Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white
<u>Excessive drinking of water</u> causes hyponatremia.
Hyponatremia is an elementary medical condition that is caused by drinking excessive water. If the concentration of sodium falls below 136 mEq/L, this results in hyponatremia.
Drinking too much water dilutes the sodium in the human body and this results in a high level of water in the body. When the water level rises, cells become enlarged and swollen.
The swelling cells can have harmful impacts on your health by exerting pressure and damaging cell membranes.
Other common causes include diarrhea, liver disease, renal disease, and heart failure. This condition can be cured by taking an IV sodium fluid to raise the degree of sodium.

Answer:
I think the answer would be lichens, because lichens are formed during primary succession as a pioneer species. During secondary succession, grasses are usually the pioneer species.
The term which best describes species C relative to species A is Sister
species. This is as a result of them sharing largest number of derived traits.
<h3>What is Ingroup?</h3>
Ingroup is defined as the group in which organism belongs to. We were
told that A and C are ingroup species.
Species A sharing the largest number of derived traits with species C
means that they have similar traits and a common parent which is a
characteristic of sister species.

Answer:
c. CNS
Explanation:
The Central Nervous System (CNS) is responsible for receiving and transmitting information throughout the body. We can define it with the command center that coordinates the activities of the body. It consists of the brain and spinal cord, which are protected by the skull and spine respectively.
Both structures are reinforced by three connective blades, called meninges. They are: dura mater, arachnoid and pia mater. Between the last two there is a fluid that is responsible for the nutrition of the CNS and the minimization of possible trauma caused by mechanical shocks.
