Cys-tRNACys (Cys-charged tRNACys) can be converted to Ala-tRNACys (Ala-charged tRNACys) by catalytic reduction. Assume that Ala-tRNACys is added into a functional in vitro translation system that contains all the essential components for translation, including: ribosomes, all tRNAs excluding tRNACys, all amino acids, mRNA encoding for a given protein, and all other essential cofactors / enzymes required for translation. Where in the newly synthesized protein would Ala be incorporated? a. at the positions where Ala and Cys normally occur for this protein.
b. at the positions where Ala normally occurs for this protein.
c. at the positions where Cys normally occurs for this protein.
d. at the positions where Ala-Cys dipeptides normally occur for this protein.
e. ala won't be incorporated, because Ala-TRNACys won't be recognized by the ribosome.

Alichen is an organism that structurally appears to be a single organism. but a lichen is actually two different organisms—a fungus and green algae—living together as one organism. the fungal partner derives its nutrition from the photosynthesizing algae. how does a lichen differ in its photosynthetic activity from elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? a. in lichens, the fungi photosynthesize on their own, while elysia chlorotica forms a relationship with a photosynthesizing plant. b. in lichens, the relationship with the algae lasts throughout the life cycle, but in elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. c. lichens can photosynthesize only because of the living algal partner, while elysia chlorotica incorporates chloroplasts from algae into its cells. d. in lichens, the association between the fungi and algae is permanent, while elysia chlorotica associates with a photosynthesizing organism only when it requires food.

What adaptations can prey use to avoid predation

Ecosystems involve living organisms interacting with non-living things in a productive way; how is photosynthesis an example of this? answer, i will give brainiest to first person to get it right.
