Answer:

"Pro" means "before," and prokaryotes have DNA in a freely floating ring that is not encased in a nucleus. "Eu" means "true," and eukaryotes have DNA arranged in chromosomes and encased in a nucleus. Fossil evidence indicates that prokaryotic cells first existed on the earth, prior to the arrival of the eukaryotes.

Mitosis can occur in both haploid and diploid cells, but meiosis cannot occur in haploid cells. Why not?.
allochka39001 [22]

Mitosis can occur in both haploid and diploid cells because it is equational division where the number of chromosomes remain the same after division. But meiosis cannot happen in haploid cells because it is reductional division and haploid cells do not have any extra copy of chromosomes to be halved.

Mitosis is the cell division where the number of chromosomes do not change after cell division. It usually happens in the somatic cells of the body. Cancer cells also undergo mitosis

Meiosis is the cell division where the number of chromosomes are halved after cell division. The process of meiosis occurs in two phases: meiosis I and meiosis II. The germ cells of the body undergo meiosis.

How does sound travel ? How does the medium the sound travels through help determine the speed of sound ?
Andreas93 [3]

The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.
