3. In pea plants, inflated pods are dominant to constricted pods.Show the cross between a true-breeding inflated pod plant with a
true-breeding constricted pod plant. What are the expected
phenotypes and in what proportion? If two constricted pod plants are crossed what are the expected
phenotypes of the offspring and in what proportion?

Answers

Answer:

Let's consider the alleles for a true- breeding inflated pod to be PP. Let's consider the alleles for the constricted pod to be pp. The punnet square for this can be shown as:

p p

P Pp Pp

The results from the punnet square show that there will be 100% (4:0) inflated pods offsprings produced from this cross. However, their genotype will be heterozygous.

A cross between the constricted pods can be shown as:

p p

p pp pp

The results from this cross show that the offsprings produced will be 100% constricted pod plants.

Climate characterized by mild temperatures is ______. Question 4 options: tropical humid dense temperate

Answers

The correct answer is - temperate.

The temperate climates can simply be described as climates with milder temperatures. These climates have changes of seasons, four of them, spring, summer, autumn, and winter. The springs and autumns tend to have mild temperatures, the summers are warm, and the winters are cold, but the highest and lowest temperatures do not come close to the extremely high temperatures in the tropical zone, or extremely low temperatures in the high latitude zones. So these climates have temperatures that are in between the extremes of the low and high altitudes, thus they are milder climates.

Answers

When you leave the flashlight power on, the beam of its light will grow wider and wider because the individual photon travels though space forever as long as it don’t hit anything. While the beam grows wider, the photons also spread thinner.

RNAi is a technique that silences genes by targeting them and degrading their mRNA. How can this technique be used in scientific laboratories? A. RNAi has been used in laboratories to make bacteria more susceptible to antibiotics, but has limited application in eukaryotic cells.B. RNAi is a powerful tool for degrading mRNA, but because it doesn't degrade other types of RNA, its use is limited.C. RNAi is observed in nature, but it can't be used in laboratories.D. RNAi allows scientists to turn off one gene specifically to study its effect.
