Answer:
Phloem and xylem are closely associated and are usually found right next to one another. One xylem and one phloem are known as a ‘vascular bundle’ and most plants have multiple vascular bundles running the length of their leaves, stems, and roots.
Answer:
(A)
Explanation:
In question number one, it is important to understand that during exercise, the oxygen hemoglobin dissociation curve shifts to the right. This is also confirmed by the fact that the patient, Kira is also breathing slowly. CO2 builds up in the both as patients begin to hypo ventilating. Most likely this patient in in a state of respiratory acidosis. But, it is important to understand that when the curve shifts to the right in this situation, you have decrease affinity of Hb for O2, meaning that the O2 does not want to bind to the hemoglobin. It instead is gonna wanna go straight to the tissues so that the tissues can get oxygen during high exercise states like this one. If the tissues don't get oxygen then you would have elevated lactic acid production in the tissue and the body would go into a sever state of lactic acidosis. So during excercise and increased CO2 content in the blood due to hypoventilation post excercise, our body's natural mechanism is to dump all the oxygen we get directly to our tissues and bypass the hemoglobin that is circulating in our vessels. So that being said you should be able to answer the question above. The hemoglobin would be less saturated with o2 in this case.

Where a lot of vegetation is current
well its not A, bc humidity has something to do with it. and its not B, bc wind doesn't have anything to do with it. so it might be C or D
Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>
