Answer:
1/8 (12.5 %)
Explanation:
Cross: IAi X IAIB
F1: 1/4 IAIA 1/4 IAIB 1/4 IAi 1/4 IBi
Phenotypes:
- IAIA and IAi >> type A blood
- IBi >> type B blood
- IAIB >> type AB blood
Phenotypic frequency type A blood: 1/2 (i.e., 1/4 IAIA + 1/4 IAi) >>
Probability to have 3 offspring with type A blood: 1/2 x 1/2 x 1/2 = 1/8
The human ABO blood group is a system consisting of there different alleles: A, B, and O. This system is used in genetics as an example of codominance because both A and B alleles are expressed in heterozygous individuals (i.e., IAIB), whereas only the allele A is expressed in individuals that have A and O alleles (since O allele is recessive to the A and B alleles).
Answer:B.
It was used to prove that smoking causes health problems.
Explanation:
Answer:
The correct answer is plants use photosynthesis to make their own food.
Explanation:
photosynthesis is one of the most important physiological process that occur in plants.
photosynthesis use the light energy from sun and then convert the light energy to chemical energy.
The chemical energy is then used used to make glucose various by various enzymatic process.
Answer:
Diffusion
Explanation:
Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.
The phase after ovulation (release of an egg) is called luteal phase. The stimulating follicle hormone (fsh) and luteinizing hormone (lh) are produced in the pituitary.
The FSH promotes the growth of an egg in the follicle while the LH facilitates its release from the follicle. Once the egg is released, the two hormones decrease, resulting in the rise of estrogen and progesterone.
