Which statement is true fir some photosynthesizing animals? a. some carry out photosynthesis through the chloroplasts they incorporate into their cells. b. they conduct light-dependent reactions and the calvin cycle in the mitochondriac. they're true autotrophs because they can photosynthesize on their ownd. they're single-celled organisms that move like animals, but they contain chloroplasts

a. some carry out photosynthesis through the chloroplasts they incorporate into their cells.

Explanation:

Elysia chlorotica is a marine mollusk. Also called sea slug, it feeds on yellow-green algae, Vaucheria. The slug retains the chloroplasts from the algal cells and inserts them into the cells of the lining of its digestive tract.

The presence of chloroplasts allows these cells to absorb the sunlight and perform the photosynthesis to produce glucose. Therefore, incorporation of chloroplasts from their food algae allows the otherwise heterotrophic sea slug to perform the process of photosynthesis.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
