Answer:
the first one is the answer from my research
Explanation:
<u>Answer</u>: The energy source that generates wind is actually the sun.
<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.
Answer:
The correct answer is - option B. They are small because they lack a nucleus.
Explanation:
Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.
In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.
Thus, the correct answer is : option B. They are small because they lack a nucleus.
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. The genus Gorilla is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after the chimpanzees and bonobos.
