mitosis

(Question)
Q: For most waves, energy is proportional to what, a term that describes the height of the wave? Read this paragraph and choose the correct option from the provided answers: Light also behaves like a package of energy. It turns out that for light, the energy of the "package" of energy is proportional to its frequency. (For most waves, energy is proportional to wave amplitude, or the height of the wave. ) The mathematical equation that relates the energy (E) of light to its frequency is. Choices: - wave frequency - wave volume - wave threshold - wave amplitude A:
(Answer)
wave amplitude

Ques: Q: Free-flowing electrons enable what materials to conduct electricity and heat very well? Read this paragraph and choose the correct option from the provided answers: This model for metallic bonding explains some of the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end, allowing an electrical current to pass through the material with minimal resistance. Additionally, because the electron "glue" that holds the metal atoms together is very easy to deform and reshape, bulk metals can be easily hammered, bent, and pulled without breaking apart. Choices: - noble gases - alloys - acids - metals A:
Ans: metals

(Q).
Q: Green cyanobacteria on a lake produce food through what process? Read this paragraph and choose the correct option from the provided answers: Green cyanobacteria on a lake make food by photosynthesis. Choices: - spermatogenesis - glycolysis - reverse transferase - photosynthesis A:
(A).
photosynthesis

Ques:Q: Unlike free-living species of flatworms that are predators or scavengers, what forms feed from the tissues of their hosts? Read this paragraph and choose the correct option from the provided answers: Flatworms The relationships among flatworms, or phylum Platyhelminthes, is being revised and the description here will follow the traditional groupings. Most flatworms are parasitic, including important parasites of humans. Flatworms have three embryonic germ layers that give rise to surfaces covering tissues, internal tissues, and the lining of the digestive system. The epidermal tissue is a single layer of cells or a layer of fused cells covering a layer of circular muscle above a layer of longitudinal muscle. The mesodermal tissues include support cells and secretory cells that secrete mucus and other materials to the surface. The flatworms are acoelomate, so their bodies contain no cavities or spaces between the outer surface and the inner digestive tract. Physiological Processes of Flatworms Free-living species of flatworms are predators or scavengers, whereas parasitic forms feed from the tissues of their hosts. Most flatworms have an incomplete digestive system with an opening, the "mouth," that is also used to expel digestive. Choices: - aquatic - mutualistic - herbiverous - parasitic A:

Ans:parasitic

Ques:Q: Most vascular plants are seed plants, also known as? Read this paragraph and choose the correct option from the provided answers: Most vascular plants are seed plants, or spermatophytes. They reproduce with seeds and pollen. Some modern seed plants are gymnosperms that produce seeds in cones. Choices: - sporozoans - bacteria - fungus - spermatophytes A:

Ans:
spermatophytes
