How long does it take photosynthesis to occur?

Photosynthesis occurs in two stages. In the first phase, light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of carbohydrates.

The process only takes a couple seconds to take place but both of the stages require the molecules to have a certain energy level.

When the air temperature is low, fewer molecules have the proper energy level and so only a small amount of photosynthesis takes place. Warm temperatures allow a lot more molecular conversions.

In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle

Neporo4naja [7]

Answer:

Explanation:

Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation

p² + 2pq + q²

where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,

F of homozygous ( featherless legs) = q²

F of heterogyous ( carrier of featherless allele) = 2pq

F (q²) = 128/200 = 0.64

q = √0.64 = 0.8

and p + q = 1

p = 1 - 0.8 = 0.2

2pq = 2 × 0.2 × 0.8 = 0.32

number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
