Answer 1

As i am unable to read the first question cause its blur..not clear so sorry for that.

Answer no.2 - Option no. (B)

Rheumatoid arthritis is a joint disorder that involves inflammation and weakening of the lining of different body joints.The affected joints may lose their shape that leads to loss of normal mobility.

Answer no. 3- Option (b)

Solution B has a higher hydrogen ion concentration than solution A.

Answer 4- Option no (c)

URACIL is present in RNA, But not present in DNA.RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine.

Answer 5-Option ( a)

Troponin has a calcium binding site. Some of the calcium attach to troponin causing to change shape.

Answer 6- Option (d)

Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell.

Answer 7-Option (c)

Fatty acid B is saturated
