The possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.
<h3>What do you mean by Genotypes?</h3>
Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for a particular study or interest.
If R represents the dominant allele and a person rolls their tongue having this allele, while the r represents the recessive allele and a person can not roll their tongue having this allele. To roll their tongue, a person needs only one dominant allele. Thus the person could have genotypes of RR or Rr.
Therefore, the possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.

Answer:
1. in animal cell and 3. in plant cell In animals mitochondria transforms energy and chloroplast in plant cell absorb energy from sun light and turns water and carbon dioxide into glucose
Explanation:
1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.
2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
The answer is D MARINE HATCHING
The correct answer is letter D. He has trouble with his balance. This is part of the inner ear that is contains a semi-like fluid inside that is sensitive to movements and motions of the body. Inside these semi-circular canals are hair-like structures that sway or move with the fluids when it detects motion. If there is an imbalance within the membrane, a person may have problems with his balance. A condition that is also known as vertigo.
