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
Answer:
The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.
Explanation:
Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.
To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.
As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.
Diabetes insipidus is a disease characterized by excessive thirst and the excretion of large amounts of highly diluted urine, which can not be reduced by a reduction in fluid intake.
Diabetes insipidus is due to a deficiency of antidiuretic hormone or insensitivity of the kidneys to this hormone. This hormone causes water reabsorption via action on the distal segment of the nephron during dehydration.
Answer:
Reflected Light
Rays of light reflect, or bounce off objects around us.
<u>Answer</u>: Cystic fibrosis is a genetic disorder that causes thick mucus secretions.
<u>Explanation</u>:
- <em>Cystic fibrosis</em> is a genetic disorder caused by mutations in a gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator).
- The CFTR protein normally functions as a channel for transport of chloride ions in cells responsible for mucus production.
- A person suffering from cystic fibrosis produces abnormal CFTR protein or no CFTR protein at all.
- This is the reason that thick, sticky mucus is produced instead of the thin, watery kind.
