Answer:
The correct option is;
A. Antibodies
Explanation:
A Specific immune response or organ specific immune response are initiated by antigens within a particular organ. Pathogens carry specific antigens on their surfaces which are responded to by the body immune system by the production of cells to tackle the pathogen or the body produces antibodies which aid in the neutralization of the pathogen
Non specific immune response also known as innate immunity are the immune response that come with us from birth such that they form the initial or first line of defense to protect us from all antigens
Examples of non specific immune response are;
Stomach acid
Respiratory cilia
Increased mucus
Therefore, the correct option is A. Antibodies.
Answer:
The opposite of this process is called deposition
Explanation:
Example is conversion of NAD+ to NADH+ is an example of reduced in metabolism.
Explanation:
Oxidation and reduction or redox reaction means transfer of electron from one atom to another in a compound.
In photosynthesis and respiration redox reaction are seen.
The substance that gain the electrons in metabolic reaction is said to be reduced.
In respiration process oxygen is being reduced. The NAD+ accepts hydrogen ion and 2 e- to become NADH+H+. These are electron carriers.
The reactions can be seen in glycolysis, Kreb's cycle.
The worm feeds via a "pumping" action in which it first uptakes the fluid surrounding it. Then, it expels the fluid while trapping any bacteria within it. The bacteria are then digested for energy and nutrients.
