Because our eyes see what's reflected not absorbed. Leaves contain chlorophyll which contains a pigment of green that absorbs red and blue wavelengths, while reflecting green.
Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
I believe the answer would be D. If a plant were to have poisonous parts it could me the possibility that a child could become seriously ill.
The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.
Explanation:
The bacteria rapidly divide, the chances of mutation in the gene increases manifold.
The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.
These bacteria which survived and proliferated as the environment was in their favour.
Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.
Plant cells have a rectangular shape and a cell wall, while animal cells have a circular shape and no cell wall
