Answer:
Basically, Its like a Different version of a gene which are called alleles. Alleles are described as either dominant or recessive depending on their associated traits
Explanation:
Answer:
The correct answer is - higher than
Explanation:
In the lumen of the proximal tubule of the kidney, most of the solutes are absorbed in the form of sodium. There is a gradient of sodium ions which allows the absorption of the solutes from the lumen into the cell.
It is due to the solute or Na concentration is higher in the lumen than Na concentration inside the cells of the tubule wall. So movement of the solutes is due to the concentration gradient.
Answer:
A. True
Explanation:
Hemoglobin is a protein and has two distinct types of polypeptide chains. These are called the alpha and beta subunits. The gene that code for the beta chain undergoes a mutation in a single base that causes sickle cell anemia. Here, adenine base in the genetic code for glutamic acid is substituted with a thymine base.
The genetic code for glutamic acid in the beta chain gene is GAG. The "A" is replaced with "T" and the new code "GTG" codes for valine. Therefore, the mutated hemoglobin has valine in place of glutamic acid. This makes these mutated protein molecules to form aggregates resulting in a change in the shape of RBCs carrying them.
The amino acids<span> in a protein are bonded to </span>each other<span> with peptide bonds - hence the term for a polymer of </span>amino acids<span> is a polypeptide. There are 20 </span>different amino acids<span>, and they all share the same general </span>structure<span>. In the centre of the </span>amino acid<span>is an assymetric carbon atom called the alpha carbon. I hope that you have a good day and i hope this helps you out
