In meiosis the crossing over the chromosomes takes place which brings the transfer of character and further increase the variation
They lower the activation energy. The energy needed for a reaction to occur.

BTW. The enzyme is a ferment conducting chemical reactions in living organisms. Each enzyme catalyzes a chemical reaction strictly defined for a specific substrate and conditions.
I think it's pretty interesting to look at it from the universe perspective: we are part of the universe, so that means the universe evolved consciousness, and/or the universe is conscious of itself, in a way. We seem to be a flabbergasting, rare outcome of evolution and favorable environmental conditions. For now our purpose should be self-preservation and continued inquiry into this astounding set of circumstances.
Answer:
(4) use a larger number of snails
Explanation:
The size of sample selected from a population of interest during a research has effect on the accuracy/validity of the outcome of such research. The effect of sample size can be deduced from the formula for determining sample size to be selected during a research which is expressed below:

Where <em>Z-score = confidence level</em>
<em> SD = Pre-determined standard deviation</em>
<em> ME = Margin of error.</em>
<em>The margin of error is inversely proportional to the sample size. Hence, the higher the sample size, the lower the error margin and vice versa.</em>
<em>The student could have increased the validity of the outcome of his research by using a larger number of snail samples in each of the tanks.</em>
The correct option is option 4.
Answer:
