Answer: Polygenic inheritance
Explanation:
Polygenic inheritance is a phenomenon that explains how a character like skin color show a range of more or less continuous variation due to many genes controlling it. And this is unlike Mendel traits that are controlled by single genes.
So, skin color in an individual is expressed as red hair and pale skin.
Answer:
True
Explanation:
Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular substrate, for enzyme-substrate complex and later enzyme product complex to formed.
They act by lowering the activation energy in the organic chemical reaction therefore increase the rate at which chemical reactions progress.
Hence when the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.
Answer:
In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.
Explanation:
The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.
In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.
