Answer: may exhibit metastasis
Cancer cells may exhibit metastasis, this is true.
<span>Other choices are not true of cancer cells because:
Mitotic rate of cancer is high, not slow. Benign tumors are not cancer. It is distinguishable from normal body cells, it forms neoplasms. </span>
They are called heterotrophs
Organisms that DO use the sun for energy are called autotrophs
Hint: Auto- Automatic- Autotroph (It automatically happens)
Hope this helps you :)
Answer:
Mechanical isolation.
Explanation:
Reproductive isolation may be defined as the behavior and the evolutionary mechanism that are essential for the formation of the speciation. This prevents the fertilization of the unrelated species.
Mechanical isolation is a type of reproductive isolation in which the species are isolated due to the difference in their gametic structure. The deep flower tube has different gametic structure that prevent their mating.Although these flowers are closely related to each other but unable to meet due to the mechanical isolation.
Thus, the answer is mechanical isolation.
I believe it the answer is b, 1
