The dependent variable alters
All the cells don't have all of the intracellular structures because each and every cell do not need each and every intracellular structure. The plant cells have chloroplasts because they need to convert the light energy into chemical energy via the process of photosynthesis, the animal cells, however, have no such need, therefore, the animal cells do not have chloroplasts. Also, the erythrocytes do not have the cellular organelles in them which are present in the other body cells, because there is no need for the cellular organelles in them. The large vacuoles in plant cells is also a great example. The plants need the vacuoles for the metabolic processes, while most animal cells have no need for them.
Adaptation is supported by Darwin's observation of local
variation among tortoises in the Galapagos Islands.
<span>In biology, an </span>adaptation, also called an adaptive trait, is a trait with a
current functional role in the life of an organism that is maintained and
evolved by means of natural selection. Adaptation<span> refers
to both the current state of being </span>adapted<span> and
to the dynamic evolutionary process that leads to the </span>adaptation.
The correct answer between all
the choices given is the second choice or letter B. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
What??? Do you have any more info on this question?
The answer is D. This is an exmaple of incomplete dominance. Red and blue make purple. Because there is no purple alleles, C is false. Because there you can only have 2 alleles total B is false. A is false because having two red alleles makes a red flower.
