. With the extinction of many species, ecosystem might collapse. Removing a single species can result in a partial collapse of the ecosystem. For example: honey bee colony collapse situation. Without honey bees, humans would struggle or fail to grow certain important crops. With more loss of biodiversity it may become hard for our very survival also.
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.
