Answer: B. participate in the hydrologic cycle
Explanation: Residence time of water is the rate of water in a water reservoir such as the ocean or the atmosphere divided by how fast more water is added to it or lost from it.
While residence time is thousands of years in oceans, water in the atmosphere has a short residence time of abut 10 – 11 days. This allows it to participate in the hydrologic cycle which includes evaporation and precipitation. Water in the atmosphere precipitates as snow or rain, returning to other water reservoirs.
The mantle is a like a plastic looking layer of the earth
If the rocks are layered on a fine scale
If the rocks are homogenous
If the crystals in the rock vary in size
During the light-independent reaction, carbon dioxide is fixed by adding it to a 3-carbon compound
Answer: Option B
<u>Explanation:</u>
In the first stage of ''Calvin cycle'', light independent reactions are started and the carbon dioxide gets fixed from a molecule that does not have light to a molecule having light and in the second stage where carbon compound like ATP and NADPH gets reduced into a three carbon compound. This is done for converting energy in to a chemical bond energy for example in a glucose.
Answer:
Life began on Earth at least 3.5 to 4 billion years ago, and it has been evolving ever since. At first, all living things on Earth were simple, single-celled organisms. Much later, the first multicellular organisms evolved, and after that, Earth's biodiversity greatly increased.
