Both are 50%, this is because Rr is dominant in a purple stem and rr is recessive in a green stem. By crossing these plants Rxr= Rr and rxr= rr.
Humans caused damaged by all the pollution in the earth atmosphere with is making global warming it changes by how much pullution is going into the atmosphere
The correct answer here is certainly B. They allow scientists to perform new investigations and test new ideas they may not have been able to do in the past because scientists have been able to do the other 3 options without modern technology.
I would say excretion since that means the process of expelling waste matter.
1) Adenosine triphosphate (ATP) is thought of as the "molecular currency" for energy transfer within the cell. Function: ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell and Cells store energy in the form of ATP; cells make 36 ATP through cellular respiration.
2) Energy is normally stored long term as carbohydrate, in plants the storage polymer is starch whereas in animals the storage polymer is glycogen. Both of these are formed from the monomer alpha-glucose (C6H12O6). When energy is required by the cell, storage polymers are hydrolysed to yield glucose molecules, which are the starting point of respiration, a series of chemical regions yielding ATP, the universal cellular energy release molecule.
