Based on my observations, the earth rotates from west to east about the axis of rotation. The counter-clockwise rotation of the earth is as viewed from the North Pole star Polaris.
My observations supporting the counter-clockwise rotation of the earth are:
- The Sun rises in the east and sets in the west.
- All celestial objects including the stars and the moon rise in the east and set in the west.
The rotation is the result of the strong geomagnetic field of the earth. It is also responsible for the formation of day and night on the planet.

There is well over a million types of organisms on Earth.
Answer:
The correct answer is chemical energy from broken bonds is transformed into mechanical energy.
Explanation:
Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.
The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.
Answer:
The answer is 6.8 meters.
Explanation:
During the S phase of the cell replication, the DNA is doubled before the division of the cell which means that it is twice it's original length.
At 0.34 nanometers, 3 billion base pairs (3.000.000.000) comes up to 3.4 meters and during the S phase the length is doubled so it is 6.8 meters long.
I hope this answer helps.
Answer:
The correct answer is -
1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.
2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.
3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.
4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.
5. The cell wall of the plant is made of cellulose, a polymer of glucose units.
6. Eubacteria are considered to be the first living organism or form found on earth.
7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.
8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.
9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.
10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.
11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.
12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.
