The period of Convalescence is the time during which the person regains health and fully recovers.
Explanation:
- Diseases that can spread from one person to other are called infectious disease.
- Disease development is divided into Incubation period, Prodromal period, period of illness, Decline period, and period of Convalescence.
- During incubation period the pathogen enters the host body and starts multiplying itself. But the signs of diseases are unnoticeable.
- Then comes the prodromal period, when the pathogen keeps multiplying itself and some signs of disease are observed but they are not obvious
- After the prodromal period comes the period of illness when the patient exhibits obvious signs of sickness.
- As the period of illness is over the symptoms of disease start to cease and the the number of pathogen decrease in body.This period is the period of decline.
- Finally comes the period of Convalescence when the person returns to his pre-disease state and is completely healthy. (except irreversible damage caused by the disease)
The Sun. It starts off by evaporating, which is done by the sun heating up the water.

Answer:
A. It Shows that organisms have changed over time.
Explanation:
The genotype of the guinea pig that you would want to mate it with the black one is ww, which is also a white guinea pig, as all white guinea pigs must have the genotype ww as w is recessive to b. Also, make sure you know that the black guinea pig should have the genotype of bx, where x is either b or w.
So, if you mate the black guinea pig with the ww guinea pig (white), the offsprings will either be all black, or half black half white.
If the offsprings are all black, you can be sure that the black guinea pig (parent) will have the bb genotype. As each offspring must receive one gene from each parent, so if all the offsprings have black fur, they must have one b gene from the black guinea pig.
On the other hand, if the offsprings are half black half white, the genotype of the black guinea pig (parent) should be bw. This is because in order to have white offsprings, each parent must pass on a w gene so that the offspring would have genotype ww, white.
