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.
Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.
The answer is <span>Determine why the beetle is eating one tree but not the other.
The botanist should first d</span><span>etermine why the beetle is eating one tree but not the other. By determining that, he will understand what connects beetle to the tree. This will also explain does the tree benefits from this interaction or not.</span>
