Assuming a 10% trophic efficiency, the herbivore (primary consumer) will get 10% of the producer energy. Then, the second consumer that eat the herbivore will get 10% of the primary consumer energy, so it is 10%*10%= 1% of the primary producers.
Then, the t<span>ertiary consumer should get 0.1% of the primary producers' energy.</span>
The answer would be:

Here's a little more about gene regulation:
Gene regulation as mentioned already, is the process of turning genes on and off. In multicellular organisms, the different cells have the same DNA in them but through gene regulation, different sets of genes are expressed. The genes that are expressed determine the function and appearance of the cell.
Answer:
semipermeable
Explanation:
semipermeable membrane, such as plasma membrane, only allows only some materials such as oxygen—small material. other <em>stuff</em><em> </em>like starch couldn't get in.
Answer:
The correct answers are- a) In the deformed mice, somatic cells but not germ cells were mutated and d) The toxic chemical affects development but is not mutagenic.
Explanation:
Mutation in the somatic cells do not pass in the offsprings and the only mutation in the germ cells can pass to the offspring because offspring are produced by the fertilization between different germ cells. Somatic cell mutation can only cause deformation in individuals but their offspring will be like normal offsprings.
The other cause may be that the toxic chemical used don't cause any mutation but just affect the development of mice so in this case genetic material will remain in normal state in deformed mouse and they will able to produce normal offsprings. So the right answer is a and d.
Answer:
The correct answer is B.
Explanation:
Mitosis usually results in two identical daughter cells, whereas meiosis results in four sex cells.
