Answer:
the ducks have associated people with food handouts and so they become close.
Explanation:
Answer:
If the products contain 3 nitrogen atoms, then so did the reactants since overall mass is conserved in a chemical reaction.
Explanation:
Answer:
D. Increase in temperature from 20 degrees C to 37 degree C
Explanation:
A decrease in substrate concentration might not necessarily lead to an increase in enzymatic activities.
Enzymes are pH specific. Thus increasing the pH of operation from 6.8 to 7.4 might destroy the enzyme.
Reactants need to overcome a minimum energy (activation energy) before they can be converted to products. The higher this energy, the lower the rate of reaction. Hence, increasing in activation energy will lead to a lower rate of enzymatic reaction.
<em>Enzymes work optimally at a temperature that is close to the human's body temperature which is 37.5 degrees. Hence, increasing temperature from 20 degrees to 37 degrees will result in an increased enzymatic activities.</em>
The correct option is D.
Answer:
B. Straight away from the source
Explanation:
In an isotropic medium, light always travels in a straight line away from the source.
