Answer the following question given this paragraph: The small intestine is a narrow tube that starts at the stomach and ends at the large intestine. In adults, it's about 7 meters (23 feet) long. Most chemical digestion and almost all nutrient absorption take place in the small intestine. Q: What is the name of the narrow tube that begins at the stomach and ends at the large intestine? Choices: - small stomach - pancreas - small tissues - small intestine A:
small intestine

Answer the following question given this paragraph: There is an associated magnetic field ( B ) which propagates outward as well (see Figure 24.6). The electric and magnetic fields are closely related and propagate as an electromagnetic wave. This is what happens in broadcast antennae such as those in radio and TV stations. Closer examination of the one complete cycle shown in Figure 24.5 reveals the periodic nature of the generator-driven charges oscillating up and down in the antenna and the electric field produced. At time t = 0 , there is the maximum separation of charge, with negative charges at the top and positive charges at the bottom, producing the maximum magnitude of the electric field (or E -field) in the upward direction. One-fourth of a cycle later, there is no charge separation and the field next to the antenna is zero, while the maximum. Q: The electric and magnetic fields are closely related and propagate as what? Choices: - mechanical wave - thermal energy - sound wave - electromagnetic wave A:
(Answer)
electromagnetic wave
Ques: Answer the following question given this paragraph: Leaves are the keys not only to plant life but to virtually all life on land. The primary role of leaves is to collect sunlight and make food by photosynthesis. Leaves vary in size, shape, and how they are arranged on stems. You can see examples of different types of leaves in Figure below . Q: Which is the process through which leaves collect sunlight and make food? Choices: - Greenhouse - compress - richness - photosynthesis A:
Ans: photosynthesis
(Q).
Answer the following question given this paragraph: Using Lewis Dot Symbols to Describe Covalent Bonding The valence electron configurations of the constituent atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. For example, chlorine, with seven valence electrons, is one electron short of an octet. If two chlorine atoms share their unpaired electrons by making a covalent bond and forming Cl2, they can each complete their valence shell:. Q: If two chlorine atoms share their unpaired electrons by making a covalent bond and forming cl2, they can each complete their what? Choices: - hypothesized shell - radiative shell - electron shell - valence shell A:
(A).
valence shell
Ques:Answer the following question given this paragraph: Upon compiling his results for many thousands of plants, Mendel concluded that the characteristics could be divided into expressed and latent traits. He called these, respectively, dominant and recessive traits. Dominant traits are those that are inherited unchanged in a hybridization. Recessive traits become latent, or disappear, in the offspring of a hybridization. The recessive trait does, however, reappear in the progeny of the hybrid offspring. An example of a dominant trait is the violet-flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait. The fact that the recessive trait reappeared in the F2 generation meant that the traits remained separate (not blended) in the plants of the F1 generation. Mendel also proposed that plants possessed two copies of the trait for the flower-color characteristic, and that each parent transmitted one of its two copies to its offspring, where they came together. Moreover, the physical observation of a dominant trait could mean that the genetic composition of the organism included two dominant versions of the characteristic or that it included one dominant and one recessive version. Conversely, the observation of a recessive trait meant that the organism lacked any dominant versions of this characteristic. Q: What happens to the recessive traits in the offspring of a hybridization? Choices: - they dominate - remain recessive - they replicate - they disappear A:

Ans:they disappear
Ques:Answer the following question given this paragraph: Both of these people are participating in a board sport, but the man on the left is snowboarding in Norway while the woman on the right is sandboarding in Dubai. Snow and sand are both kinds of matter, but they have different properties. What are some ways snow and sand differ? One difference is the temperature at which they melt. Snow melts at 0C, whereas sand melts at about 1600C! The temperature at which something melts is its melting point. Melting point is just one of many physical properties of matter. Q: The temperature at which something melts is refered to as what? Choices: - precipitation point - evaporation point - boiling point - melting point A:

Ans:
melting point
