On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?
Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

  • abundance of food
  • high fertility rate
  • favorable environmental conditions
  • lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

Q6.7. During many epidemics, health-care professionals emphasize the importance of
Serga [27]

During many epidemics, <u>healthcare </u>professionals emphasize the importance of  community mitigation strategies, such as wearing masks, frequent hand-washing, and social  distancing because these strategies help <u>reduce </u><u>transmission </u><u>even when drug-based treatments and vaccines are  unavailable.</u>

It is of <u>vital </u>importance in cases of epidemics to implement strategies such as:

  • Hand-washing
  • Wearing masks
  • Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to<u> eliminate the presence of a </u><u>pathogen</u> <u>from the surface of your hands</u>, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a <u>final barrier</u> that the pathogen will rarely be able to surpass, given that most pathogens <u>cannot remain airborne over large distances. </u>

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission <u>until vaccines or drug-based treatments become  available and </u><u>herd immunity </u><u>can be reached. </u>
