Answer:
<h2>If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs.
</h2>
Explanation:
Red-green color blindness: color blindness is an X-linked recessive disorder. The male having this disease will transmit his X chromosome (with the mutation) to his daughter, who will then be a carrier of the disease.
If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs.
Male inherit its X chromosome only from mother and no X chromosome from father, having one Y chromosome but female receive one X chromosome from father and one from mother, having no Y chromosome, So if the paternal allele is silenced then the males are no affected.
Answer:
Basal meristems
Explanation:
Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.
Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.
This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.

Answer:
Global warming intensifies water cycle
Explanation:
Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.
Answer:
DNA is the blueprint of life because it is what tells our bodies what to make, how to make us , and what to give us.
