<span>The right anwer is (b). Indeed, some scientists consider viruses as non-living because viruses do not undergo mitosis, which is the usual way living cells reproduce themselves. On the contrary, viruses inoculate their genetic material in a host cell in such a way to force the cell to make a copy of the virus DNA, thus making more viruses, that then kill the host cell and disseminate themselves. In practice the viruses exploits the replication tools of the living cells to replicate themselves, since they lack the machinery and also they lack something resembling cell metabolism, i.e., they do not "eat" or "grow".</span>
Answer: The rate of diffusion is directly proportional to the molecular weight of any gaseous substance
Explanation:
According to Graham's law of diffusion, the rate of diffusion is directly proportional to the molecular weight of the gaseous substance.
Hence, the lighter the molecular weight, the faster the diffusion.
Answer:
enable capillarity
Explanation:
It is well known that water tends to adhere to the walls of the vessel in which it is contained. This is due to the force of adhesion which is defined as the force of attraction between unlike molecules. Cohesion is defined as the force of attraction between like molecules. In the case of a plant, cohesion of water molecules in the xylem vessels prevents the water column from breaking. The forces of adhesion, surface tension and cohesion are the basis of capillarity,that is, the rise of liquids in capillary tubes.
Answer:
The rain forest animals reqire much water
Explanation:
They differ because the desert animals are likely to require less water.
<span>This is the phosphorus and carbon cycle. By breaking down dead carbon-containing objects and returning them to the soil, these bacteria are able to allow the nutrients to be re-used by future generations of plants and animals, continuing the cycle.</span>
