Answer:
Biogeographic isolation affects the changes in gene pools that result from which organisms are breeding -is how biogeographic isolation allows for the change of gene pools over ( time )
Explanation:
C. Protons and electrons must be equal as protons have a + charge and electrons are - so they cancel out
Answer:
When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.
Explanation:
Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.
<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.
Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

Chromatin is the component that specifies the nuclear contents during inter-phase.
<u>EXPLANATION:</u>
- The term inter-phase is the type of phase in which the cells would exhibit in all parts of its life.
- Chromatin is a term used to explains the components and contents of the nuclear in its inter-phase.
- A cell grows normally and duplicates its internal structure, the DNA, during inter-phase.
- Then it divides during the phase called mitosis after inter-phase.
