The law of conservation of matter states that matter cannot be created or destroyed. The law of conservation of energy states that energy cannot be created or destroyed. Both of the laws state that both cannot be created or destroyed, but both take on different forms, or become different kinds of matter or energy.
Answer:
Option-D
Explanation:
Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.
In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.
In the given question, the graph shows:
1. The absorption of oxygen till 6 am which is required during cellular respiration.
2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.
3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.
Thus, Option-D is correct.
The discovery of the Rhesus factor affected society by improving the success rate of blood transfusions. Prior to the Rhesus system being implemented, blood was typed according to the ABO system alone. This meant a significant number of blood transfusions failed due to immunogenic reactions to the rhesus factor leading to agglutination of blood. It also helped prenatal care as people became aware of the possibility of the mother and child being Rhesus incompatible. This condition could be combated by an injection of antibodies.
