Ans.
White blood cells or WBCs are immune blood cells, responsible for protecting the body against cancer cells, foreign invaders and infectious diseases. These cells include monocytes, lymphocytes, and natural killer cells.
If an individual is able to fight with infectious agents and can protect the body from diseases, it indicates that the WBCs of his body are functioning properly. Individuals with a normal functioning immune cells are called as immunocompetents.

Answer:
An autoimmune disease is the result of the immune system attacking its own healthy cells and tissues. An example of this disease is rheumatoid arthritis, which attacks the joints; hence, becoming them to be inflamed.
Explanation:
To counteract this effect, painkillers, steroids, and anti-inflammatory drugs are taken to reduce this inflammation and pain in the joints. Physical therapies and surgeries are also performed to treat this disease.
Answer;
-Ossification (growth) centers
Explanation;
-Ossification is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues.
-Primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone. The secondary ossification centers appear, during the first years of postnatal life, in the epiphyses of the bone (at the ends of the bone).
Answer:
Thioredoxin
Explanation:
Ribonucleotides serve as precursors for synthesis of deoxyribonucleotides and the reaction is catalyzed by enzyme ribonucleotide reductase. The reduction of a ribonucleotide into deoxyribonucleotide requires a pair of hydrogen atoms.
These hydrogen atoms are supplied from NADPH via ubiquitous protein thioredoxin. The oxidized form of thioredoxin is reduced back in a reaction catalyzed by thioredoxin reductase.
