To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:
R= tall stalk
r= short stalk
The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.
Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.

Answer:
(D) all of the above
Explanation:
The rough endoplasmic reticulum is part of the endoplasmic reticulum, the other one is known as the smoother endoplasmic reticulum. 
1. This rough endoplasmic reticulum is considered rough because it has ribosomes bound to it. 
2. Also, it is part of the membrane system found throughout the cell's cytoplasm, even though its density is considered to be higher in some places, such as near the nucleus.
3. It is also is connected to the nuclear envelope or membrane
Some of its functions include 
1. It produces antibody in certain leukocytes
2. It produces insulin in pancreatic cells
Hence, in this case, the correct answer is Option D "all of the above."
 
        
             
        
        
        
Answer: White Oak
White oak comprises 15% of the commercially available hardwoods in the US. It is a used for structural timbers, flooring, and furniture because<span> of its length (rees average approximately 70 to 80 feet in height), color (White with creamy sapwood and dark gray-brown heartwood) and texture (very strong and hard, and with good steam bending properties). It takes a good finish when machined, nailed and screwed well. </span>
