Microbial population growth is represented bu the graph. based on this model we would expect the population growth of this colony to a) be exponential

B

Explanation:

The answer is change over time b/c if you look at the graph it doesn't stay the same throughout.

change over time   B

Explanation:

Based on the graph, we would expect the bacterial population to change over time. Initially, growth is exponential. The population curve then levels off; that probably represents the carrying capacity for the population. The curve then turns downward indicating a decline in the microbial population. The decline can be attributed to many factors, both density-dependent and density-independent.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
