Which of the following statements about the development of infectious diseases is correct?
zalisa [80]

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)

Shtirlitz [24]

Full question:

Drag each label to the correct location on the chart. Based on the number of offsprings they produce at one time, organisms are classified into two categories many offsprings at once and a few at a time. Sort the characteristics based on the category they describe.

A.Low percentage of offspring reach adulthood,

B.limited parental involvement,

C.High percentage of offspring reach adulthood,

D.Rapid maturation,

E.Parental care observed,

few offspring at once vs many offspring at once.

Answer:

At the same time, there are a few offspring

C. A high proportion of offspring grow up to be adults.

E. Observed parental care,

At the same time, many offspring

A. Only a small fraction of offspring grow up to be adults.

B. minimal parental participation;

D. Rapid maturation.

Few offspring at a time have a high percentage of offspring reaching adulthood. If a large percentage of offspring reach adulthood, the offspring are likely to be few and well cared for.

<h3>What is parental care?</h3>

Parental care is seen to be unique to only a few offspring at a time. If the parents provide good care to their children, the offspring are likely to be few. It will be easier for the parent organism to care for a small number of children at once.

Many offspring at once have a low percentage of offspring reaching adulthood. Because there are so many kids at once, competition for room and food, as well as a lack of care, only a small percentage of them will reach adulthood.

Many offspring have limited parental participation at the same time. Because there were so many kids at the same time, the competition for parental care among the offspring would be strong. The parents' organism will be unable to care for the large number of children.

Rapid maturation is unique to several offspring at the same time. In order to survive, the organism will have to mature quickly. Due to the large number of children, survival will be determined by the fittest. The ability of the children to mature quickly will be aided by the survival of the fittest trait.
