There will be 0 sister chromatids would that cell contain during G1 of the cell cycle. Chromatids in biology is defined as each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.

Answer - A negative feedback loop.
When one is exposed to higher temperatures, the body starts regulating its own temperature by the process of negative feedback loop. In response to higher external temperatures one starts sweating, and this results in lowering of the internal temperature and cooling down of the body.
Answer:
1 out of 4
or
25%
Explanation:
First we draw a Punnett Square for this:
R r
R RR Rr
r Rr rr
So here we have the following genotypes possible for this cross:
RR = homozygous dominant
Rr = heterozygous dominant
rr = homozygous recessive
As you can see out of the four (4) possible outcomes, one (1) of them is rr. So the probability is 1 out of 4 chances or 25%.
