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)

Answer:

Adaptations to a common environment and examples of convergent evolution

Explanation:  

Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.  

Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.  

In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
