Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.
Answer:
Viruses, fungi, bacteria, protozoans, and worms.
Explanation:
They all are pathogens which can cause infection.
Answer:
Gives us energy by providing energy to the cells inside our body. Carbohydrates in food are used first. When they are all used up, the body then uses fats, and then proteins as energy sources.
The answer is B, can be destroyed by variations in the temperature.
Answer A is not correct because enzymes are made from protein, not fatty acids.
Answer C is not correct because enzymes are reusable, as their shape of the active site is not hanged by the reaction, thus having the ability to bind into other substrates again and again.
D is not correct because enzymes actually provide a pathway to start a reaction with a lower activation energy, therefore, it does not raise the amount of activation energy.
Answer B is correct because enzymes can be affected by temperature and pH, each type of enzyme only work the fastest at a specific temperature and pH, once the temperature is too high or he pH is too extreme, the active site of the enzyme is altered and thus cannot bind into substrates again. We can them denatured.
<u>Answer</u>: Option 3 Coevolution
<u>Explanation</u>:
<em>Coevolution</em> is a process in which two individuals reciprocally affect each other's evolution. In this process the interacting species exert selective pressures on each other thus, affecting their evolution. Due to this reciprocal adaption they become so close that the evolution of one species is affected by the other.
