Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
Answer:
Heterotroph. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

Answer:
The half of the Moon that points toward the Sun looks bright because it is lit by sunlight. The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. ... As it moves around Earth, more and more of the lit side comes into view.
Scientists use fossils to learn about organisms' lives and evolutionary relationships, to understand geological change, and even to locate fossil fuel reserves.
