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)

Raoul practiced a skill for 30 seconds and then rested for 5-seconds between trials. Scarlett practiced the same skill for 30 se
zalisa [80]

Answer:

The correct answer is option B. "Raoul's practice is massed; Scarlett's is distributed".

Explanation:

A massed practice condition is defined as a task that its performed by an individual without taking a significant amount of rest. Since Raoul is only taking 5 seconds of rest between trials, his practice is massed. On the other hand, distributed practice conditions involve resting for longer periods of time. Scarlett is resting 40 seconds between trials, which represents a longer period of time that the trial itself (30 seconds), therefore her practice is distributed.

Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.​
Tema [17]

Answer:

It depends on the fish (I do not see any pictures) Any fish is an example of natural selection.

Explanation:

A good example would be that polar bears grew and evolved to have white fur to blend in the snow to sneak upon prey. However, their brown bear counterparts failed to do that. So due to better camouflage and hunting technique, the polar bears survived more up north.
