An enzyme-catalyzed reaction was run at five different temperatures (trials 1-5). The results are shown in the data table above. Based on the data, what is the optimal
temperature at which this enzyme functions? (2 points)
O 20°C
O 40°C
O 60°C
O 70°C

Maybe 40°C

Explanation:

because at higher temperatures the enzymes get denatured lost their shapes so maybe its 40°C

i hope it's right if not so advance sorry :)

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
