What enzyme works to add dna to ends of chromosomes in rapidly dividing cells such as those found in an embryo

The correct answer is: telomerase.

Telomeres (ends of chromosomes) shorten during the cell division. Telomerase is an enzyme that has ability to extend the telomeres of chromosomes by adding nucleotides so, they reverse telomere shortening. Telomerase is an RNA-dependent DNA polymerase (it uses RNA as a template for its functioning). Telomerase is active in germ cells because these cells often undergo cell division.

i think its the first one

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
