Answer:
the second choice is really the only on that makes sense,
Explanation:
I'm not really sure that plants need rocks but it can't be the third answer choice because soil is made up of cells and microorganisms. Plants can photosynthesize but animals (the mocking jay) cannot. and for the last choice water and sunlight aren't any type of organism, they are abiotic.
The answer is carbon dating. This method is based on the fact that a radioactive isotope of carbon is constantly being created in the atmosphere due to the interaction of cosmic rays with atmospheric nitrogen. This radioactive carbon combines with oxygen to form radioactive carbon dioxide. This carbon dioxide enters the food web, first through plants through photosynthesis, and then to the primary and secondary consumer levels. Therefore, animal and plant material will contain a portion of this radioactive carbon. This particular form of carbon has a half life of <span>5,730 years due to radioactive decay. So this is how scientists are able to date the age of biological material.</span>
Answer:
True
Explanation:
Yes, the amount of precipitation required by a lake to increase the water content by 2 feet, can be understood in scientific way.
We know that lake water content depends on some factors such as amount of precipitation, amount of evaporation, the dimensions and size of the lake, the depth of lake, speed of the water flow. Therefore, if we know exact figures about all such factors, or if we measure such factors, it will give a more proper answer in a scientific and logical way.
Hope it helps :)
<span>Liver, I think thats one of them im not sure though</span>
