Expliquer pourquoi les coraux blanchissent

Biology
1 answer:
myrzilka [38]3 years ago
8 0

Answer:

Lorsque les coraux sont stressés par des changements de conditions telles que la température, la lumière ou les nutriments, ils expulsent les algues symbiotiques vivant dans leurs tissus, les faisant devenir complètement blanches. Des températures plus chaudes de l'eau peuvent entraîner un blanchissement des coraux. ... C'est ce qu'on appelle le blanchiment des coraux. Lorsqu'un corail blanchit, il n'est pas mort.

When mendel crossed peas with rr and rr genotypes (where r is dominant and produces wrinkled peas and r is recessive and results
LuckyWell [14K]
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
