Well we know that a microscope is used to see things we cant see like organism's so they can study those small creatures and learn
Answer: option A - Predators would initially avoid king snakes but soon learn to attack and eat them.
Explanation:
Though, coral snakes have never been present; some predators are LIKELY to have just migrated into new territories (leaving previous territories due to Coral snake ferocity) and as a result will INITIALLY avoid king snakes but later (due to limited food chain) approach King snakes for food
Answer:
The sporophyte body comprises a long stalk, called a seta, and a capsule capped by a cap called the operculum. The capsule and operculum are in turn sheathed by a haploid calyptra which is the remains of the archegonial venter. The calyptra usually falls off when the capsule is mature.
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
It is the ribosomes that assist tRNA
