7. Black fur (B) in pigs is dominate over white fur (b).
Find the probability of a pig in the offspring as
being heterozygous, using parents Bb x BB
a. 0%
b. 25%
C. 50%
d. 75%
e. 100%

C). 50%

Explanation: A cross between Bb and BB will produce four offsprings. Bb x BB = BB, BB, Bb and Bb.

From the result of the above cross, two offsprings are homozygous (BB) while two offsprings are heterozygous (Bb). Being heterozygous means having one dominant allele and one recessive allele.

The probability of an offspring being heterozygous is 2/4 x 100 = 50%. This means that there is 50% chance of an offspring being heterozygous.

materials water oxygen those are the things i can think of in this moment.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
