Explanation:
A- meiosis
B- zygote
Cell B is described as diploid cells because two haploid cells n(40) fuses together to form diploid cell 2n(80)
DNA is made up of deoxyribose sugar while mRNa is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double stranded while mRNA is single stranded.
Hope this is helped ;)
By low temperature, it can melt. High pressure will raise the melting point of the rock.
