Mitosis is cell division through body cells, meiosis is the division of sex cells
Answer:
The only one I know is yellow seeds
Explanation:
Answer: one offspring out of the four will have a recessive-recessive genotype.
Explanation: A cross between two parents who are heterozygous for a gene that has a simple dominant-recessive pattern of inheritance will produce four offsprings: one will be homozygous dominant, two will be heterozygous dominant while one will be homozygous recessive.
Homozygous dominant offspring has two dominant alleles, heterozygous dominant offspring has one dominant allele and one recessive allele while a homozygous recessive offspring has two recessive alleles.
For example, a cross between two parents that are heterozygous (Tt) for tall will produce one TT, two Tt and one tt. TT is homozygous dominant, Tt is heterozygous dominant and tt is homozygous recessive. An offspring with genotype tt has a two recessive alleles thus have a recessive-recessive genotype. Therefore the number of offsprings with recessive-recessive genotype is one.

Answer:
B) Regurgitation
Explanation:
Regurgitation refers to the backward flow of blood due to any reasons. Presence of atrioventricular valves between atrium and ventricle prevents the regurgitation, that is backward flow of blood. Structural or functional damage of any atrioventricular valves does not allow them to prevent the regurgitation.
Example: Valvular insufficiency is the condition wherein the cusps of the valves (mostly the mitral valve) become stiff and leads to backward flow of blood.
