What work sheet? I'm great in Biology!
Answer:
1) In mitosis, a single cell is divided into two daughter cells while in meiosis a single cell is divided into four daughter cells.
2) Mitosis occurs in body cells in which sperm and egg cells combine and make a diploid zygote while meiosis are present in sex cells in which haploid cells are produced.
3) In mitosis, the number of chromosome is double i. e. Diploid while in meiosis the number of chromosome is half i. e. haploid.
Answer:
either B or D because at the end Whilst the ultimate outcome of the lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription and physical processes.
Answer:
The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
