Question 7

Study of the sun is called

Accepted Answer

Helioseismology is the study of the solar interior using observations of waves on the Sun's surface. It has done much to improve our understanding of the interior of the Sun, testing the physical inputs used to model stellar interiors and providing a detailed map of the Sun's structure and internal rotation.

Question 8

Lipids are insoluble in water because lipids are

Accepted Answer

Lipids are soluble in solvents of low polarity, which simply means that lipids are soluble in nonpolar solvents. This solubility property is a result of the large nonpolar regions that are indicative of the lipid molecule.

Question 9

Which of the following is not a polymer?

Accepted Answer

Since A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Glucose is not a polymer.

Question 10

Planets do not twinkle because

Accepted Answer

Stars twinkle because they’re so far away from Earth that when light from the stars passes through the atmosphere, it is bent countless times due to refraction, making it look like as if they were blinking. The sun and other planets doesn’t twinkle because it’s too close to Earth compared to other stars.

Accepted Answer

Common properties of Minerals are : 1. All minerals are formed in a natural process. 2. Minerals are inorganic 3. Minerals are crystalline solids. 4. Every mineral is an element or compound with a definite chemical composition.

Question 14

Accepted Answer

The given statement option A) is False regarding energy balance. It should be "Inactive people use less energy so they should consume fewer calories."

Question 15

Which of the following causes tornadoes?

Accepted Answer

Conditions suitable for the formation of a tornado develop when varying temperatures and humidity come together and form thunderclouds. This refers to the presence of warm and moist condition in the lower atmosphere and cold and dry conditions in the upper atmosphere. The place where these varying masses of air meet is known as the dry-line. Such conditions, which are suitable for the formation of a tornado, are most often observed just before a low pressure system develops. Once the ideal conditions occur, the warm air tries to rise in the atmosphere, while the cold air blocks it. This makes the air in between rotate horizontally. In the meanwhile, the land is heated by the Sun, and hence, the air near the ground becomes warm and starts rising. Continuous fueling by the heat energy from the Sun ensures that the warm air has an upper hand over cold air. As a result of this, the cold air at the top starts sinking and the warm air below starts rising in a spinning motion. As the amount of warm air increases, the formation gains height and becomes intense. The intensity of these devastating tornadoes is such that they can clear off anything that comes in their path.
