The answer is, d. consists of circular DNA molecule . The circular DNA is found in bacterias and archeas (which are prokaryotic organisms). The picture shows bacterial chromosome.
Despite their frequency in the intertidal zone, in tide pools, sea urchins can be found at many different depths and in any habitats. They can also be found in nearly any ocean temperature. Sea urchins inhabit the polar seas as well as the warm tropics.
Answer:
Enzymes are proteins in composition which are a very essential component of the metabolic reactions in the living organisms.
The properties of enzymes allow the enzymes to be used as a reaction catalyst which increases the speed of the reaction.
The enzymes lower the threshold energy of the chemical reaction and thus increases the rate of reaction.
The enzyme catalyses very complex reactions like a breakdown of complex biomolecules as well as the formation of complex biomolecules.
The active sites are present on the enzymes which bind the substrate molecule and increases the pace of reaction.
Answer:
The correct answer is - mutualistic.
Explanation:
The symbiosis or relationship between the bacterium xenorhabdus namtophilia and Steinernema carpocapsae, the nematode host is known as mutualistic or the cooperation in between them. Both the organisms live in a symbiosis in which both are benefited.
The nematode lives free till the early infective juvenile stage only. Bacterium present in both conditions as individual and with the symbiosis of the host.
Thus, the correct answer is - mutualistic.
