A Cyclone is a large scale air mass that rotates around strong centers of low pressure.

• Water vapors are formed when water is heated.
• This heat is released to atmosphere when water vapors convert to water during rains.
• The heat released, warms the air around and makes it to move up. This also results in decreased air pressure.
• Hence, cooler air from surrounding rushes to take the warm air’s place.
• This repeats till a low pressure system with surrounding high speed winds is created. This is called a Cyclone.
• Cyclone depends on wind speed, direction, temperature and humidity.

Cyclones are also called Hurricane in USA and Typhoon in Japan and Philippines

The Commutative property states that order does not matter. Multiplication and addition are commutative. The Commutative Property is a great strategy to use when adding multi-digit numbers. When I taught first grade, I taught counting up as an addition and subtraction strategy. But if students know that they can switch the order of the addends and start adding with the greater number FIRST, it makes counting up easier.

Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.

In nature, organisms exhibit various types of heterotrophic nutrition. They are as follows:

• Holozoic Nutrition
• Saprophytic Nutrition
• Parasitic Nutrition

Rhizobia is "the group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen. R hizobium is a genus of gram-negative, motile bacteria whose members are most notable for their ability to establish a symbiotic relationship with leguminous plants, such as peas, soybeans, and alfalfa. 

Pitcher plant derives nutrition just the way any other plant does . It takes water and minerals from the soil and food by photosynthesis. But the soil in which it grows doesn't has nitrogen so it uses the pitcher for killing small insects and then digesting them to derive nitrogen from the animal.

The humans are the most intelligent and developed species of our planet.That's why the human activities affect a lot to the environment.

Examples of these affects are:

1) Pollution is one of the most harmful effect of the human activities.

The Mughal Empire also witnessed the minting of coins under different rulers. Such coins provide general information about the chronology, the economic condition, rulers, etc. The coins during Babur’s reign, however, were largely regarded only for their monetary value. They lacked in the beauty and elegance of his successors, Akbar and Jahangir.

Mughal coins of different rulers depicted the portraits of the rulers, despite the prohibition imposed by Islam on display the images of humans or animals. Both Akbar and Jahangir minted coins with their portraits. Jahangir’s coins had the impression of the queen, Nur Jahan on one side with Jahangir’s image on the other side – Indicating the sharing of power between the emperor and his queen.
