A group of ants escaped from a picnic basket carried to the top of a mountain and thrived in this area where there were no other
ants. Many years later descendants of these ants crawled into a picnic basket on the mountain and traveled back to the valley from which their ancestors had come. Which of these observations would cause you to conclude that the ants on top of the mountain had become a different species from those in the valley? A) The mountain ants and valley ants were different colors.
B) The mountain ants and valley ants were different sizes.
C) The mountain ants ate different food than the valley ants.
D) The mountain ants could not mate with the valley ants
Answer: Option D) The mountain ants could not mate with the valley ants
Explanation:
One distinguishing feature of species is their ability to mate with one another.
For example the mountain ants can mate freely with another, so also the valley ants because each belongs to the same specie.
In constrast, the valley ants cannot mate with the mountain ants due to years of reproductive isolation between them, thus resulting in both being different species ( Sympatric species, living in the same territory, but unable to interbreed)
Fungi are different from plants because fungi do not photosynthesize and plants do. FUngi do not have chlorophyll, but plants do. The fungi absorb nutrients from organic wastes due to decomposition process without light. Plants absorb nutrients from organic matter and transform them into food through photosynthesis process.
The answer is: [B]: They use different nucleotide bases. ______________________________________________________ Specifically, DNA replication uses thymine; whereas transcription uses uracil. _______________________________________________________
