Natural selection act directly upon <u>Alleles</u>
Explanation:
Genes, such as that of fur color, have many variants called alleles. Natural selection act on the alleles and chooses the best fit for an environment and eliminates the disadvantageous ones from the population over generations. Mutations are a rare occurrence that increases the number of allelic variants of a genes on which natural selection can act upon.
Discontinuous variation is when a trait is seen in a population in two or more different forms and there is no continuation along a gradient. A good example that Mendel studied is flower color. The flowers were either white or purple. There was no in between color. This is caused by an allele for purple or a lack of an allele for purple, which produces no pigment, or white.
In photosynthesis, carbon dioxide is reduced. This reduction occurs during the Calvin cycle. The energy for the reduction is gained from Light reaction.
<u>Explanation:</u>
The pigment called Chloroplasts that are present in plants helps them in the conversion of light energy into chemical energy. This pigment contains electrons has higher energy that will be transported in the photosynthesis p[process.
The main source of this process to take place is energy that is obtained from sun. Chlorphylls abosrb the solar energy.The electrons in the chloroplast produces NADPH and ATP. This process is called as the light reactions as the main source of this reaction is light.
No because if we we're burning calories it would mean that we were physically burning
