Answer the following question given this paragraph: Temperature increases with altitude in the thermosphere. Surprisingly, it may be higher than 1000 C (1800 F) near the top of this layer! The Sun's energy there is very strong. The molecules absorb the Sun's energy and are heated up. But there are so few gas molecules that the air still feels very cold. Molecules in the thermosphere gain or lose electrons. They then become charged particles called ions. Q: As altitude rises, what happens to the temperature in the thermosphere? Choices: - oxygen increases - oxygen decreases - temperature decreases - temperature increases A:
temperature increases
Answer the following question given this paragraph: Density is an important physical property of matter. It reflects how closely packed the particles of matter are. Q: What physical property of matter reflects how closely packed the particles of matter are? Choices: - makeup - build up - mass - density A:
density
Q: Answer the following question given this paragraph: Atoms have a mass that is based largely on the number of protons and neutrons in their nucleus. Q: The mass of atoms is based on the number of protons and neutrons in what? Choices: - electrons - molecules - components - nucleus A:
A: nucleus
Question: Answer the following question given this paragraph: Sensory organs such as the eyes contain cells called sensory receptors that respond to particular sensory stimuli. Q: Sensory organs that respond to particular sensory stimuli contain cells called what? Choices: - artificial receptors - stimulus receptor - whole receptors - sensory receptors A:
Answer: sensory receptors

Answer the following question given this paragraph: Subphylum Chelicerata includes animals such as spiders, scorpions, horseshoe crabs, and sea spiders. This subphylum is [4] predominantly terrestrial, although some marine species also exist. An estimated 103,000 described species are included in subphylum Chelicerata. The body of chelicerates may be divided into two parts and a distinct "head" is not always discernible. The phylum derives its name from the first pair of appendages: the chelicerae (Figure 15.23a), which are specialized mouthparts. The chelicerae are mostly used for feeding, but in spiders, they are typically modified to inject venom into their prey (Figure 15.23b). As in other members of Arthropoda, chelicerates also utilize an open circulatory system, with a tube-like heart that pumps blood into the large hemocoel that bathes the internal organs. Aquatic chelicerates utilize gill respiration, whereas terrestrial species use either tracheae or book lungs for gaseous exchange. Q: Chelicerata are know for their first pair of appendages, also know as what? Choices: - ambers - chelicides - maxillae - chelicerae A:
**Answer**
chelicerae

Answer the following question given this paragraph: Another exception to Mendel's laws is a phenomenon called codominance . For example, our blood type shows codominance. Do you know what your blood type is? Are you A? O? AB? Those letters actually represent alleles. Unlike other traits, your blood type has three alleles, instead of two!. Q: What do the letters in our blood types represent? Choices: - genomes - proteins - iron levels - alleles A:
(Answer)
alleles
