cells that never go through cell division.

only found in embryos.

Which best explains why muscle cells are different from blood cells?

Muscle cells are produced by the brain, but blood cells are produced by the heart.

Different genes are activated in muscle cells than in blood cells.

Muscles cells experience different environmental influences than blood cells.

What is the difference between embryonic stem cells and adult stem cells?

Embryonic stem cells can differentiate into more cell types than adult stem cells

Adult stem cells are pluripotent, just like embryonic stem cells

Adult stem cells can differentiate into more cell types than embryonic stem cells

Adult stem cells grow bigger than embryonic stem cells

What best describes Induced Pluripotent Stem (IPS) Cells?

Cells that come from sperm cells

Cells that come from egg cells

Turning body cells (somatic) cells, like skin cells, back into stem cells

Turning they zygote into stem cells

13.

Why do we need meiosis?

To double the number of chromosomes going into sex cells

To halve the number of chromosomes going into sex cells

To triple the number of chromosomes going into sex cells

To not change the number of chromosomes going into sex cells

14.

Meiosis makes sperm and egg cells. In humans, sperm and egg cells each have _____ chromosomes. Therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with _____ chromosomes.

23, 46

46, 23

2, 4

15.

What is a difference between mitosis and meiosis? Mark ALL that apply!

Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.

Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.

Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.

Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
