Yes. the nucleotides are A, T, G, and C. A and T pair up and G and C pair up. For instance, if your known strand is AGTCAG then the second strand would have to be TCAGTC. Also, if there is a U in the strand, it takes the place of T. so the original strand would be AGTCAG and the unknown would have to be UCAGUC.
C) White light is least useful for photosynthesis in terrestrial plants. Green would be more useful because that's their usual color.
A herbivore is an animals that is meant to eat plants like grass so the grasshopper or locust would be considered the correct answer.
For example bees they use wax to build shelter
"Flower" is the producer here!!
Hope this helps!
