<span>Each year, an average person in the United States is exposed to a radiation level of 360 mrem, which is the whole body equivalent dose from the background sources. Most of the radiation is the result from the natural sources. However, this value is also an indication of radiation caused by non-natural sources.</span>
Answer:
The correct answer would be D) In a population of herbivores, a change in the habitat provides leaves that are high up in the trees. The herbivores with longer necks can reach the leaves. They survive and reproduce. The herbivores, over time, have longer necks.
Natural selection is a gradual process which favors the survival and reproduction of organisms which have better adapted to the environment.
Adaptations or traits which favor the survival of the organisms in environment keep on passing from one generation to the next and with time theses traits get inherited in the population.
For example, in the above situation herbivores with short necks die as they could not reach the leaves that were high up in the trees. In contrast, long neck favors the survival of the organisms due to which only organisms with long necks survive and reproduce. With time, only organisms were left that had long necks.
<span>Unfortunately, we are not given with the choices in which we could have chosen our answers from. However, in order to determine the mass of an object, we use the balance or the weighing scale. Also, for the volume of the water by graduated cylinder. Then, we divide the mass by the volume. </span>

Options:
A) Cells require much less P to grow than N, so extra P will be used for ATP synthesis and result in a faster growth rate.
B) Cells will never consume all of the phosphate, because N is needed in higher quantities than P.
C) The final biomass of cells will be no different than if only 50% of the phosphate was provided.
D) The bacteria will import all of the ammonia to use for biosynthetic pathways.
Answer:A) Cells require much less P to grow than N, so extra P will be used for ATP synthesis and result in a faster growth rate.
Explanation: Chemoorganoheterophic Bacteria are bacteria which requires the supply of organic nutrients of Carbon and metabolic energy. If Ammonia and potassium are provided at equal amount or concentration, the least likely occurrence will be that
Cells require much less P(potassium) to grow than N(Nitrogen), so extra P(potassium) will be used for ATP synthesis and result in a faster growth rate. This is so because Chemoorganoheterophic Bacteria requires organic supply of nutrients in the form of Carbon and metabolic energy.
