An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately
Answer:
At 0hr it was 200 bacteria
At 1 hr it doubled and was 400
Means: at every 1 hr the population of the bacteria doubles
400 bacteria = 1hr
2000 bacteria = X
X = 2000 × 1 / 400
X = 5 hrs
True guards cells open during the day
Answer:
The correct answer is A). The two forms are observed to interbreed successfully where their habitats overlap.
Explanation:
According to the biological species concept, the members in a population which interbreed with each other and produce viable offsprings comes under the same species. This classification does not involve morphology because even organisms having the same morphology can be of different species because they do not interbreed with each other in nature.
So here myrtle warbler and Audubon's warbler must be found interbreeding with each other and producing offsprings which have good survival rate and reproductive capability so this information might allowed scientists to reclassify these bird in the same species because only members of same species interbreed with each other. So the correct answer is A.
