Well there are three reasons
it drains into rivers, streams, etc. or
it seeps into soil and gather underground as ground-water
or
falls into high mountains and freeze and in the summer it will melt and flows into the rivers
Alleles in the F1 must be Tt to have height variety in the F2.
Because the red eyes are recessive to black eyes, the parents could be heterozygous. Recessive alleles only show if two recessive alleles are combined. Thus the offsprings phenotypes of the gene would be C. Rr and rr
Food molecules contain chemical energy which is released when its chemical bonds are broken.
Food undergoes digestion in the digestive system and is broken down into its monomer units. Carbohydrates, which are the principal source of energy, are broken down into glucose. Glucose is the monomer unit of carbohydrates.
Glucose then is taken up by cells and is used in cellular respiration, which involves three main stages namely glycolysis, Krebs cycle and the electron transport chain, through which a glucose molecule is processed to form at least 36 molecules of ATP.
ATP is the form of energy that cells use.
I dont know if you mean it like this but
metamorphic rocks are located deep underground but often found on surface of earth due to uplift
