Correct answer: A). Chemical
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane, chlorophyll absorbs the energy from the sunlight. After that, the light energy is converted into chemical energy by using water. Then the lower energy NADP+ get high energy electrons and protons and get converted into NADPH and ATP.
Answer:
The question is incomplete, the missing part i.e. the environmental change is:
(A) biomagnification
(B) acid rain
(C) eutrophication
The answers are:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels
Explanation:
1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.
2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.
3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.
<h2>Answer:</h2>
<u>Human stomach cannot digest fatty acids while ruminant stomach can digest them.</u>
<h2>Explanation:</h2>
There are certain fatty acids which can be absorbed directly through ruminal wall into blood stream which usually fulfills 60 to 80 % of energy needs of Ruminants. On the other hand human stomach can not break down cellulose and derive no energy from it. So we can say that Ruminants stomach can digest fatty acids while human stomach cannot break down these cellulose.
Answer:
B. genotype
Explanation:
Genotype determines an organism's phenotype.
