Answer: Geologic time is divided into units. Major changes in the earth's surface or climate and the extinction of species help to divide the time scale into smaller units.
Explanation: Rocks grouped within each unit contain a similar fossil record.
Asexual reproduction produces genetically identical offspring and sexual reproduction creates variation in the offspring. When the environment changes and it affects the asexual offspring it will affect all identical copies whereas since the sexual offspring have more variation, they are more likely to survive.
Answer:
Animals perform cellular respiration.
Explanation:
As plants release Oxygen through the process of photosynthesis, animals use this oxygen (as well as other inputs) to perform cellular respiration which releases Carbon Dioxide. Cellular respiration helps animals get the energy from sugar converted into more simple molecules such as ATP (Adenine Triphosphate).
