Answer:
The organisms that thrive at deep-sea vents and seeps have to survive freezing cold, perpetual darkness, high-pressure, and toxic chemicals. For this reason, they are often called "extreme"ex tr em op hi l es for the extreme nature of their living conditions. I don't know
Explanation:
The correct option is C.
Roundworm belongs to the kingdom animalia and to the phylum nematoda. It has round, unsegmented, smooth and thin body which can grow to the maximum of four feet in length. It has a bilateral symmetry. A roundworm has no skeleton and it reproduces sexually.
Answer:
The correct answer is case control study.
Explanation:
A study in which a comparison is made between the patients carrying the disease with the patients not carrying the disease is known as the case-control study. In the mentioned study, the one carrying the disease is termed as cases, and the one that does not possess the disease is termed as controls.
This form of study is generally done to predict the association between the disease and the risk factor. In case-control studies, only observation is done as no attempt is made to change the course of the condition. The prime objective of the study is to predict the exposure of the risk elements for the individuals present in two groups, that is, controls and cases. This form of study is also called case-referent studies or retrospective studies.
The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
<h3>What is population dynamics?</h3>
Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.
Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.
With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
