Answer the following question given this paragraph: The Figure above shows how the electromagnetic spectrum displays a wide variation in wavelength and frequency. Radio waves have wavelengths of as long as hundreds of meters, while the wavelength of gamma rays are on the order of 10 -12 m. The corresponding frequencies range from 10 6 to 10 21 Hz. Visible light can be split into colors with the use of a prism ( Figure below ), yielding the visible spectrum of light. Red light has the longest wavelength and lowest frequency, while violet light has the shortest wavelength and highest frequency. Visible light wavelength ranges from about 400 700 nm with frequencies in the range of 10 14 Hz. Q: Visible light can be split into colors with the use of a what? Choices: - spectrum - convex lenses - kaleidoscope - prism A:
prism

(Answer)
nervous
Ques: Answer the following question given this paragraph: Figure 5.2 Layers of Skin The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. Beneath the dermis lies the hypodermis, which is composed mainly of loose connective and fatty tissues. Q: The epidermis is made of which closely packed cells? Choices: - cancer cells - nerve cells - muscle cells - epithelial cells A:
Ans: epithelial cells
(Q).
Answer the following question given this paragraph: Agents of Decomposition The fungus-like protist saprobes are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes. For instance, many types of oomycetes grow on dead animals or algae. Saprobic protists have the essential function of returning inorganic nutrients to the soil and water. This process allows for new plant growth, which in turn generates sustenance for other organisms along the food chain. Indeed, without saprobe species, such as protists, fungi, and bacteria, life would cease to exist as all organic carbon became "tied up" in dead organisms. Q: Fungus-like protist saprobes play what role in a food chain and are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes? Choices: - aphids - Soil - fluxes - decomposers A:
(A).
decomposers
Ques:Answer the following question given this paragraph: To begin mitosis, the DNA in the nucleus wraps around proteins to form chromosomes . Each organism has a unique number of chromosomes. In human cells, our DNA is divided up into 23 pairs of chromosomes. Replicated DNA forms a chromosome made from two identical sister chromatids , forming an "X" shaped molecule ( Figure below ). The two chromatids are held together on the chromosome by the centromere . The centromere is also where spindle fiber microtubules attach during mitosis. The spindles separate sister chromatids from each other. Q: What forms when the dna in the nucleus wraps around proteins? Choices: - rna - genes - ribosomes - chromosomes A:

Ans:chromosomes
Question: Answer the following question given this paragraph: Electromagnetic waves that are commonly called light fall roughly in the middle of the electromagnetic spectrum.

Choices: - complementary, incandescent, fluorescent - diffuse, ambient, opaque - solar , visible , ultraviolet - infrared, visible, ultraviolet A:
Answer:
infrared, visible, ultraviolet
