Answer the following question given this paragraph: Covalent compounds form individual molecules rather than crystals. Compared with ionic compounds, they have low melting and boiling points. They are also poor conductors of electricity. In polar covalent compounds, oppositely charged ends of different molecules attract each other. This affects the properties of polar compounds. Q: Covalent compounds form individual molecules rather than what? Choices: - carbon - chemicals - atoms - crystals A:
crystals

Answer the following question given this paragraph: Monocots Plants in the monocot group are primarily identified as such by the presence of a single cotyledon in the seedling. Other anatomical features shared by monocots include veins that run parallel to the length of the leaves, and flower parts that are arranged in a three- or six-fold symmetry. True woody tissue is rarely found in monocots. In palm trees, vascular and parenchyma tissues produced by the primary and secondary thickening meristems form the trunk. The pollen from the first angiosperms was monosulcate, containing a single furrow or pore through the outer layer. This feature is still seen in the modern monocots. Vascular tissue of the stem is not arranged in any particular pattern. The root system is mostly adventitious and unusually positioned, with no major tap root. The monocots include familiar plants such as the true lilies (which are at the origin of their alternate name of Liliopsida), orchids, grasses, and palms. Many important crops are monocots, such as rice and other cereals, corn, sugar cane, and tropical fruits like bananas and pineapples (Figure 26.17). Q: What is the type of plant that has a single cotelydon in the seedling? Choices: - dicot - conifer - moss - monocot A:
(Answer)
monocot
Ques: Answer the following question given this paragraph: Neural Control of Thermoregulation The nervous system is important to thermoregulation, as illustrated in Figure 33.22. The processes of homeostasis and temperature control are centered in the hypothalamus of the advanced animal brain. Q: The processes of homeostasis and temperature control are centered in the hypothalamus of the advanced animal brain, thus thermoregulation depends on what organ system? Choices: - circulatory system - digestive system - cardiovascular system - nervous system A:
Ans: nervous system
(Q).
Answer the following question given this paragraph: A related process to diffusion is the effusion. Effusion is the process of a confined gas escaping through a tiny hole in its container. Effusion can be observed by the fact that a helium-filled balloon will stop floating and sink to the floor after a day or so. This is because the helium gas effuses through tiny pores in the balloon. Both diffusion and effusion are related to the speed at which various gas molecules move. Gases that have a lower molar mass effuse and diffuse at a faster rate than gases that have a higher molar mass. Q: Both diffusion and effusion are related to the speed at which what objects move? Choices: - electricity - copper molecules - solids - gas molecules A:
(A).
gas molecules
Ques:Answer the following question given this paragraph: Work is directly related to both the force applied to an object and the distance the object moves. It can be represented by the equation: Work = Force Distance. Q: Force times distance is the equation for what? Choices: - power - speed - gravity - work A:

Ans:work

Ans:
crustaceans
