The answer would be - It untwists the double helix and separates the two DNA strands. A helicase is an enzyme used to separate strands of a DNA double helix by breaking hydrogen bonds between annealed nucleotide bases.
Only the energy used for growth (33 J) is available to the next trophic level, because it is used to produce more biomass which can be consumed by the next trophic level.
Fungi act as decomposers on dead plants and animals so they don't vlog everything up! Hope this helps.
Answer:
Choice C: In mutualism, both organisms benefit, whereas commensalism benefits one organism without benefiting or harming the other
Explanation:
Symbiotic relationships describe the various ways organisms interact with each other. There are 5 common ones:
- Mutualism
- Commensalism
- Parasitism
- Predation
- Competition
We are asked to compare mutualism and commensalism, so we can focus on just these relationships.
In mutualism, <u>both organisms benefit</u>. An example is bees and flowers. Bees search for nectar in flowers and pollen from the flower attaches to the bee. As the bees fly, they spread the pollen and pollinate other flowers. The bees use the nectar to make honey and the flowers can reproduce.
In commensalism, <u>one organism benefits while the other organism is not harmed or benefitted</u>. An example is barnacles and whales. Barnacles attach to whales and they can move around and find food. The barnacle receives transportation and food. The whale remains unharmed but does not benefit.
The correct answer is <u>Choice C: In mutualism, both organisms benefit, whereas commensalism benefits one organism without benefiting or harming the other. </u>
