The allele for round seeds is represented by R. Suppose that a pea inherited two recessive alleles for wrinkled seeds. For wrinkled seeds, it would be rr.
In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive, Under the following conditions would we observe wrinkled seeds in a pea plant: When the plant inherits a recessive allele from both parents.
In pea plants the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive.
The plant with round seeds would have genotype RR.
The plant with genotype rr would have wrinkled seeds.
As we know that the recessive allele is only expressed when there is no dominant allele present so,
RR is dominant as both alleles are dominant
Rr is a heterozygous condition where one dominant allele comes from one parent and one recessive allele comes from another parent.
rr is possible which is wrinkled seed shape, only if each parent plant contributes one recessive allele.
Therefore, The allele for round seeds is represented by R. Suppose that a pea inherited two recessive alleles for wrinkled seeds. For wrinkled seeds, it would be rr.

How is a runner's speed affected by wind?
A tailwind will boost up the speed of the runner while a headwind will slow the runner down.
A tailwind is a wind that is blowing along the direction of the runner approaching. Whereas a headwind is the wind that blows opposite to the runners approach.
This happens because the body is actually running flat to the wind which gives a resistance to the wind flow. So the wind actually pushes the body forward or backward. If the wind is coming from back, the wind pushes the athlete towards front, increasing his speed by a few miles per hour. When the wind is coming from front, the wind is actually pushing the athlete backwards, which decreases the speed.
The wind also makes it difficult for the athlete to breathe, thereby decreasing the speed to a certain extent in general.
Answer:
I would set up the wind machine so it was blowing against people running. I would have it blow at different speeds in different trials. I would use a stopwatch to record the time of each trial for the runners. I would use the computer to help analyze the data from the trials.

Answer:
The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.
