Answer: Bull's genotype: RW
Cow's genotype: WW
50% are roan color
50% are white color
Explanation:
A cross between a heterozygous roan bull (RW) and a homozygous white cow (WW), will yield 50% roan and 50% white offsprings.

Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.
The answer is RESPIRATION
Answer: Enzyme has an active site in a particular unique shape which a substrate recognises and bind to.
Explanation: For a reaction to occur, all enzymes have an active site that a specific substrate will bind to forming an enzyme-substrate complex, then a required product is created. Due to this, sometimes a reaction may not occur because of inhibition. Enzyme inhibition is caused by having a molecule with a conformation that resembles a subtrate, the molecule or substance will compete with the substrate for the enzyme active site preventing a reaction to take place. Inhibition may either be competitive as described above or non-competitive where a substance will not directly bind to the active site but will change the conformation of the enzyme in a way that a subtrate will not be able to bind.
