- The presence of calcium in the sarcoplasm is directly responsible for exposing the binding sites on actin.
- Rigor mortis occurs after death because detachment of crossbridges does not occur due to the lack of ATP
<h3>What is Sarcoplasm?</h3>
This is defined as the the cytoplasm of striated muscle cells in living organisms .When calcium is present, the binding sites on actin are exposed.
Rigor mortis occurs after death and involves stiffening of the muscle tissue because detachment of cross bridges does not occur due to the lack of ATP.

Answer:
The answer is A.
Explanation:
Since only 1 of the options is wrong, i assume you are looking for that one.
Two types of immunity systems, innate immunity and adaptive immunity. Adaptive immunity is formed when it is exposed to a harmful substance, vaccines for example create adaptive immunity.
Innate immunity is present at birth which consists our skin protects us physically, chemical substances in our blood that protect us from bacteria and infections and also our blood cells such as T cells.
Since innate immunity forms one of the first lines of defense in our immune system and is the first to respond to a threat in a few hours down to as little as minutes, it is not slower than adaptive immunity in its response to infections and pathogens.
I hope this answer helps.

Equilibrium/ Equilibria proposes that once species appear in the fossil record,
the population will be in the state of
little or absent morphologic change. This is called a state of stasis. The
theory further proposes that the population is confined to infrequent and
geographical rapid events when significant evolutionary change happens. The parent species will the split into two
distinct species. This process if called cladogenesis.</span>
