Which best illustrates a result of a natural selection?

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
