This disease is cancer.
Cancer is the disease of abnormal cell growth, with the potential of this abnormality spreading to other tissues and other parts of the body.
Firstly the question is incomplete as an option is not there.
Why do the number of organisms in a group change from the first step to the last step of a dichotomous key?
a. The number of organisms decreases because the number of common characteristics of the organisms in a group increases.
b. The number of organisms increases because the number of common characteristics of the organisms in a group increases.
c. The number of organisms is cut in half because the number of common characteristics of the organisms in a group decreases by half in the last step.
d. The number of organisms stays the same because the number of common characteristics of the organisms in a group decreases by half in the last step.
The correct answer is B. The number of organisms increases because the number of common characteristics of the organisms in a group increases.
The most common key for the identification of organisms is a dichotomous key, the number of organisms in a group change from the first step to the last step of a dichotomous key as the no. of organisms increases and forms several groups of species and genus.
<h3>What is the use of the dichotomous key?</h3>
The use of dichotomous keys are :
- contrasting characters
- dividing organisms
- eliminating .
Hence concluded that the dichotomous key has a number of organisms increases because the number of common characteristics of the organisms in a group increases.

According to this problem, this is an example of complete dominance, so the dominant allele would be the allele that codes for physical trait for roundness of the seed.
So the cross would be like this:
W = allele for round seed
w = allele for wrinkled seed
P1 gen = ww • WW
F1 gen = Ww
Since all of the offspring are heterozygous the result is that the dominant allele suppressed the recessive allele for wrinkled seed.
B
explanation : fewer wolves means fewer rabbits eaten so population increases as compared to previous case scenario....
