<span>Pepsin is an enzyme that breaks down proteins into amino acids in the stomach (where the pH is 1-3). Pepsin needs to be in an acidic environment to be activated. The optimum temperature is between 30 oC and 40 oC because the average human body temperature is 37 oC. The optimum pH is the acidic one because your stomach has an acidic pH.</span>
Upon crossing BB with bb, we will get a hybrid of Bb.
- Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
- The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
- (a) Genotype of blue scales fish will be BB.
- (b) Genotype of blue scales fish will be bb.
- (c) Genotype of blue scales fish will be Bb.
So, in this case B and b alleles will express equally.

Translation happens between the two sub units of ribosomes.....as there the RNA converts into amino acid ! because RNA is read by tRNA and only in ribosomes!
Answer: Elephants
Explanation:
Elephants have being able to survive in the savannah due to its ability to adapt. Elephants natural have no sweet glands so they have to device other means to cool their selfs, th ey achieve this by flapping their ears to create the cooling effects they need to survive in their environment. They also posses tusk and long trunks which they used for eating and drinking. The adaptation of the elephants to the African savannah has being due to the effects of environment and the genes. A popular example is an African elephant is different from it’s counterpart from Asia. Africa elephants have bigger ears unlike Asians which are smaller
