Answer:
<u>C</u>
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.
Answer:
The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.
Explanation:
There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.
