After crossing over of peonies, one with purple flowers and long stems, and the other with white flowers and short stems we will get the number of offspring 83 with purple flowers and short stems; 29 with purple flowers and long stems; 26 with white flowers and short stems; and 9 with white flowers and long stems.

A dominant allele is one that nullifies the effects of a recessive allele. The allele that is covered up by the dominant allele is known as a recessive allele.

This shows that a plant with purple flowers and long stems is carrying a dominant allele that masks the effect of the recessive allele in a plant with white flowers and short stems.

grandymaker [24]

Answer:

true

Explanation:

When your eyes are not covered and you are in an area with good lighting, then opening your eyes would certainly be a necessary thing to do to be able to see and this makes your vision to be normal.

According to Leo Gross, you can have a normal vision if you are 20 feet away from a particular spot and you see what a normal person sees on that same spot. There is the Snellen chart one is also expected to read in that position, so maintaining a normal vision means someone has 20/20 vision.

Imagine that you are outside on a cold day and have removed your gloves to answer your phone. Which statement is true regarding
Klio2033 [76]

Answer:

The correct answer will be option-C

Explanation:

Mammals are warm-blooded animals that are they need to maintain the internal temperature irrespective of the external temperature at a constant rate or 37° C.

In cold conditions the person exposing the body parts to cold conditions response either by producing heat or conserving the heat in the body.

If a person removes the gloves, then a physiological change leads to the change in the diameter of the blood vessels. The diameter of the blood vessels reduces which reduces the loss of heat from the body as constriction of the blood vessels decreases the surface area to be exposed to cold conditions.

Thus, Option-C is the correct answer.

Most cells cannot harness heat to perform work because
Daniel [21]

Answer:

Temperature is usually uniform throughout a cell (Ans. C)

Explanation:

Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.

Heat is a type of energy which is transfer from one body to another body due to the temperature difference.

It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.
