The rainforest contains half of the Earth’s wildlife and at least two thirds of its plant species. It can hold great quantities
of water and is very important to the planet’s water cycle. Rainforests remove vast amounts of CO2 from the atmosphere and replace it with oxygen. Which of the following statements best summarize the above information about rainforests? a.
The majority of the planet’s oxygen is generated from the rainforest.
b.
Two-thirds of all plants originated from the rainforest.
c.
The rainforest is a major catalyst for the planet’s water cycle.
d.
The rainforest is important to life as a whole on the planet.
D) The rainforest is important to life as a whole on the planet.
Explanation:
While the other options are true, the statment states that it is not only one of them. It is stated that the rainforest provides a habitat for for 1/2 of Earth's wildlife and 2/3 of it's plants. This proves that 'B) Two-thirds of all plants originated from the rainforest' is correct. But, it also states that the rainforest removes CO2 from the air and puts oxygen back out, proving that 'A) The majority of the planet’s oxygen is generated from the rainforest,' is also correct. 'C) The rainforest is a major catalyst for the planet’s water cycle' is also proven true because it is said that the rainforest holds great quantities of water, making it very important to the planet's water cycle. These are all important to the planet, making 'D) The rainforest is important to life as a whole on the planet,' the most accurate statement.
A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy), with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.
Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment. For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
