Usually blood used in blood transfusions contains very little of the donors plasma.
Answer:
C. Multi-celled eukaryotic organisms began to diversify
Explanation:
The Proterozoic is an eon in which numerous important things occurred. There were multiple organisms that appeared in this eon. They were able to perform the process of photosynthesis which resulted in gradual pilling up of oxygen into the atmosphere, thus changing the composition of the atmosphere, and setting up the terrain for the future development of other organisms. It is an eon though in which there were only single-celled organisms, while the diversification of multi-celled eukaryotic organisms occurred in the next eon, the Phanerozoic.
Answer:
ATP
Explanation:
We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.
AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.

Origin of species by means of natural selection
Answer:
Plant grass and shrubs. Bare soil is easily swept away by wind and water, the two main causes of erosion. Plant roots hold the soil together, while their leaves block rain and stop it breaking the soil apart.[1] X Trustworthy Source Virginia Cooperation Extension Publications and Educational resources from Virginia Tech and Virginia State University Go to source Turf, ornamental grass,
