Answer:
C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele
Explanation:
Assuming the black genotype is BB and the brown genotype is bb.
At F1:
BB x bb = All Bb (black)
At F2:
Bb x Bb = BB (black), 2Bb (Black), bb (brown)
Th ratio of black to brown is 3:1
961 black : 317 brown is approximately 3:1.
Hence, the correct option is C.
<em>An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele</em>
Answer;
-Birth rate
Explanation;
-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.
-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.

Answer:
The correct answer is option c. "Ceruminous glands produce a waxy substance which protects the genitals".
Explanation:
It is incorrect that ceruminous glands produce a waxy substance which protects the genitals. The ceruminous glands are not located in the genital area, ceruminous glands are specialized sudoriferous glands located in the the external auditory canal. A normal ear have between 1,000 and 2,000 ceruminous glands, which produce the ear wax that protects this zone.
