Explanation

Every planet in our solar system except for Venus and Uranus rotates counter-clockwise as seen from above the North Pole; that is to say, from west to east.

This is the same direction in which all the planets orbit the sun. Uranus was likely hit by a very large planetoid early in its history, causing it to rotate "on its side," 90 degrees away from its orbital motion.

Venus rotates backwards compared to the other planets, also likely due to an early asteroid hit which disturbed its original rotation.

Explanation

Sunlight entering the water may travel about 1,000 meters into the ocean under the right conditions,

but there is rarely any significant light beyond 200 meters.

The ocean is divided into three zones based on depth and light level.

The upper 200 meters of the ocean is called the euphotic, or "sunlight," zone

Explanation

Malaria is caused by a female mosquito, Anopheles; while dengue is caused by Aedes aegypti mosquito.

Explanation

Vitamin A deficiency can cause both loss of appetite and night blindness.

It is also known to increase susceptibility to infections, including those in the throat. 

Night blindness

This is one of the earliest signs of vitamin A deficiency.

It is the inability to see well in low-light conditions, which is caused by the lack of a specific pigment needed for the retina to function properly. 

Loss of appetite

Vitamin A is involved in the health of the receptors for taste and smell.

When vitamin A is deficient, these senses can be altered, which leads to a reduced appetite and difficulty consuming enough nutrients. 

Explanation

How does the Navstar GPS work for different applications? (5)

The Navstar GPS works by using a constellation of satellites that send signals to GPS receivers on the ground, allowing them to calculate precise location coordinates.

It is used in various applications like navigation, mapping, surveying, military operations, and location tracking for vehicles and personal devices.
