Which statement about anaerobic respiration is true? Anaerobic respiration prevents muscle fatigue. Anaerobic respiration generates a high yield of ATP. Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese. Anaerobic respiration can provide energy to animals for several days in the absence of oxygen.

Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.

Which statement about the cell membrane is true? It contains cellulose and sugars that are involved in communication. It is present in animal cells only. It is rigid and elastic for supporting the cell's shape. It prevents harmful substances from entering a cell.

It prevents harmful substances from entering a cell.

What role does cellular respiration play in the water cycle? It removes H2O from the atmosphere during glycolysis. It removes H2O from the atmosphere during acetyl CoA formation. It releases H2O to the atmosphere during the citric acid cycle. It releases H2O to the atmosphere during electron transport.

It releases H2O to the atmosphere during electron transport.

Living things only come from other living things.

How were Redi's and Pasteur's experiments different? Redi studied broth, but Pasteur tested meat. Pasteur studied flies, but Redi tested meat. Pasteur tested for microorganisms, but Redi studied larger organisms. Redi tested for microorganisms, but Pasteur studied larger organisms.

Pasteur tested for microorganisms, but Redi studied larger organisms.

Which statement about vacuoles is true? Only plant cells contain vacuoles. Only animal cells contain vacuoles. Vacuoles are larger in plant cells than in animal cells. Vacuoles are larger in animal cells than in plant cells.

Vacuoles are larger in plant cells than in animal cells.

When a scientist is conducting research about all the plants and wildlife in the Mojave Desert as well as the desert's resources, such as water and soil, the scientist is studying a community. a population. a species. an ecosystem.

an ecosystem.

Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. What would most likely happen to the legume population if Rhizobia suddenly became extinct? become extinct learn to fix nitrogen benefit in the long run stay the same

become extinct
