Answer:
Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.
Answer:
The correct answer is A) Conformation.
Explanation:
Proton pumps are usually molecules that are able to change its conformation in order to transport molecules from one side to the other. The amino acid sequence cannot be changed, because it would change completely the function of the protein. For example, the sodium/potassium pump changes its conformation in order to move these molecules from one side of the membrane to the other.
<span>The answer is A -The red geranium is heterozygous for red flowers (Rr).
We know that the red flower, to be red needs to have at least a dominant allele, so it could be either Rr or RR.
Let's try both scenarios.
If the white</span><span> geranium (rr) is being crossed with RR, all the offspring would be red with genotype: Rr.
On the other hand, if the flower is Rr and it's being crossed with rr, that would result in </span><span>half of the new generation plants having red flowers and the other half white flowers.</span>
Answer:
Any object that is spherical in shape would best represent a true scale model of the shape of the Earth.
for example: ping pong balls, billiard balls, marble and other smooth spherical objects. The shape of the Earth is called the oblate spheroid.
