Explain why photosynthesis and cellular respiration are considered to be paired processes​

Biology
1 answer:
denis23 [38]3 years ago
4 0

Because they are the same chemical reaction but reversed. Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).

(I don't remember this clearly so it may be wrong, i'll look into it and come back!)

In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-
Alex_Xolod [135]

Answer:

1128.

Explanation:

The dominant taster phenotype is 1482.

The recessive taster phenotype = 2400 – 1482 = 918 .

Recessive phenotypes = 2400 – 1482 = 918

The recessive phenotype frequency = q² = 918 / 2400 = 0.38.

the recessive allele frequency q = √0.38 = 0.62.

The dominant allele frequency, p = 1-q = 1- 0.62 = 0.38

The heterozygous frequency =  2pq = 2 ×0.38 × 0.62 = 0.47 .

The heterozygous individual in the population = 0.47 × 2400 = 1128.

Thus, the answer is 1128.
