Answer:
C
Explanation:
Trees take up carbon dioxide from the atmosphere and reduce to make carbohydrates. This is powered by the energy of the sun that is taped by chlorophyll pigments during photosynthesis. The energy is used to split water molecules into H+ and O2-. Then the following chemical reaction ensues;
6CO2 + 6H2O ------> C6H12O6 + 6O2
Answer:
an enzyme produced chiefly by certain bacteria, having the property of cleaving DNA molecules at or near a specific sequence of bases.
For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
