Answer the following question given this paragraph: Like the formation of ions, the formation of charged matter in general depends on the transfer of electrons either between two materials or within a material. Three ways this can occur are friction, conduction, and polarization. In all cases, the total charge remains the same. Electrons move, but they aren't destroyed. This is the law of conservation of charge . Q: Electrons move, but they aren't destroyed. this is the law of conservation of what? Choices: - energy - cost - matter - charge A:
charge
Answer the following question given this paragraph: Q: Ciliary muscles control the shape of the lens, which bends light and focuses it on what? Choices: - the pupil - the vitreous fluid - the cornea - the retina A:
the retina
Q: Answer the following question given this paragraph: During this ester bond formation, three water molecules are released. The three fatty acids in the triacylglycerol may be similar or dissimilar. Fats are also called triacylglycerols or triglycerides because of their chemical structure. Some fatty acids have common names that specify their origin. For example, palmitic acid, a saturated fatty acid, is derived from the palm tree. Arachidic acid is derived from Arachis hypogea, the scientific name for groundnuts or peanuts. Fatty acids may be saturated or unsaturated. In a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are saturated with hydrogen; in other words, the number of hydrogen atoms attached to the carbon skeleton is maximized. Stearic acid is an example of a saturated fatty acid (Figure 3.14). Q: Fats are also called triacylglycerols or triglycerides because of their what? Choices: - atomic number - chemical weight - elemental type - chemical structure A:
A: chemical structure
Question: Answer the following question given this paragraph: Each Volvox , shown in Figure above , is a colonial organism. It is made up of between 1,000 to 3,000 photosynthetic algae that are grouped together into a hollow sphere. The sphere has a distinct front and back end. The cells have eyespots, which are more developed in the cells near the front. This enables the colony to swim towards light. Q: What do the cells in the front of a volvox typically develop to help swim towards light? Choices: - tumors - sunspots - vertebrates - eyespots A:
Answer: eyespots

Answer the following question given this paragraph: When a new air mass moves over a region it brings its characteristics to the region. This may change the area's temperature and humidity. Moving air masses cause the weather to change when they contact different conditions. For example, a warm air mass moving over cold ground may cause an inversion. Q: An inversion may result when what kind of mass moves over cold ground? Choices: - warm water - cold water - cold air - warm air A:
**Answer**
warm air
(Q).
Answer the following question given this paragraph: During asexual reproduction, fungi produce haploid spores by mitosis of a haploid parent cell. A haploid cell has just one of each pair of chromosomes. The haploid spores are genetically identical to the parent cell. Spores may be spread by moving water, wind, or other organisms. Wherever the spores land, they will develop into new hyphae only when conditions are suitable for growth. Q: During asexual reproduction, fungi produce haploid spores by what process involving a haploid parent cell? Choices: - osmosis - evaporation - divergence - mitosis A:
(A).
mitosis
