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
In the human body, enzymes function as catalysts to speed up reactions by helping to lower the activation energy needed to start a reaction.
Although some RNA molecules can also act as enzymes, proteins constitute the vast majority of enzymes.
The primary function of enzymes is to decrease the activation energy, or the energy required for a process to start. Enzymes bind to reactant molecules and hold them in place to enable the chemical bond-forming and bond-breaking processes.
The energy of the transition state, which products must pass through in order to become reactants, is reduced by enzymes.
Instead of using energy to move till they collide at random, they might group the reactants together to make it easier for them to interact. They could direct the process along a different pathway with lower activation energy.
By tying them to the active site, they might place the reactants correctly. As a result, the reactants can interact with less energy because they won't have to fight against intermolecular forces that would normally try to separate them.
Temperature, ionic circumstances, and environmental pH all have an impact on how quickly an enzyme.

The answer to this would be a SMALL INTESTINE. The small intestine is the major site for the absorption of nutrients. Nutrients include different vitamins and minerals that are extracted from the foods that we eat. How absorption is possible in this site is the presence of e<span>pithelial cells of the villi. Hope this helps.</span>
Answer:
The correct answer is option d.
Explanation:
An extinct species of australopithecine, that is, Australopithecus africanus was the first species to be illustrated. It was of gracile or slender build and was considered to have been the direct ancestor of modern humans. Like modern man, the A. africanus did stood upright and walked upright, and were having free hands to use. However, they were smaller in height and lighter in weight in comparison to modern man.
