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

Some bacteria living in the ocean floor can turn methane (a gas) into food.
Nesterboy [21]

Answer:

Option A

Explanation:

Only an autotrophic species can convert methane into food.  

Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.  

Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.  

Hence these autotrophic bacteria’s will be considered as producers as they produce food.  

Thus, option A is correct.
