1. If a red flower (RR) and a white flower (rr) were crossbred, resulting in 100% Rr, what phenotypes would be seen according to
Digiron [165]

Answer: 1) The phenotype of Rr is Pink according to incomplete dominance.

Incomple dominance occurs when none of the alleles is completely dominant over the other, resulting in blending of the phenotype from the parents. When a red (RR) and a white flower (rr) are crossbred, they result in Rr that is a pink phenotype.


2) According to Codominance, the phenotype of Rr is Red and White flower.

Codominance occurs when both the alleles are equally expressed. In this case allele for Red (R) and white (r) phenotype are expressed equally giving Red and White flower.


3) In Codominance, both the alleles are visible in the hybrid and in Incomplete dominance, intermediate (blend of parental) phenotype is visible in the hybrid.

Newton's second law can be demonstrated by which of the following
shutvik [7]

Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.

<h3>What is Newton's second law?</h3>

According to newton second law of motion force is always equal to rate change of momentum.

So, Force basically depend on two factor i.e mass and velocity

In first case if mass is constant and velocity is variable then

Force = mass × acceleration.

And if mass is variable and velocity is constant then it's called thrust force

Thrust force = Rate change of mass × velocity.

S.I unit of mass is Newton.

Therefore, Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.
