Answer: I think it is A but if i had to pick a second option i would say B
Explanation: the reasoning behind this is option C has to do with machines and option D has to do with artificially growing cells. So therefore it has to be either A or B. hope this helps!
Water Cycle:
1. It is stored in the ground.
2. Evaporation, transportation, precipitation
3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.
4. It will usually end up in the same place, the ocean
5. Water levels rise, temperatures rise, CO2 in atmosphere increases
Carbon Cycle:
1. Carbon is important because it is one of the basic building blocks of life.
2. Trees, animals, grass, decomposition, combustion, fossil fuels
3. Carbon enters as photosynthesis.
4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.
6. By breathing in the oxygen from plants.
7. Two ways carbon return from animals into water is through cellular respiration and decomposition.
8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.
9. Deforestation reduces the capacity of forests to be carbon sinks.
Nitrogen Cycle:
1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.
2. It comes from lightning and is named nitrogen fixation.
3. Ammonification and then transitions into nitrification and then to assimilation.
Phosphorus Cycle:
1. It forms part of life sustaining molecules like DNA and RNA.
2. Phosphorus is never found in the atmosphere.
Answer:
Over population
Explanation:
With the coyotes gone, they're prey will have little to no predators. Without their numbers decreasing as quickly (because of the coyote population drop) they will be able to repopulate quicker and less of them will die. This will lead to over population.
Answer:
The right answer to this question is option A) island forms and mainland forms descended from common ancestors.
It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.
A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.
