I think the correct answer from the choices listed above is option A. When crossing-over takes place, chromosomes exchange corresponding segments of DNA. Corresponding genes on non-sister chromatids are exchanged at chiasmata. Hope this answers the question.
Antidiuretic hormone (vasopressin) works at the level of the collecting duct to either increase absorption of water in order to maintain plasma volume and thus blood pressure. <span>This hormone is synthesized by special nerve cells of the hypothalamus and then transported to the pituitary gland where the hormone is released from vesicles into the bloodstream. Vasopressin is released in response to extracellular fluid hypertonicity. His functions are to reabsorb water back into the circulation, from the filtrate in the kidney tubules of the nephrons and to constricts arterioles (raises arterial blood pressure). </span>
Answer:
if you water a plant the water travels though the soil then it will feed the roots and then it will go to the leaves of the plant.
Explanation:
To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

λ

</span>⇒ λ

⇒ λ

⇒ <span>λ</span>
