Reproductive isolation refers to the situation where different species live in the same area, but properties of individuals prevent them from interbreeding. the thing which stop species or groups of organisms reproducing sexually are called isolating mechanisms. hope this helps
Answer:
The correct answer is d. eukaryotes almost always produce polycistronic mRNA
Explanation:
mRNA can be polycistronic or monocistronic. A monocistronic mRNA contains the information of one gene only so a monocistronic mRNA code only one protein at a time but a polycistronic mRNA can code for multiple proteins at a time.
In eukaryotes, one transcriptional unit carries the information of only one protein so eukaryotes produce monocistronic mRNA but some eukaryotes are capable of having polycistronic mRNA.
In prokaryotes, many genes are transcribed as a unit to produce multiple proteins so prokaryotes produce polycistronic mRNA. Therefore the statement which is not true is d. eukaryotes almost always produce polycistronic mRNA.
Answer:
cooperation
Explanation:
Cooperation occurs when living things of different species work together to benefit themselves. The interaction between a bee and a flower is a symbiotic relationship. A symbiotic relationship between two living things is one in which at least one of the parties benefits. The relationship between the bee and the flower is a mutual one because both parties benefit.
While the pollen and nectar serve as food for the bees, the spread of the pollen to other plants assist in the reproduction process.
