Answer:
The elements are hydrogen, oxygen, nitrogen, and carbon.
Explanation:
Together, they constitute more than 99% of the mass in most cells and are the lightest elements able to create one, two, three, and four bonds correspondingly.
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.

Answer:
Option (A).
Explanation:
The lac operon system in bacteria elucidates the process of lactose metabolism within the cell. The initial operon system was identified by Jacob and Monod. An operon is characterized as a cluster of genes transcribed together as a single RNA unit.
When both glucose and lactose are available in the media, the bacterium favors metabolizing glucose. The presence of glucose is recognized by the bacterial cell as the CAP-cAMP complex is essential for transcription, and its levels are reduced in glucose's presence. This mechanism effectively halts the transcription of lactose genes even when lactose is available.
Consequently, the right answer is option (A).
In response to the claim, you could refer to a principle of cell theory, stating that cells are the fundamental unit of life, and critically, all cells arise from pre-existing living cells.
