What is the chemical reaction that takes place when a microorganism turns one substance into another?
fermentation: Any of many anaerobic biochemical reactions in which an enzyme (or several enzymes produced by a microorganism) catalyses the conversion of one substance into another; especially the conversion (using yeast) of sugars to alcohol or acetic acid with the evolution of carbon dioxide.
What is the ancient false idea that life appeared from nowhere?
Spontaneous generation is a body of thought on the ordinary formation of living organisms without descent from similar organisms. The theory of spontaneous generation held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.
What is the gooey liquid in plant and animal cells?

Which of these grows on dead animals?
DECOMPOSERS. Many of the millions of organisms that live in the soil, including bacteria, fungi, insects, and earthworms, are known as decomposers. They live on the remains of dead plants and animals and break down these organic remains into simple chemicals that are released into the soil.
Do producers give off or take in carbon dioxide?
During photosynthesis, plants and other producers transfer carbon dioxide and water into complex carbohydrates, such as glucose, under the influence of sunlight. Animals are called consumers, because they use the oxygen that is produced by plants.
What causes carbon dioxide to decrease in the air?
Not only does the burning of forests release carbon dioxide, but deforestation can also affects the level of carbon dioxide. Trees reduce the amount of carbon dioxide from the atmosphere during the process of photosynthesis, so fewer trees means more carbon dioxide left in the atmosphere.
What feature do plant cells have but not animal cells?
The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
Which part of an onion root cell gives it a brick like structure?
Cell Walls Give Structure In onion cells the tiles look very similar to rectangular bricks laid in offset runs. The rigid walls combined with water pressure within a cell provide strength and rigidity, giving plants the necessary structure to resist gravity and pressure.
