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: a surface exposed by a retreating glacier
Correct Answer: Aortic valve
Explanation:
The Aortic valve - located between the left ventricle and the aorta
The Mitral valve - located between the left atrium and left ventricle
The Tricuspid valve - located between the right atrium and the right ventricle (and)
The Pulmonary (pulmonic) valve - located between the right ventricle and the pulmonary artery.
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: 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.
Correct Answer: FALSE
Explanation:
Natural resources are resources taken from nature to satisfy our needs. As wild animals are on the earth naturally, they are considered as natural resources.
Hence, the given statement is false.
Correct Answer: All the above
Explanation:
Viruses are responsible for some of the most dangerous and deadly diseases including influenza, ebola, rabies and smallpox.
Despite their potential to kill, these potent pathogens are in fact considered to be non-living.
Reasons:
1. Viruses don't have any cells, like living organisms do. They have protein coats but no organelles or other cellular machinery. Just a little DNA packet.
2. Viruses can't produce new proteins, DNA, or RNA and therefore are unable to reproduce on their own. They need infected cells' machinery to make all of these and produce new virons.
3. Viruses have no metabolic activity. They don't use or convert energy and have no ongoing interior processes. They're basically just inert structures until they impact a potential host cell.
Correct Answer: Retinol
Explanation:
Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids.
