Answer:
Which of the following are involved in the cycling of nutrients in nature?
I.Bacteria
II.Plants
III.Earthworms
IV.Humans
Bacteria, Plants and Earthworms
Explanation:
Bacteria, Plants and Earthworms plays vital role im nutrients recycling in nature, earthworm does this during soil burrowing which enables the soil to mix together easily and allow nutrients to circulate. Plants also helps through the practice of mixed cropping and shifting cultivation whereby different plant is planted every year as the case maybe.
A, because it the constant variable
Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountainsproduced, and two continents sutured together. Continental collision is known only to occur on Earth.
Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and foldingcaused by collisions stops. The collision between India and Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). Collision between Gondwana and Laurasia to form Pangea occurred in a relatively brief interval, about 50 million years long.
Answer:
30meter per second
Explanation:
Given that
Distance = 3000 meters
Time = 100seconds
Speed = distance /time
Substituting the values
Speed = 3000/100
Speed = 30meter per second
The average speed needed to cover the travelling will be 30meter per second.
Hello!
The answer would be Alveoli
In humans, oxygen and carbon dioxide are exchanged in the blood within many small sacs called alveoli in the lungs. Alveoli provide a large surface area for gas exchange.
Hope this helped!
