How the chromosomes aligned on the metaphase plate during meiosis
The correct answer is option B, that is, the release of calcium ions makes actin and myosin to combine with each other.
At the time of the stimulation for a muscle contraction, calcium is discharged into the fiber. It combines with troponin and instigates it to move tropomyosin, exposing the binding site for the myosin cross-bridge. Thus, the face of the actin filament is now free to combine with myosin heads to initiate contraction of the muscle.
Answer:
B
Explanation:
a cell does NOT destroy energy
According to statistics it is
Failure to ID a target a.k.a accidentely shooting someone who was misconcieved as a deer
and
Failure to maintain a safe zone of fire a.k.a If you miss a steer it will attack you in self defense
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
Hope this helps.
