Water in plants is the first donor in photosynthesis. They help the plants to grow and obtain the nutrients that they need, such as oxygen. The water is considered to be the ultimate electron donor in the photosynthesis because without the water, the plant will not sustain life.

When the acetyl-CoA produced during -oxidation in the liver exceeds the capacity of the citric acid cycle, the excess acetyl-Co
Oliga [24]

Answer:

There is a need to transform the accumulation of acetyl-CoA into the ketone bodies, as one knows that acetyl-CoA is both labile and possess an enormous amount of energy. Hence, acetyl-CoA due to its unstable characteristic is not ideal for circulation within the tissues, and at the same time, the compound acetyl-CoA does not possess the tendency to pass through the cell membrane.  

Due to these reasons, the conversion of acetyl-CoA into the ketone bodies is done, the ketone bodies also act as an alternative source of energy. The ketone bodies work as water-soluble correspondents of fatty acids. The production of ketone bodies generally takes place within the liver cells' mitochondrial matrix. The three forms of ketone bodies are beta-hydroxybutyrate, acetoacetate, and acetone.  

The production of ketone bodies by the liver cells helps the cells of the brain at the time of starvation, as the brain cannot use fatty acids as an energy source, as the fatty acids cannot pass through the blood-brain barrier.

In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle
Neporo4naja [7]

Answer:

64

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

What is the result of the greenhouse effect?
Annette [7]
Greenhouse gases, such as carbon dioxide (CO2), trap heat from the Sun. This causes the Earth's climate to grow warmer, resulting in "global warming".
