I need help with these following questions if you could help me I would appreciate it so much.

 

1)In adapting to a parasitic lifestyle, parasites develop extremely fertile reproductive systems.  Why?

2)Endoparasites also have simple sensory systems.  Why?

3)Why does Paragonimus westermanni have such a complex reproductive system and such a huge reproductive potential?

4)Why is it that the developed countries of the world have fewer problems with parasitic diseases than the underdeveloped countries? Consider economics, technology, and the biology of the parasites as part of your answer.

1. In adapting to a parasitic lifestyle, parasites develop extremely fertile reproductive systems.  Why?

Parasites are organisms which require a host to acquire its food and nutrients at the expense of the host. Furthermore, symbiotic relationship with their host is called Parasitism wherein the parasites are getting the benefits of the relationship but the host is harmed. Hence, these parasites needed to develop an extremely fertile reproductive system to easily spread their progenies, infect and reproduce on or within their host to survive because it cannot create food on its own.

2. Endoparasites also have simple sensory systems.  Why?

Endoparasites are parasites which live inside their host. Since the environmental conditions inside the body of the host is relatively constant, the endoparasites developed sensory organs which are highly reduced and simple. This is due to the fact that they do not need a highly complex sensory system inside a host resulting to the loss of unnecessary sense organs.

3. Why does Paragonimus westermanni have such a complex reproductive system and such a huge reproductive potential?

The life span of P. westermanni is dependent on whether or not they can find a host. This is due to the fact that they can only survive within few days in the water unless they can find a host. Hence, they adapted and developed a complex reproductive system wherein they can reproduce through sexual and asexual reproduction at certain stage of its life cycle to augment their reproductive capacity. Furthermore, their reproductive potential is greatly increased because they have intermediate hosts such as snail, crab, dogs, cats and rats wherein they can reproduce asexually and produce many offspring resulting to a huge potential of reproduction.

4. Why is it that the developed countries of the world have fewer problems with parasitic diseases than the underdeveloped countries? Consider economics, technology, and the biology of the parasites as part of your answer.

In terms of economics, underdeveloped countries obviously have numerous reasons as to why they have greater number of parasitic cases in contrast to developed countries. These reasons include poor sanitation, contaminated water, food, soil, poor education, poor sexual hygiene, crowded houses, poor sewage facilities, and poor nutrition, hence, all these factors contributes to the high infectivity rates of these parasites because they thrive in these conditions and gets easily transmitted due to these modes of transmission and conditions.

In terms of technology, undeveloped countries have limited resources in healthcare facilities, equipments, and healthcare workers which results to lesser services given to the people. Therefore, parasitic infections is not screened early on its course of infection and is not treated properly leading to greater chance of spreading the parasites to the community.

Lastly, in terms of biological properties of parasites, they are adapted to reproduce easily in tropical and sub-tropical regions which are mostly underdeveloped countries because these regions are hot and humid which are favorable conditions that suits their reproductive system to infect and spread their offsprings. Furthermore, their vectors and hosts are mostly seen in these regions thereby, greatly increasing their probability of reproduction.
