Phenotype, physical appearance, is determined by the genotype, an organism's genetic makeup.
Answer:
D. a wide variety of gradual and sudden changes to ecosystems
Explanation:
There have been different global climatic changes throughout the history of planet earth. The changes have been gradual or abrupt and have been due to various causes, such as those related to changes in orbital parameters, precession , variations in solar radiation, continental drift, periods of intense volcanism, meteorite impacts etc. Some changes to the ecosystems related to climatic changes are, for example,The Cretaceous-Tertiary extinction (which probably caused the extinction of the dinosaurs), the contraction of the forests during the last glacial maximum promoting biological diversification, the melting of the polar caps increasing sea level etc.
The physical change is when water slowly disappears when the sun shines upon it. Its weight and volume decreases.
The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically, nothing has changed. The plant still looks the same. However, changes occur internally; these internal changes are chemical in nature.
