Hi there!
In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.
Explanation:
Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.
Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>
(Sometimes, C-12 is also used)
Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
The answer youre looking for is C
Answer:
Plants use cellular respiration to harvest the energy stored in the molecules
Explanation:
Plants, just like any other living organisms, need energy to power their cellular processes. Therefore plants also perform cellular respiration by burning energy molecules like glucose. The difference with plants, unlike animals, is that they make their own glucose from abiotic factors like sunlight and carbon dioxide. They do this through the process of photosynthesis. Animals have to consume ready-made glucose that emanated (directly or indirectly)from plants.
