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.
E.the number of amino acids in the protein
Answer:
A) genetic influences and chemical imbalances in the brain
Explanation:
An anxiety disorder is a psychiatric disorder where the individual experiences an excessive and irrational worry in everyday situations. Generalized anxiety disorder, phobias, panic attacks, etc are examples of anxiety disorders.
<em>Anxiety does not have a specific cause, it can be the result of different factors like changes in the brain's chemistry, environmental stress or even genetics.</em>

If the The speed of light is approximately 3 × 108 meters per second (m/sec) so the speed of light written in standard numerical form is 300,000,000 m/sec. You will just simply move the place holders to 8 places to the right since the exponent is a positive number. So 3^8= 3x100000000 which is equal to 300,000,000 .
Answer:
96000YEARS
Explanation:
Given that 1/28 = 8 half lives
this means that 8 half lives ,
and the given fossil should have 1/28 of the isotope
8 half lives = 1200 x 8
= 96000years
therefore the predicted Neandertal fossils is 96000years
