The answer is D, for when one tropic level is eaten by the tropic level above it, the tropic level is supporting the higher one. I. E. Rabbits are supported by the grass because rabbits eat the grass. Also, the grass population would be larger than rabbits, the rabbits larger than snakes, so on and so forth, so B is ruled out. B states that each population is larger than the one BEFORE it, but there is no way there would be more rabbits than grass. Also, there are both herbivores and carnivores in the food chain, so A and C are out. The best answer is D.
Answer:
Polytene chromosomes may be defined as the giant chromosomes that contain alternate dark and light bands when view under the microscope. These chromosomes are found in the salivary gland of Drosophila.
These glands are functionally highly active and contain thousand of DNA strands. These chromosomes are aligned parallel with each other as the replication is normal but the cells are unable to separate and fails to undergo the process of cytokinesis.

Answer:
<em>S. aureus</em> is spherical and arranged in clusters
Explanation:
<em>Staphylococcus aureus </em>is a gram positive bacteria that forms a part of our body microbiota. It is usually found on skin and in upper respiratory tract. The genus name of this organism is <em>Staphylococcus </em>which tells a lot about its morphology. Cocci or coccus is the name given to bacteria who appear spherical. Staph points out to their arrangement which is in clusters. Had it been <em>Streptococcus</em>, it would mean that the bacteria were spherical and arranged in long chains. Similarly, <em>Diplococcus</em> would mean that the bacteria were spherical and arranged in groups of two. Hence from the name <em>Staphylococcus aureus </em> we can say that it is spherical and arranged in clusters.
