Answer:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH (a measure of how acidic or basic the ocean is) drops. ... In fact, the shells of some animals are already dissolving in the more acidic seawater, and that's just one way that acidification may affect ocean life.
Change the wording a bit otherwise hoping ti helps
In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, i.e. observable trait. ... Such phenotypes are often expressed by the synthesis of proteins that control the organism's structure and development, or that act as enzymes catalyzing specific metabolic pathways.
I would say A, B D are the correct answers
