Hey there mate!
I know that the farther you go back, the more that the ancestors would most likely have no resemblance and it would even look like they don't look like each other. There would be basically (unrelated) from one another.
So, based from your options listed above, I believe that the correct answer to this question would be (<span>animals descended from one ancestor)</span><span>.
I hope this would help you!</span>
Answer:
r-selected
Explanation:
R-selected species are organisms The carrying capacity is not a limiting factor. The life span of these individuals is short and in general there is no care with the offspring. They aim to exploit empty niches and produce a large number of offspring each cycle, even though few of them survive to adulthood. Informally it can be said that this is a strategy based on quantity rather than quality. Examples of r-selected species: insects and most fish.
Structure and function-there are only TWO types of cells-prokaryotic and eukaryotic
If<span> the </span>original<span> organism decays, leaving an imprint and an empty </span>space<span>, it is </span>called<span>an exterior mold or simply a mold. </span>If a space in the structure is filled with minerals and then the original animal or plant part dissolves<span>, it is </span>called<span> a cast.</span>
