The correct answer is A. Two populations of finches that cannot produce viable offspring
Explanation:
Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.
Answer:
Heart
The
striated muscle tissue with
relatively small cells that have one or two nuclei can be found at the heart. The intracellular calcium signaling is an intrinsic component
of signal transduction pathways that regulate vital aspects of muscle function
including excitability, force production, protein synthesis, and energy
expenditure that occurs in the striated muscle tissue of the heart.
Because we can’t tunnel down, so in order to study the interior layers, we must use indirect methods.
Answer:
From the given information above,
The P value is 0.592. P value is greater than the level of significance.
We do not reject the null hypothesis.
Explanation:
<span>Unused
embryo in the in-vitro-fertilization can be kept frozen until a certain period
of time until couple can decide if they will use it again to try for another
baby. Many couple are having a difficult time of thinking of what to do in
their unused embryo. Some might donate it to infertile couples rather than
thawing it without donating. Letting the unused embryo go is not abortion
because it does not have a life yet, but in abortion the baby is alive in the
womb and the mother tries to remove the baby intentionally. </span>
