Each cell that enters the cell cycle contains sister chromatids<br><br> a. True<br> b. False
Snowcat [4.5K]

Answer:

b. false

Explanation:

The cell cycle consists of three states: Interphase, Cell division (mitosis) and Resting.

Interphase is composed of phases G1, S and G2. during this state the cell replicates the genetic material of its chromosomes to prepare itself for cell division

In G1 the cell synthesizes mRNA and proteins that the cell will need during mitosis.

In S the cell replicates the genetic material of its chromosomes to prepare itself for cell division. At the end of this phase each chromosome is composed of two sister chromatides.

In G2 the cell grows and and more proteins synthesized  for mitosis.

Mitosis is the production of two daughter cells from a sinlge one. During the entire mitosis the chromosomes are duplicated in the cell until finally, the genetic material is distributed in two cells after cytokinesis.

According to the above, it can be seen that  the chromosomes in a cell that is in the cell cycle do not necessarily have sister chromatids. For example, chromosomes during G1 do not have sister chromatids.

Diana jones is 5'4" and weighs 145 pounds. would the anesthetic choices be the same for diana as they would be for a 6'3" 210 lb
ankoles [38]

Answer:

Propofol (another name Diprivan) can be used for Diana's surgery. It is a sedative or anesthesia commonly used for children and adults. Studies show that there were no significant differences in dose requirements based on sex or age, except for the too elderly.  The difference in dosing considering different body weights were not statistically significant also.  The same dose is safe

( 0.1-0.15 mg/kg/min IV for 3-5 min) for Diana, the 210 lb man or a 10-year-old girl. However, the dose was higher in patients with bradycardia and hypotension.
