Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.
Homeostasis is very important and your body function or the enzymes here because of your body being in homeostasis. If increase or decrease in temp, your body will halt all processes and try to readjust your body back to normal first because if not, then a lot of other processes would be affected negatively as well and you could potentially get ill.
The pentose sugar on RNA is called ribose. (a trick to remember it is that the "R" in RNA stands for ribo)
Hope this helps :)
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
A. Carbon dioxide levels are increasing in the air, and the ocean is absorbing carbon dioxide; atmospheric levels are increasing so much that the increase is still apparent even with increasing absorption of carbon dioxide by the ocean. Research conducted by the University of Miami (UM) has found that the waters of the North Atlantic absorbed 50 percent more carbon dioxide of human origin in the last ten years than in the past decade.
The results of the study show the impact that the burning of fossil fuels has had on the world's oceans in the last ten years
