Anemia has many different causes, although iron deficiency and its resultant iron deficiency anemia are the most common causes in the Western world.

Explain: Not only is boiled water entirely devoid of oxygen but it is also lacking in essential minerals that the fish need for respiration, osmotic function, and virtually every other aspect of their life.

Explain: Craters on the Moon range in size from as small as one inch to over 100 miles across. Craters are formed when meteoroids hit the Moon. The moon’s mountains have changed little since they were formed billions of years ago. This is unlike the Earth’s mountains, which have changed greatly due to erosion by water which is not present on Moon’s surface.

For example, the Nile Crocodile lays approximately 40 eggs per year

Explain: All living things grow, even when they are mature. Immature organisms grow new cells to enable them to grow to their mature size. Without reproduction living, things would not survive more than one generation.

Explain: An aquarium air pump is a small device that forces low-pressure air through a tube into a fish tank for various purposes. These purposes usually include powering a sponge filter, a decorative ornament, add oxygen to the water, increases surface agitation, or add bubbles for decorative purpose.

Explain: Here the teacher is giving examples to a student which they have observed in their routine/everyday life. Thus here observation skills of students are being developed.

Explain: The process of lifting weights breaks down muscle tissue, so your body needs protein to repair the damaged tissue. Protein also provides the building blocks to help your muscles grow. Strategically adding protein to your diet will accelerate your overall strength, as well.

Explain: the First mixture of sand and salt is dissolved in water-salt gets dissolved whereas sand remains as such. Sand and filtrate containing sand are separated by filtration. The filtrate obtained is then evaporated off to remove water and get salt.

Explain: Aggression is the most serious of inappropriate behaviors and has the most serious consequences for both the student and those in his or her environment

Explain: Archimedes states that the upward force (buoyancy) exerted on a body immersed in a fluid is equal to the weight of the amount of fluid the body displaces, In other words for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus here in case of iron nail weight of water displaced is less than nail thus it sinks whereas in case of steel bowl weight of water displaced is more than bowl thus it floats.
