Chimpanzees are more closely related while orangutans are the least closely related of the apes. Gorillas are in the middle of the two.
Answer:
Ecology can be described as the branch of biology which is related to the study of the interaction of an organism with other organisms and the environment. This study is important because both biotic and abiotic factors play a vital role in the existence of an organism. Abiotic factors such as soil type, food resources, water resources, amount of sunlight reflect which organisms will be able to live in an area. Biotic factors also influence the life of an organism just as the abiotic factors do.
Oxidative phosphorylation of the Aerobic respiration pathway.
Answer:
The light from Alpha Centauri system takes 4.37 light-years and Sirius star system takes 8.6 light-years to reach the Earth.
Explanation:
Light from millions of stars in more distant galaxies takes a long time to reach the Earth. Light travels at a speed of 300,000 kilometers per second. The time taken for light from these stars to reach the Earth is the distance to the star divided by the speed of the light. The distance traveled by light in one year is known as a light year and the distance to the stars that are farther away is expressed in light years.
The Sun is the closest star to the Earth and the sunlight takes about 8.3 minutes to reach on Earth. Apart from the Sun, the other stars closest to Sun include Alpha Centauri system and the Sirius star systems.
The Alpha Centauri system includes the stars Alpha Centauri A, Alpha Centauri B and Proxima Centauri. This system is 4.37 light-years away from the Earth. The third star, Proxima Centauri is 4.24 light-years away from the Earth i.e., the light from it takes 4.24 years to reach the Earth.
The Sirius star systems include Sirius A (Dog Star) and Sirius B. It is about 8.6 light years from Earth and so the light about 8.6 years to reach the Earth.

In line with other previous and contemporaneous proposals, in 1912 the meteorologist Alfred Wegener<span> amply described what he called continental drift, expanded in his 1915 book The Origin of Continents and Oceans and the scientific debate started that would end up fifty years later in the theory of plate tectonics.</span>
