The answer would be D.
Enzymes activity increases as the temperature increase so, therefore the answer would be D.
but to be fair they all would work.
They think that people started as a fish and there was a resolution into a bigger fish then into a land creature then into a monkey then into a man. They think that the earth was a little rock at the beginning but then other rocks joined it and it became 1 big planet. But this is just what they think.
A 15-month-old child, equivalent to a child of 1 year and 3 months of age, should have began weaning from bottle feeding from 6 months of age. Tooth decay or dental caries are commonly associated with prolonged bottle feeding as the sugars and other substances in milk; when drank from a teat from a bottle; prolongs the exposure of teeth to the milk, leading to overgrowth of bacteria causing dental caries.
1. The answer is "<span>the energy required to start the reaction".
</span>This energy is called as activation energy of the reaction. If the activation
energy is high, reaction is slow. Enzymes help to carry out the reaction by
a new path by reducing the activation energy. But the energy of reactants
and the products remain as same as without enzyme.
2. The answer is "reaction in cells would be too slow to sustain life<span>".
</span>If the activation energy is very high for the reaction, then that reaction will
be very slow and will require more time<span> to complete the reaction. Then survival is
very low. Hence, the roll of enzymes is very important to sustain life.</span>
