A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA
damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

  • <em>the G_0 phase,</em>
  • <em>the G_1 phase,</em>
  • <em>the S phase; and</em>
  • <em>the G_2 phase</em>.

The G_0 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the G_1 phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the G_2 phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of G_2 phase.

The correct option is b.

EPA scientists performed an experiment where coal was
iris [78.8K]

The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.

<h3>What is Reaction time?</h3>

This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.

Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.

Answer:

Tendon or a connective tissue

Explanation:

Tendons are a type of connective tissue that attaches muscle to bones. They are strong, fibrous and flexible. They also attach muscles to other organs. Tendons have a high tensile strength which is useful to withstand muscle contractions. They are made up of bundles of connective tissue that contribute to its strength.
