Gregor Mendel, the father of genetics, made his great discoveries by simplifying problems. Instead of studying complicated characters with which he might ask what is “more or less” inherited, he chose to study simple characters with which he could see whether it was inherited or not because there were only two clear, and distinct possibilities.
Because, photoautotrophs serves as their carbon sources.
Chemoheterotrophic bacteria are those bacteria that are incapable of producing their own food, they depend on photoautotrophs, which are capable of making their own food by trapping energy from the sun. Thus, photoautotrophs serves as source of food for the chemoheterotrophic bacteria.
Answer:
(D). lungs
Explanation:
Cladograms are diagrams that show cladistic relationship between organisms of different species on the basis of their characteristics. The cladograms may include characteristics to make two organisms different from each other.
In given cladogram, characteristic that separates bony fish from amphibians is 'lungs', as lungs are absent in bony fishes, while present in amphibians.
Thus, the correct answer is option (D).
