The results of the di-hybrid cross of pea plants with round and yellow seeds was the evidence that Mendel fond that supported his law of independent assortment.
<u>Explanation:</u>
Law of independent assortment states that the alleles of two different genes are inherited independent of each other. The law of independent assortment was formulated by Gregor Mendel . Cross of a pea plant with yellow and round seeds with a pea plant having green and wrinkled seeds gave evidence of the law of independent assortment.
When it comes to seed color yellow color is dominant to green. When it comes to seed shape round seed is dominant to wrinkled seed. Let the letter R represent round seed and R represent wrinkled seed. The letter Y represent yellow seed and letter y represent green seed.
The genotype of pea plant with round and yellow seed is RRYY and the genotype of round and wrinkled is rryy. The cross between round yellow and wrinkled green can be represented as follows
Gametes RY ry
F1 generation RrYy RrYy RrYy RrYy
All the plants of the F1 generation have round and yellow seeds.
The F1 generation plants are then bred together
RRYY RrYY RRYy RrYy RrYY rrYY RrYy rrYy RRYy RrYy RRyy Rryy RYy rrYy Rryy rryy
r
Are the progenies with phenotypes like round yellow, round green, wrinkled yellow and wrinkled green.
The combination of the characters of roundness and color is observed in the F2 generation proves that the characters of round and yellow as well as wrinkled and green doesn’t appear strictly in combination. This means that they are independently assorted which proves the law of independent assortment.
Answer:
Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.

Explanation:
Cellular respiration is the chemical process that makes energy required for day-to-day metabolic functions of an organism. The resulting energy is in the form of a molecule called ATP (adenosine triphosphate). There are two types of cellular respiration: aerobic and anaerobic, but both types start with glycolysis. Glycolysis is the breakdown of glucose molecules which makes some ATP.
Aerobic respiration uses oxygen. It occurs in the mitochondria of cells. The overall chemical formula for this is
C6H12O6 + 6CO2 ---> 6CO2 + 6H20 + 38ATP
In this process, there are multiple stages: glycolysis, Krebs Cycle, and Electron Transport Chain (ETC). All of these stages are used to make ATP, but ETC makes the greatest amount of ATP. The other stages create reactants needed for ETC.
Anaerboic respiration does not use oxygen and is also called fermentation. It occurs after glycolysis. There are two types of this: lactic acid fermenation,which occurs in muscle cells and produces lactic acid, and alcoholic fermentation, which occurs in yeasts and can make bread and alcohol. The process produces some molecules that can produce more ATP in glycolysis.
