Valve between the left ventricle and Aorta?

Correct Answer: a power structure in which each member knows his or her own place

Explanation:

Hierarchy is a system of ranking in which members of a particular society are ranked in an ascending order depending on various factors.

 

Hence, the term hierarchy refers to a power structure in which each member knows his or her own place.

Correct Answer: Near distance

Explanation:

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.

Correct Answer: Glucose

Explanation:

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

Correct Answer: Hydrophobic

Explanation:

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.

Correct Answer: Helioseismology

Explanation:

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.

Correct Answer: a surface exposed by a retreating glacier

Correct Answer: All the above

Explanation:

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.

Correct Answer: Inactive people use more energy so they should consume fewer calories.

Explanation:

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

Correct Answer: dry climates

Explanation:

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.

Correct Answer: Joules

Explanation:

Energy is measured in units called Joules.

 

Joule is unit of work or energy in the International System of Units (SI) which is equal to the work done by a force of one newton acting through one metre.

 

1 Joule  =  10⁷ ergs or 0.7377 foot-pounds.
