Answer the following question given this paragraph: Almost all protozoa can move. They have special appendages for this purpose. You can see different types in Figure below . Cilia (cilium, singular) are short, hair-like projections. Pseudopods are temporary extensions of the cytoplasm. Flagella are long, whip-like structures. Flagella are also found in most prokaryotes. Q: Pseudopods are temporary extensions of what? Choices: - the cell wall - the mucus - cytopods - the cytoplasm A:
the cytoplasm
Answer the following question given this paragraph: Q: Young eutherians complete their embryonic development within what? Choices: - pollen grains - ovaries - spores - uterus A:
uterus
Q: Answer the following question given this paragraph: Solutions We have previously defined solutions as homogeneous mixtures, meaning that the composition of the mixture (and therefore its properties) is uniform throughout its entire volume. Solutions occur frequently in nature and have also been implemented in many forms of manmade technology. We will explore a more thorough treatment of solution properties in the chapter on solutions and colloids, but here we will introduce some of the basic properties of solutions. The relative amount of a given solution component is known as its concentration. Often, though not always, a solution contains one component with a concentration that is significantly greater than that of all other components. This component is called the solvent and may be viewed as the medium in which the other components are dispersed, or dissolved. Solutions in which water is the solvent are, of course, very common on our planet. A solution in which water is the solvent is called an aqueous solution. A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration). Concentrations may be quantitatively assessed using a wide variety of measurement units, each convenient for particular applications. Molarity (M) is a useful concentration unit for many applications in chemistry. Molarity is defined as the number of moles of solute in exactly 1 liter (1 L) of the solution: M = mol solute L solution. Q: What term is used to describe a solution in which water is the solvent? Choices: - liquids solution - hydro solution - sediment solution - aqueous solution A:
A: aqueous solution
Question: Answer the following question given this paragraph: The planets make slightly elliptical orbits around the Sun. Q: What is the shape of the orbits that planets make around the sun? Choices: - conical - variable - elongated - elliptical A:
Answer: elliptical

Answer the following question given this paragraph: Radioactivity is the ability of an atom to emit, or give off, charged particles and energy from the nucleus. The charged particles and energy are called by the general term radiation . Only unstable nuclei emit radiation. When they do, they gain or lose protons. Then the atoms become different elements. (Be careful not to confuse this radiation with electromagnetic radiation, which has to do with the light given off by atoms as they absorb and then emit energy. ). Q: What is the ability of an atom to emit, or give off, charged particles and energy from the nucleus? Choices: - magnetism - electrolysis - electromagnetism - radioactivity A:
**Answer**
radioactivity
Q: Answer the following question given this paragraph: 5. Thermal energy is the energy of moving atoms of matter. All matter has thermal energy because atoms of all matter are constantly moving. An object with more mass has greater thermal energy than an object with less mass because it has more atoms. Q: An object with more mass has greater thermal energy than an object with less mass because it has more what? Choices: - molecules - ions - gravity - atoms A:
A: atoms
