Answer the following question given this paragraph: Many animals, especially mammals, use metabolic waste heat as a heat source. When muscles are contracted, most of the energy from the ATP used in muscle actions is wasted energy that translates into heat. Severe cold elicits a shivering reflex that generates heat for the body. Many species also have a type of adipose tissue called brown fat that specializes in generating heat. Q: Shivering and adipose tissue called brown fat are used by mammals in particular to produce what? Choices: - energy - blood - nutrition - heat A:
heat

Answer the following question given this paragraph: Habitats Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. Several protist species are parasites that infect animals or plants. A few protist species live on dead organisms or their wastes, and contribute to their decay. Q: Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. several protist species are parasites that infect animals or plants. a few protist species live on dead organisms or their wastes, and contribute to what? Choices: - greenhouse gas - habitat loss - spontaneous mutation - their decay A:
their decay

Answer the following question given this paragraph: Q: Which system carries out long-distance transport of materials between the root and shoot systems? Choices: - circulatory tissue system - reproductive tissue system - perceptual tissue system - vascular tissue system A:
vascular tissue system

Answer the following question given this paragraph: This tissue includes several types of specialized cells. Pavement cells, large, irregularly shaped parenchymal cells which lack chloroplasts, make up the majority of the epidermis. Within the epidermis, thousands of pairs of bean-shaped schlerenchymal guard cells swell and shrink by osmosis to open and close stomata , tiny pores which control the exchange of oxygen and carbon dioxide gases and the release of water vapor. The lower surfaces of some leaves contain as many as 100,000 stomata per square centimeter. Q: Pavement cells, large, irregularly shaped parenchymal cells which lack chloroplasts, make up the majority of what? Choices: - dermis - layers - Skin - epidermis A:
epidermis
