Rzqust [24]

Answer:

There is no short answer.

Explanation:

The chlorophyll is the pigment that gives the plants' leaves their green colors and it is also responsible for the photosynthesis process which takes place in the mitochondria. In the fall as the leaves change color, the amount of chlorophyll decreases and this impacts the mitochondria as it also decreases the amount of work the mitochondria does.

Artist 52 [7]

Answer:

Dominance

Explanation:

Mendel discovered certain principles that governs heredity or inheritance when he conducted experiments. In his experiments, he discovered that an organism receives two copies of a gene called allele, from each parent.

He discovered that one allele of a gene has the ability to mask or suppress the expression of its allele variant in the same gene. He called the allele that masks or is expressed, DOMINANT allele, while the allele that is masked, RECESSIVE allele. Based on this observation, he named his first principle, LAW OF DOMINANCE.

In this case, he crossed a purebreeding round-seeded pea plant and a purebreeding wrinkled-seeded pea plant, he noticed that in the F1 generation, all the offsprings possessed round seeds. This led to the conclusion that the allele for round seeds masks the phenotypic expression of the wrinkled allele in a heterozygous state. Hence, the allele for round seeds is dominant while the allele for Wrinkled seeds is recessive.
