Answer:
Parental genotypes: RrBb, RRBB
Offspring phenotype: Running and black hair
Explanation:
Given, Running (R) is dominant over waltzing (r)
Black hair (B) is dominant over brown hair (b)
Parent 1: Heterozygous running, heterozygous black = RrBb
Parent 2: Homozygous running, homozygous black = RRBB
When they mate ( RrBb X RRBB ) :
Gametes produced by RrBb = RB, Rb, rB, rb
Gametes produced by RRBB = RB
Offspring:
RB Rb rB rb
RB RRBB RRBb RrBB RrBb
All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
<h2>Answer:</h2>
The statement is true if the growth rate is less than death rate. But this statement is false if the growth rate is higher than the death rate.
<h3>Explanation:</h3>
- Growth rate is the division of number of birth and growth of individual with a given time.
- Its unit is individual per second or bigger unit is individual per day.
- Death rate is the number of individuals died in a unit of time.
- When the GR is bigger than DR the population size increase as the many [people will grow than die.
- But when the growth rate is less than death rate, the population size will decline with the passage of time.

The security mirror is a <u>convex mirror</u>.
<h2>
Explanation:</h2>
A convex mirror is a round reflecting surface in which its protruding side faces the wellspring of light. Vehicle manufactures frequently consider fish eyes reflect while different material science writings allude to it as a security mirror.
When a direct light emission is passed on the convex mirror, the mirror will permit the first parallel beams that make up the bar to wander in the wake of striking the intelligent surface.
Since, they have more extensive fields of view than other intelligent surfaces, for example, plane mirrors or inward mirrors, they are usually utilized in vehicle side mirrors.
