Answer:
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes.
Explanation:
<span>B. have amniotic eggs.</span> Frogs and toads don't have amniotic eggs. Frogs and toads lay "frog's spawn" these are clumps of eggs covered with jelly like substance. Frog's spawn may contain thousands of eggs.
The equation is glucose + oxygen carbon dioxide + water and energy is produced in the form of ATP.
Explanation:
Cellular respiration is a metabolic process in which glucose combines with oxygen to produce carbon dioxide and water with energy stored as ATP.
Glucose + Oxygen gas → Carbon dioxide + Water + energy in ATP
ATP is Adenosine TriPhosphate.
In the body, during cellular respiration, oxygen gas is inhaled and carried to sites in the body where food in form of glucose obtained from plant is broken down.
When food is broken down aerobically i.e in the presence of oxygen gas, carbon dioxide and water is produced and energy is stored in form of ATP.
