You need two recessive alleles (xx). If even one dominant allele is present, the dominant trait will show (Xx or XX will both result in the dominant trait showing). That’s why they’re called dominant traits, because they overpower the recessive traits. In order for a recessive trait to show you must have two recessive alleles.

Answer:No, it cannot do any of the seven things it needs to be able to do to count as being alive such as:
Movement - all living things move, even plants
Respiration - getting energy from food
Sensitivity - detecting changes in the surroundings
Growth - all living things grow
Reproduction - making more living things of the same type
Excretion - getting rid of waste
Nutrition - taking in and using food
The car cannot grow or make baby cars. So a car is not alive.
The answer is Rr and rr.
We know:
r - recessive allele
R - dominant allele
RR - dominant homozygote with red eyes
Rr - heterozygote with red eyes (since one dominant allele R can mask recessive allele r)
rr - recessive homozygote with sepia eyes
Heterozygote Rr can give to the offspring either dominant allele R or recessive allele r. Recessive homozygote rr can give to the offspring only recessive allele r (take a look at the uploaded image of Punnett square).
After crossing the parents:
Parents: Rr x rr
Offspring: Rr rr Rr rr
So:
2 out of 4 offspring will be with heterozygous with red eyes Rr: 2/4 = 0.5 = 50%
2 out of 4 offspring will be with homozygous with sepia eyes rr: 2/4 = 0.5 = 50%
Answer:
Volume = 113.112 m³
Explanation:
Given the following data;
Radius = 2 meters
Height = 9 meters
To find the volume of a right circular cylinder;
The volume of a right circular cylinder is calculated by multiplying the area of its circular base with the height of the cylinder.
Mathematically, the volume of a right circular cylinder is given by the formula;
Volume= πr²h
Where;
r is the radius of the circular base.
h is the height of the cylinder.
Substituting the values into the formula, we have;
Volume = 3.142 * (2)² * 9
Volume = 3.142 * 4 * 9
Volume = 113.112 m³
