The primary succession takes a long time to be done. the secondary succesion takes 200-500 years for completion. the secondary succession occurs in an area which has been denuded recently and lately inhabited. soil is present at the beginning of the secondary succession with some organisms. thank you for this question.
I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms.
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give:
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr
I just did this one if im not mistaken it was red giant
Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
Explanation:
Regular reflection happens when light reflects off an awfully smooth surface and forms a clear picture.
Diffuse reflection happens when light reflects off a unpleasant surface and forms a hazy picture or no picture at all.
