Grass, grasshopper, frog, snake, fox, mountain lion.
Explanation:
Start with a producer, and keep on following the arrows until you reach the mountain lion, which is the last animal in this food web. The food chain that I mentioned above, has six components which is the longest one.
Answer: there is no permanent charge difference between one part of the molecule and another.
Explanation:
Explanation:
Since carbon cannot be produced or used up, the total amount of carbon in a closed ecosystem does not change
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
Answer:
It is double stranded DNA, and it could be from an eukaryote, a prokaryote or a virus.
Explanation:
You can rule out the possibility of the nucleic acid being RNA because of the presence of thymine, which is absent in RNA, and is replaced by the base Uracil. In double stranded DNA, guanine pairs with cytosine, and thymine pairs with adenine, so the proportions of A and T, as well as those of C and G, should be the same. This is consistent with the information given, so you can conclude that it is indeed double stranded (this can also be concluded simply by the fact that it is DNA, because this type of nucleic acid is always double stranded).
All types of organisms can have a DNA genome, so it could either belong to eukaryotes, prokaryotes, or viruses. If it were RNA, it would only be possible for it to belong to a virus, since they are the only ones that can have an RNA genome.
