Punctuated equilibrium has been a theory in evolutionary biology developed and coined by Stephen Jay Gould which talks about very rapid changes which occur in nature while on the other hand still having a lot of stable periods with plenty of change in general.
The correct answer for that reason would be B.
Answer: the number of cells increases
Explanation:
The changes experienced by a human, from birth to 16 years old in form of growth is facilitated by the increase in the number of cells.
Most tissues in the human body grow by increasing their cell number, but this growth is being monitored and regulated to maintain a balance between the different tissues.
<span>When Prophase is occur, during this stage, changes occur both in the cytoplasm and in the nucleus. Within the nucleus, the chromatin fibers become more tightly coiled and folded, forming discrete chromosomes that can be seen with the light microscope. The nucleoli disappear. Each duplicated chromosome appears as two sister chromatids joined together, with a narrow waist at the centromere.In the cytoplasm, the mitotic spindle begins to form as microtubules rapidly grow out from the centrosomes which begin to move away from each other.</span>
Answer: Geography affects solar energy potential because areas that are closer to the equator have a greater amount of solar radiation.
Explanation: However, the use of photovoltaics that can follow the position of the Sun can significantly increase the solar energy potential in areas that are farther from the equator.
