<span>These organisms obtain energy and carbon from the physical environment and use it to produce their food. They make sugars and other compounds using sunlight as a source of energy and carbon dioxide as a carbon source. The evolutionary advantages for these organisms are the periodic renewal of atmospheric O2 for all living beings. The production of organic matter and food webs of any ecosystem. Without them, there is an extinction of all living organisms due to the non-renewal of atmospheric O2 and the excessive accumulation of CO2 in the atmosphere.</span>
The answer is 25%. The
other 75% will have dominant phenotype. However,
in the dominant phenotype, 25% have a homozygous dominant genotype, while the remaining
50% have a heterozygous genotype. Find attached a punnet square that will
clearly illustrate this;
An amylase is an enzyme that catalyses the hydrolysis of starch into a sugar.

The correct answer is - A and D.
Explanation:
Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.
