Answer: b. chemoautotrophs
Explanation: chemoautotrophs are organisms that obtain energy, molecules, water by the oxidation of electron donors in their environments. Chemoautotrophs are able to synthesize their own organic molecules from inorganic sources. They are different from phototrophs who requires sunlight to make their own food
Scientists will look for evidence like similar body or skeleton structures, internal similarities or maybe sometimes the whole heirarchy to confirm that two speices are closely related to each other.
For example ; in birds, scientists will look for type of feathers, body structure, beaks to confirm the similarity of two birds.
Answer:
The correct answer is (b)-False
Explanation:
Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.
Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.
Therefore bacteria do not undergo meiosis or mitosis.
