Q: Answer the following question given this paragraph: Controlling muscles and maintaining balance are just two of the roles of the nervous system. The nervous system also lets you:. Q: Controlling muscles and maintaining balance are just two of the roles of what system? A:
Answer: nervous system

Problem:OPTIONS:
- physical transport
- wave diffusion
- active transport
- passive transport

Answer the following question given this paragraph: Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. Concentration refers to the number of particles of a substance per unit of volume. The more particles of a substance in a given volume, the higher the concentration. A substance always moves from an area where it is more concentrated to an area where it is less concentrated. It's a little like a ball rolling down a hill. It goes by itself without any input of extra energy. Q: What type of transport occurs when substances cross the plasma membrane without any input of energy from the cell? A:
****
A: passive transport

Answer the following question given this paragraph: 2.2 | Chemical Bonds By the end of this section, you will be able to: Explain the relationship between molecules and compounds Distinguish between ions, cations, and anions Identify the key difference between ionic and covalent bonds Distinguish between nonpolar and polar covalent bonds Explain how water molecules link via hydrogen bonds Atoms separated by a great distance cannot link; rather, they must come close enough for the electrons in their valence shells to interact. But do atoms ever actually touch one another? Most physicists would say no, because the negatively charged electrons in their valence shells repel one another. No force within the human bodyor anywhere in the natural worldis strong enough to overcome this electrical repulsion. So when you read about atoms linking together or colliding, bear in mind that the atoms are not merging in a physical sense. Instead, atoms link by forming a chemical bond. A bond is a weak or strong electrical attraction that holds atoms in the same vicinity. The new grouping is typically more stableless likely to react againthan its component atoms were when they were separate. A more or less stable grouping of two or more atoms held together by chemical bonds is called a molecule. The bonded atoms may be of the same element, as in the case of H2, which is called molecular hydrogen or hydrogen gas. When a molecule is made up of two or more atoms of different elements, it is called a chemical compound. Thus, a unit of water, or H2O, is a compound, as is a single molecule of the gas methane, or CH4. Three types of chemical bonds are important in human physiology, because they hold together substances that are used by the body for critical aspects of homeostasis, signaling, and energy production, to name just a few important processes. These are ionic bonds, covalent bonds, and hydrogen bonds. Q: Ionic, covalent, and hydrogen are three important types of what type of interaction between different types of atoms? A:
OPTIONS:
- forms
- conflicts
- levels
- bonds

Answer the following question given this paragraph: Forms of radiation that cause cancer include ultraviolet (UV) radiation and radon ( Figure below ). UV radiation is part of sunlight. It is the leading cause of skin cancer. Radon is a natural radioactive gas that seeps into buildings from the ground. It can cause lung cancer. Q: What is the leading cause of skin cancer? A:
OPTIONS:
- artificial light
- dehydration
- smoking
- sunlight

Answer: sunlight

input with options: Answer the following question given this paragraph: The concentration of hydronium ions in a solution is known as acidity. In pure water, the concentration of hydronium ions is very low; only about 1 in 10 million water molecules naturally breaks down to form a hydronium ion. As a result, pure water is essentially neutral. Acidity is measured on a scale called pH , as shown in Figure below . Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Q: What is the scale on which acidity is measured? A:
OPTIONS:
- m
- hp
- g
- ph
output:
ph
