Q: What is the chemical formula for a glucose molecule? Read this paragraph and choose the correct option from the provided answers: The sugar glucose is a covalent compound. When sugar dissolves in water, it forms individual glucose molecules (C 6 H 12 O 6 ). You can see how this happens in the Figure below . Sugar is polar like water, so sugar molecules also have positive and negative ends. Forces of attraction between oppositely charged ends of water and sugar molecules pull individual sugar molecules away from the sugar crystal. Little by little, the sugar molecules are separated from the crystal and surrounded by water. You can watch this happening in the video at the following URL: http://www. youtube. com/watch?v=hydUVGUbyvU. Choices: - a5 h12 o6 - H2 C3 NA6 - d5 h12 o6 - c6 h12 o6 A:
c6 h12 o6

Q: Where does the earth gets its energy from? Read this paragraph and choose the correct option from the provided answers: Earth gets its energy from the Sun. The Sun gives off photons of energy that travel in waves. All the wavelengths of the Sun's energy make up the electromagnetic (EM) spectrum. Choices: - decomposers - precipitation - heat - sun A:
(Answer)
sun

Ques: Q: Compared to thoracic and lumbar types, the cervical type of what structures carry the least amount of body weight? Read this paragraph and choose the correct option from the provided answers: Cervical Vertebrae Typical cervical vertebrae, such as C4 or C5, have several characteristic features that differentiate them from thoracic or lumbar vertebrae (Figure 7.25). Cervical vertebrae have a small body, reflecting the fact that they carry the least amount of body weight. Cervical vertebrae usually have a bifid (Y-shaped) spinous process. The spinous processes of the C3C6 vertebrae are short, but the spine of C7 is much longer. You can find these vertebrae by running your finger down the midline of the posterior neck until you encounter the prominent C7 spine located at the base of the neck. The transverse processes of the cervical vertebrae are sharply curved (U-shaped) to allow for passage of the cervical spinal nerves. Each transverse process also has an opening called the transverse foramen. An important artery that supplies the brain ascends up the neck by passing through these openings. The superior and inferior articular processes of the cervical vertebrae are flattened and largely face upward or downward, respectively. The first and second cervical vertebrae are further modified, giving each a distinctive appearance. The first cervical (C1) vertebra is also called the atlas, because this is the vertebra that supports the skull on top of the vertebral column (in Greek mythology, Atlas was the god who supported the heavens on his shoulders). The C1 vertebra does not have a body or spinous process. Instead, it is ring-shaped, consisting of an anterior arch and a posterior arch. The transverse processes of the atlas are longer and extend more laterally than do the transverse processes of any other cervical vertebrae. The superior articular processes face upward and are deeply curved for articulation with the occipital condyles on the base of the skull. The inferior articular processes are flat and face downward to join with the superior articular processes of the C2 vertebra. The second cervical (C2) vertebra is called the axis, because it serves as the axis for rotation when turning the head... Choices: - nasal - nuclei - ametic - vertebrae A:
Ans: vertebrae

Q: What occurs when a cold air mass runs into a warm air mass? Read this paragraph and choose the correct option from the provided answers: A cold front occurs when a cold air mass runs into a warm air mass. This is shown in Figure below . The cold air mass moves faster than the warm air mass and lifts the warm air mass out of its way. As the warm air rises, its water vapor condenses. Clouds form, and precipitation falls. If the warm air is very humid, precipitation can be heavy. Temperature and pressure differences between the two air masses cause winds. Winds may be very strong along a cold front. Choices: - an occluded front - a stationary front - a snow day - a cold front A:
(A).
a cold front

Ques:Q: What types of living things are divided into nonvascular and vascular groupings? Read this paragraph and choose the correct option from the provided answers: The most basic division of modern plants is between nonvascular and vascular plants. Vascular plants are further divided into those that reproduce without seeds and those that reproduce with seeds. Seed plants, in turn, are divided into those that produce naked seeds in cones and those that produce seeds in the ovaries of flowers. Choices: - organs - mammals - animals - plants A:

Ans:plants

Ans:
receptors
