Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.

Answer:

C would be the incorrect statement.

Explanation:

When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.

Hope this helps :)

What percent of the energy consumed by the larvae became biomass that is now available to the next trophic level?
likoan [24]

Answer

         About 10% energy is converted to biomass from one trophic level to another trophic level.

Explanation

        Food chain is composed of different trophic level which are classified on the basis of their mood of food obtain. These include  

1. Producers (photosynthetic)

2. Primary consumers (herbivore)

3. secondary consumer (Carnivore)

4. Tertiary consumer (carnivore)

5.Quaternary consumer (Carnivore)

6. Decomposer  

                     As larvae are hatched by insects which belong to second trophic level.  About 90% of energy in food is lost at each trophic level. As move down the trophic level the number of organism also decreases in each trophic level. Therefore, energy transfer from one trophic level to another is like a pyramid.

Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently?
fomenos
The correct option is this: CELL 2 WILL THE ONE THAT WILL BE ABLE TO ELIMINATE WASTES MOST EFFICIENTLY. This is because it has the highest surface area to volume ratio which facilitates the exchange of materials between a cell and its environment.
The rate of diffusion of materials into and out of the cell depends on the surface area to volume ratio of the cell. The higher this ratio, the higher the rate of diffusion.
