After cell division (mitosis) how does the genetic code of the newly
Harrizon [31]

Answer:

Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.

Explanation:

Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:

G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.

S is the period of DNA synthesis, where cells replicate their chromosomes.

G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.

M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.

1. Zach made a chart to show how many mm his plant grew each week for 7 weeks. Each block equals 5 mm of growth. How tall is the
yulyashka [42]

The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Answer:

The correct answer is - 13.5 cm.

Explanation:

According to the details of the blocks, the number of blocks each week as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Adding total blocks would be :

2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks

Each block equals 5 mm of growth.

Then, 27 x 5 = 135 mm

135mm = 13.5 cm

Thus, the correct answer is : 13.5 cm
