Answer
Chemical elements and water are constantly recycled in the ecosystem through biogeochemical cycles. During the water cycle, water enters the atmosphere by evaporation and transpiration, and water returns to land by precipitation.

Answer:
Is a vicariance event
Explanation:
Even both terms are very similar, there is a difference. A dispersal event occurs when an initial specie travels from one place to another and due to the environmental factors and the adaptation that need to develop to survive will change into different species. In the other hand, the vicariance, is a process in which there is a specie and it lives in a wide are, but it fragments into groups mainly by the continental drift, so with the passing of time it turns into different characteristics, as the human race.
Answer:
A. 50% Type A, 50% Type B
Explanation:
To answer this we can draw a punnett square.
Since o if recessive, it can only be expressed if it is not masked by a dominant allele. Therefore the male with type O blood has the genotype oo. A and B are co-dominant, so the woman has genotype AB.
_ | A | B
o |Ao | Bo
o | Ao | Bo
Since A and B are dominant alleles, they will mask the o allele. Therefore genotype Ao will be a Type A phenotype, and genotype Bo will be a Type B phenotype.
Therefore, the phenotypic probabilities for this cross is 50% Type A, 50% Type B. Hence, the answer is A.

The stress hormones epinephrine and norepinephrine are used by your body to respond to short-term stressors while the stress hormone cortisol provides a more sustained release of energy for prolonged stress.
Epinephrine and norepinephrine are produced by the adrenal medulla during the flight/fight stress response and increase blood pressure, heart rate, and glucose.
<span>The cortisol is steroid hormon with several funstions, one of them is to help the body manage stress</span>
