Please help me!
A reducing atmosphere is conducive to the synthesis of molecules because
a. it contains oxygen, an element found in many molecules.
b. it tends to grab electrons, breaking chemical bonds.
c. it contains nitrogen, an element found in many molecules.
d. it tends to donate electrons, forming chemical bonds.
The activity of human enzymes peaks at about 37°C. How would the activity of a human enzyme be different at 44°C?
a. It would work faster.
b. It would work slower.
c. It would be unaffected.
d. It would not function.
Gene expression can be controlled at all of the following protein synthesis stages EXCEPT
a. initiation of translation.
b. RNA processing.
c. DNA unpacking.
d. protein degradation.
e. protein folding.
In a population, 84 out of 100 individuals display the dominant phenotype. Use the Hardy–Weinberg equation to predict the frequency of heterozygotes.
a. 16 out of 100
b. 24 out of 100
c. 27 out of 100
d. 48 out of 100
I look them up on the net and couldn't find a thing.
