Answer:
Large change in temperature makes heat flow fast.
Explanation:
Answer:
a) False
b) False
c) True
Explanation:
a) Most sulfur oxides formed during combustion come from sulfur in the air: The sulfur burns in presence of oxygen to produce sulfur oxides, the source of sulfur is anthropogenic activities (Human activities).
So the given statement is false.
b) A flue gas scrubber removes SO2 pollution in a coal-fired power plant by using lime to convert the SO2 into alcohols:
False
The lime reacts with sulfur dioxide to give carbon dioxide and calcium sulfite.
c) True
c)
Answer:
d. Transketolase
Explanation:
Transketolase utilize thiamine diphosphate (ThDP) as cofactor has reduced activity during the thiamine deficiency and results in the tissue damage. <u>The levels of steady-state mRNA of transketolase in human lymphoblasts, fibroblasts and neuroblastoma cells are found to be lower in the thiamine-deficient cultures. </u>
Thus, deficiency in TPP directly decrease the activity of enzyme, transketolase.
Answer:
1.3-bromo,2-chloro,4-floro hexane
3.bromocyclo pentane
Answer:
1.61 × 10⁶ kJ
Explanation:
The human burns energy so as to be healthy.
The amount of energy burnt per day by an adult human is 2 × 20³ kcal per day. Since there is 24 hours in a day, the amount of energy burnt per hour is 2 × 20³ × 24 = 48 × 20³ kcal per hour.
The conversion rate of kcal to kJ is 1 kcal = 4.184 kJ. Therefore converting the kcal per hour to kJ per hour gives:
48 × 20³ × 4.184 = 200.882 × 20³ kJ = 1.61 × 10⁶ kJ
