Answer the following question given this paragraph: When you are cold, what does your body do to keep warm? You shiver to warm up your body. When you are too warm, you sweat to release heat. When any living organism gets thrown off balance, its body or cells help it return to normal. In other words, living organisms have the ability to keep a stable internal environment. Maintaining a balance inside the body or cells of organisms is known as homeostasis . Like us, many animals have evolved behaviors that control their internal temperature. A lizard may stretch out on a sunny rock to increase its internal temperature, and a bird may fluff its feathers to stay warm ( Figure below ). Q: Maintaining a balance inside the body or cells of organisms is known as? Choices: - ketosis - equanimity - consciousness - homeostasis A:
homeostasis
Answer the following question given this paragraph: Sexual reproduction is typically slower. However, it also has an advantage. Sexual reproduction results in offspring that are all genetically different. This can be a big plus for a species. The variation may help it adapt to changes in the environment. Q: What kind of reproduction results in offspring that are generally all genetically different? Choices: - perceptual - asexual - individual - sexual A:
sexual
Q: Answer the following question given this paragraph: Regular physical exercise is important in preventing lifestyle diseases such as cardiovascular disease, some types of cancer, type 2 diabetes, and obesity. Regular exercise also improves the health of the muscular system. Muscles that are exercised are bigger and stronger than muscles that are not exercised. Q: Cardiovascular disease, some types of cancer, type 2 diabetes, and obesity are considered what kind of preventable diseases? Choices: - environmental diseases - atmosphere diseases - age diseases - lifestyle diseases A:
A: lifestyle diseases
Question: Answer the following question given this paragraph: Cumulus clouds are white and puffy. Convection currents make them grow upward and they may grow very tall. When they produce rain, they are called cumulonimbus. Q: What causes cumulus clouds to grow upward? Choices: - moisture currents - gas currents - mantle currents - convection currents A:
Answer: convection currents

Answer the following question given this paragraph: Summary The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces. Mostcovalent compounds consist of molecules, groups of atoms in which one or more pairs of electrons are shared by at least two atoms to form a covalent bond. The atoms in molecules are held together by the electrostatic attractionbetween the positively charged nuclei of the bonded atoms and the negatively charged electrons shared by the nuclei. The molecular formula of a covalent compound gives the types and numbers of atoms present. Compounds that contain predominantly carbon and hydrogen are called organic compounds, whereas compounds that consist primarily of elements other than carbon and hydrogen areinorganic compounds. Diatomic molecules contain two atoms, andpolyatomic molecules contain more than two. A structural formula indicates the composition and approximate structure and shape of a molecule. Single bonds, double bonds, and triple bonds are covalent bonds in which one, two, and three pairs of electrons, respectively, are shared between two Saylor URL: http://www. saylor. org/books. Q: What kind of compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero? Choices: - neutral compounds - zero charged compunds - zeronic ions - ionic compounds A:
