Cellular respiration is important as it allows plants and animals to break down sugar and into usable energy, usually in the form of ATP. Organism can not use sugar as energy, so without the process of cellular respiration, the cell would not have energy. ATP is important product of cellular respiration because organism can utilize ATP as energy and thus able to work. Cellular respiration starts in the cytoplasm with glycolysis. Then, all of the other steps such as The Krebs Cycle and Oxidation phosphorylation takes place in the mitochondria.

Hope this help. Sorry if it has bad grammar

erastova [34]

Complete question:

Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited.

A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child will also have the disease? Express your answer as a fraction using the slash symbol and no spaces (for example, 1/2).

Answer:

The probability that the second child will also have the disease is 1/16.

Explanation:

Available data:

Two genes independently inherited: one for blood type, the other for disease
Man with type A blood x Woman with type B blood
Both parents are heterozygous for the gene that causes the disease; Dd

If the man has A blood, and the woman has B blood, and they already have an affected child, this means that they must be heterozygous for blood type too.

Three linked autosomal loci were studied in cucumbers: fruit color (dark vs. light), tendril size (long vs. reduced) and fruitin

Zina [86]

Answer:

Explanation:

1. Progeny observed in the experiment is calculated by adding all the progeny numbers observed in the :

TIME TO FRUIT TENDRIL SIZE FRUIT COLOR NUMBER

Normal normal dark 370

normal normal light 32

early normal light 971

early normal dark 28

early reduced dark 25

early reduced light 483

normal reduced light 36

normal reduced dark 810

TOTAL

PROGENCY 2755

2. The locus in the center is TIME TO FRUIT. Tendril size is at the beginning of the locus and the distance between the locus B and locus C is R2
