Answer:
a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.
Explanation:
Anabolic pathway refers to the metabolic processes that synthesize intricate molecules from simpler ones, generally through condensation (where monomers are linked covalently, generating water as a by-product). It demands energy for forming new bonds, which indicates that it is endergonic.
Conversely, the catabolic pathway pertains to metabolic reactions that dismantle complex moleculesinto simpler components, typically through hydrolysis (where water is utilized to sever bonds within the polymer). It liberates energy during the bond-breaking process, this indicates it is exergonic.
Based on this information we can ascertain that the correct answer is a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.

Organisms vie for essential resources such as air, water, food, and space within an ecosystem. This competition can occur both among individuals of the same species (intraspecific) and between different species (interspecific). It is a crucial subject in ecology. The struggle for food, in particular, exemplifies this interaction, as seen in the competition for food between hyenas and lions within their ecosystem.
Answer:
DNA can be likened to a zipper. As with a zipper, the two DNA strands are connected by hydrogen bonds formed between nucleotides. When replication occurs, the twisting of the strands unravels, akin to opening a zipper. The strands separate, just as the teeth of a zipper do when it is unzipped. Each strand is capable of generating a new strand.
However, just like improper handling or wear can damage a zipper, DNA replication can also introduce errors that may result in mutations.
