The mutation resulting in sickle cell disease changes one base pair of DNA so that a codon now codes for a different amino acid, making it an example of a missense mutation. Missense mutation is the mutation characterized with <span>changes in one base pair so that the whole amino acid is changed.</span>
This statement is false. <span> The humoral immune system is one part of the immune system that is activated when pathogens are present in the blood stream or other body fluids. B cells are the main cells involved in the response, and these cells secrete antibodies that seek out and attach to pathogenic molecules. These attached antibodies act as markers, marking the pathogens for destruction by other parts of the immune system.</span>
Answer A:
The process of <u><em>photosynthesis</em></u> is occurring in image A.
Photosynthesis can be described as a process by which plants use light energy and convert water and carbon dioxide into sugar and oxygen. The sugar produced is the food for the plants. This process occurs in the leaves where chloroplasts are present. Chloroplasts trap light energy.
Answer B:
<u><em>The organelle is mitochondria. The process which occurs in the mitochondria is cellular respiration.</em></u>
Mitochondria are known as the power house of a cell. The process of cellular respiration occurs in the mitochondria. By this process, glucose and oxygen are converted into carbon dioxide and water. Energy in the form of ATP is released during this process. The energy is used normal cell functions.
Answer:
Carboxylic acid.
Explanation:
Amino acids are made up of the amine group, carboxyl group, hydrogen and R hydrophobic chain. Amino acids are the monomers of the protein and they are coded by the particular codons.
Amino acids contains both the amino group and the carboxyl group. The carboxylic group is a polar group and becomes negative charged when the pH of the solution is greater than the pKa value of the amino acids.
Thus, the answer is carboxylic acid.
