Which of the following statements regarding model organisms is correct?
a. gregor mendel used pea plant as a model organism for his experiments because it was easy to cultivate and information about the chromosomes was available.
b. caenorhabditis elegans is a multicellular round worm with a short life cycle and the information about the chromosomes is available which allows easy genetic manipulation
c. a model organism should have a fewer offspring's, should have a short generation time and should be responsive to genetic manipulations.
d. according to cdc, 9 out of 10 leading causes of deaths have genetic components involved; therefore a model organism should not be responsive to genetic manipulations and should have longer and stable generation time

The correct answer will be option- C

Explanation:

The model organism is a non-human species organism used extensively in laboratories for genetic studies which acts as an ideal organism to another organism.

The concept of model organism began with the studies of the Gregor Mendel on pea plants and later several other organism like D. melanogaster, C. elegans, Yeast and others were used.

Since the C. elegans is a small roundworm and simple organism whose genome was sequenced in  1998 along with human genome in human genome project, therefore the C. elegans is used as a model which helps manipulation of genes of other genes.

Thus, option-C is the correct answer.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
