Answer the following question given this paragraph: The Moon has no atmosphere. With no atmosphere, the Moon is not protected from extreme temperatures. The average surface temperature during the day is approximately 107C (225F). Daytime temperatures can reach as high as 123C (253F). At night, the average temperature drops to -153C (-243F). The lowest temperatures measured are as low as -233C (-397F). Q: What does the moon not have to protect it from extreme temperatures? Choices: - oceans - metals - oxygen - atmosphere A:
atmosphere

Answer the following question given this paragraph: Mixtures have different properties depending on the size of their particles. Three types of mixtures based on particle size are solutions, suspensions, and colloids, all of which are described in Table below . You can watch videos about the three types of mixtures at these URLs:. Q: What are the three types of mixtures? Choices: - absorbing , suspensions , colloids - Powders, Gels, Smooth - cosmic , suspensions , colloids - solutions, suspensions, colloids A:
(Answer)
solutions, suspensions, colloids
Ques: Answer the following question given this paragraph: Anatomy of the Eye The photoreceptive cells of the eye, where transduction of light to nervous impulses occurs, are located in the retina (shown in Figure 36.17) on the inner surface of the back of the eye. But light does not impinge on the retina unaltered. It passes through other layers that process it so that it can be interpreted by the retina (Figure 36.17b). The cornea, the front transparent layer of the eye, and the crystalline lens, a transparent convex structure behind the cornea, both refract (bend) light to focus the image on the retina. The iris, which is conspicuous as the colored part of the eye, is a circular muscular ring lying between the lens and cornea that regulates the amount of light entering the eye. In conditions of high ambient light, the iris contracts, reducing the size of the pupil at its center. In conditions of low light, the iris relaxes and the pupil enlarges. Q: The photoreceptive cells of the eye, where transduction of light to nervous impulses occurs, are located in this? Choices: - pupil - cornea - sclera - retina A:
Ans: retina
(Q).
Answer the following question given this paragraph: A: Most ocean waves are caused by wind blowing across the water. Moving air molecules transfer some of their energy to molecules of ocean water. The energy travels across the surface of the water in waves. The stronger the winds are blowing, the larger the waves are and the more energy they have. Q: Most ocean waves are caused by what? Choices: - radiation - animals - gravity - wind A:
(A).
wind
Ques:Answer the following question given this paragraph: A biofilm is a thin layer of bacteria that sticks to a surface. Cells in a biofilm are all alike, but they may play different roles, such as taking in nutrients or making the "glue" that sticks the biofilm to the surface. The sticky plaque that forms on teeth is a biofilm of bacterial cells. Q: What is a thin layer of bacteria that sticks to a surface? Choices: - a choanocyte - a spicule - a monofilm - a biolfilm A:

Ans:a biolfilm
Question: Answer the following question given this paragraph: Leaves may vary in size, shape, and their arrangement on stems. Nonflowering vascular plants have three basic types of leaves: microphylls ("tiny leaves"), fronds, and needles. Figure below describes each type. Q: Nonflowering vascular plants have three basic types of leaves: microphylls, fronds, and what other type? Choices: - molds - tubes - stems - needles A:
Answer:
needles
