The following are the environmental factors that can damage genes that code for these enzymes. radiation from sun, various chemicals and x-rays. these agents are referred to as environmental mutagens. they result to changes in the genetic make up of the organism and in turn affect the production of enzymes. enzymes are protein in nature and once the DNA has been compromised their production is affected. in most cases mutated DNA produces enzymes with lost or abnormal function.
The answer would be 4 out of 10 which is 40 percent
The processes and their reactions are discussed below.
<h3><u>
Explanation</u>:</h3>
<u>Carbon dioxide</u>:
In case of plants the carbon dioxide is needed to produce glucose in the process of photosynthesis. This step is very crucial for the survival of each and every organisms in the living world. The energy for this process of photosynthesis is found from sun's rays.
In case of humans, carbon dioxide is produced through respiration. This produces energy that helps the organism to sustain living.
Oxygen:
It is produced by plants from photosynthesis through splitting of water. The energy for this process comes from Sun's energy.
In case of animals, the oxygen is needed for respiration. This is required to accept the electron in the last step of aerobic respiration. This produces the energy that helps to sustain the living.
Water:
Both plants and animals require the water for performing their metabolic works. The water is obtained by plants from soil through roots and conducted to leaves by vascular tissues xylem. Similarly the animals obtain water from drinking. They need the water to perform digestion, and each and every metabolic process.
Glucose:
Glucose is produced by plants from photosynthesis. It is produced absorbing the energy of Sun's rays.
In case of animals, the animals obtain glucose from food and they digest the glucose through respiration and produce energy that helps them to sustain life.
