Section 4.2: Cell Division

Exercise 11
Step 1
1 of 2
The answer is 1. When undergoing cloning, the cells also undergo mitosis. The precise division of the genetic material during mitosis is important so that every fresh cell gets a perfect duplicate of the genetic information.

The answer is 4. Mitosis is a type of cell division that has the same number of daughter cells as well as the same number of chromosomes. This type of cell division usually occurs in tissues that need regeneration.

Step 1

the answer is 1. Meiosis is a type of cell division wherein the resulting cell are four daughter cells which does not have the same number of chromosomes but rather only half of the parent cells. This usually occurs during the formation of gametes and spores.

Exercise 17
Step 1

The answer is 1. Asexual reproduction requires only one parent and have the same genetic combination as the parent. The resulting offspring may have different variations. In asexual reproduction. the usual type of cell division is mitosis.

Exercise 18
Result

The final number of cells would be four with 2 chromosomes for each. Meiosis is a type of cell division wherein the resulting cell are four daughter cells which do not have the same number of chromosomes but rather only half of the parent cells. This usually occurs during the formation of gametes and spores.
Exercise 19
Step 1
1 of 2
The answer is 1. Orangutans undergo sexual reproduction. Sexual reproduction is the process of making an offspring using an egg cell and a sperm cell. The egg and sperm cell come in contact with one another and then combine the genetic material of both egg cell from the mother and sperm cell from the father.

Exercise 20
Step 1
1 of 2
The answer is 1. The stages of mitosis are as follows:
1. Prophase – the nucleolus and envelope disappear and chromosomes are coiled.
2. Metaphase – chromosomes are placed equally away from the poles
3. Anaphase – starts when a pair of chromatids separate and chromosomes are formed at the end.
4. Telophase – chromosomes are uncoiled and nucleolus reforms.

Exercise 26
Step 1
1 of 2
The answer is 3. Meiosis is a type of cell division wherein the resulting cell are four daughter cells which does not have the same number of chromosomes but rather only half of the parent cells. This usually occurs during the formation of gametes and spores. If meiosis failed to occur, the result will still be the same as the parent cell.
