The answer would be C, it would be more difficult for DNA to unzip. Hydrogen bonds are strong, but easy to separate.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Is there more information?
They would eventually die out because they don’t have the correct adaptations, or they could breed together to make more of the adapted versions. Basically survival of the fittest
Answer:
It was it <u>harmful</u> for the <em>Chthamalus</em> barnacle to add the <em>Balanus</em> barnacle.
Explanation:
The principle of competitive exclusion says that two different species that share the same niche can not live in the same place. If these species have the same requirements, they can not coexist. Two species can not coexist indefinitely on the bases of the same limited resource.
When two competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species.
In the exposed example, Chthalamus can live in the upper intertidal zone, where Balanus can not live because they can not tolerate desiccation. Balanus live in the lower intertidal zone, where Chthalamus can not live because of its vulnerability to predation. But these two species compete for the middle intertidal zone, where they can both live. Balanus excludes Chthalamus because the first species is much bigger and grows faster than the second one. So the middle intertidal zone is only inhabited by Balanus.
The area occupied by Chthalamus is smaller in the presence of Balanus. In the absence of Balanus, Chthalamus can live in a bigger area, occupying the middle intertidal zone.
