It is a behavioral adaptation.
There are three types of adaptations:
Structural - body parts that help it survive (e.g. color, size, shape)
Physiological - systems present in an organism that allow it a special feature (e.g. venom, skin color changes)
Behavioral - an action that allows the organism to better survive
Freshwater, ocean water, and terristrial.
There are three broad categories of ecosystems based on their general environment, as those that were mentioned above. Within these broad categories are individual ecosystem types based on the organisms present and the type of environmental habitat.
Answer:
Arginine
Explanation:
A specific genetic code specifies a particular amino acid. One amino acid can be encoded by more than one genetic code.
When a particular amino acid is encoded by more than one genetic code, all the genetic code for that amino acid mostly share common first two bases and differ from each other in the last base. This allows the same tRNA with particular anticodon to read all the possible genetic code for that amino acid and to serve as a carrier due to wobble base pairing.
Given that code "CGG" specifies arginine, the code "CGA" should also specify "arginine" since both differ with respect to the last base only.
Answer: acetyl group, methyl group, or phosphate group
Explanation Basically different modification can occur to the tail regions of histone .This includes addition of the groups listed above
