Answer:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Explanation:
Note that the brown eyes is the dominant trait, denoted by B, while blue eyes is the recessive trait, denoted by b. In all cases of the Punnett square, if there is a dominant and recessive trait, the dominant trait will always come out on top.
The given Punnett square:
![\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26B%26b%5C%5CB%26BB%26Bb%5C%5Cb%26Bb%26bb%5Cend%7Barray%7D%5Cright%5D)
Note that there are 3 options (BB, Bb, Bb) respectively, in which there is the dominant trait B (brown eyes). Only in one case is there only the recessive trait b (blue eyes), or a 1/4 chance of obtaining blue eyes. Therefore, there is a 3/4 chance of obtaining a brown eye:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Answer:
osmosis
Explanation:
Osmosis is the net movement of water molecules through a semipermeable membrane. The water molecules are not reabsorbed in the intestines and at the kidney nephrons. Increased osmotic pressure can be caused by inadequate production of vasopressin which regulates the amount of water in the body and the one being lost through kidneys, Thiazide diuretics which increases sodium excretion and kidney disorders
Hyponatremia occurs when the body contains too little sodium amounts due to increased fluid intake making sodium to be is diluted. People suffering from severe vomiting or diarrhea lose sodium due increase fluid intake.

The wolf is the secondary comsumer
Explanation:
Secondary consumers are largely comprised of carnivores that feed on the primary consumers or herbivores. Other members of this group are omnivores that not only feed on primary consumers but also on producers or autotrophs. An example is a fox eating rabbit..
