Answer the following question given this paragraph: Endotherms and Ectotherms Animals can be divided into two groups: some maintain a constant body temperature in the face of differing environmental temperatures, while others have a body temperature that is the same as their environment and thus varies with the environment. Animals that do not control their body temperature are ectotherms. This group has been called cold-blooded, but the term may not apply to an animal in the desert with a very warm body temperature. In contrast to ectotherms, which rely on external temperatures to set their body temperatures, poikilotherms are animals with constantly varying internal temperatures. An animal that maintains a constant body temperature in the face of environmental changes is called a homeotherm. Endotherms are animals that rely on internal sources for body temperature but which can exhibit extremes in temperature. These animals are able to maintain a level of activity at cooler temperature, which an ectotherm cannot due to differing enzyme levels of activity. Q: Animals that are endotherms or ectotherms are distinguished by the ability to maintain a constant what? Choices: - step temperature - bearing temperature - Moving Tempature - body temperature A:
body temperature
Q: Answer the following question given this paragraph: The red blood cells of a person with sickle-cell anemia (left) are long and pointed, rather than straight, like normal cells (right). The abnormal cells cannot carry oxygen properly and can get stuck in capillaries. Q: The abnormal cells cannot carry oxygen properly and can get stuck where? Choices: - muscles - Viens - Arteries - capillaries A:
A: capillaries

Answer the following question given this paragraph: All living thingseven the simplest life formshave a complex chemistry. Living things consist of large, complex molecules, and they also undergo many complicated chemical changes to stay alive. Thousands (or more) of these chemical reactions occur in each cell at any given moment. Metabolism is the accumulated total of all the biochemical reactions occurring in a cell or organism. Complex chemistry is needed to carry out all the functions of life. Q: What is the accumulated total of all the biochemical reactions occurring in a cell or organism called? Choices: - respiration - expansion - circulation - metabolism A:
**Answer**
metabolism

Answer the following question given this paragraph: Exocytosis is the type of vesicle transport that moves a substance out of the cell. A vesicle containing the substance moves through the cytoplasm to the cell membrane. Then, the vesicle membrane fuses with the cell membrane, and the substance is released outside the cell. You can watch an animation of exocytosis at the link below. Q: The type of vesicle transport that moves a substance out of the cell is called? Choices: - morphogenesis - metabolism - endocytosis - exocytosis A:
(A).
exocytosis
