C) matter is changed into various forms but the total quantity remains unchanged.
Answer:
B. rr
Explanation:
Genotype- Is the genetic makeup of an organism.
An homozygous individual is one who has similar allele e.g AA
It could either be in dominant form(AA) or recessive form(aa)
An heterozygote individual has two different allele in its genotype e.g Aa
A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.
The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.
The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.

See the answer below
Explanation:
First, let us look at the complete equation of respiration:
![C_6H_1_2O_6 + 6O_2 -->6CO_2 + 6H_2O](https://tex.z-dn.net/?f=C_6H_1_2O_6%20%2B%206O_2%20--%3E6CO_2%20%2B%206H_2O)
The respective number of each atom in the reactants and the products can be filled in the table thus:
Types of atom Number of atom in reactants Number of atom in products
Carbon 6 6
Hydrogen 12 12
Oxygen 18 18
<em>The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction. </em>
