Two molecules are formed

Two molecules are formed, each with one original side.
This is because the starting DNA molecule undergoing mitosis splits in half and the other half is completed by free nucleotides using the enzyme Polymerase.

How many new volumes would each new cell contain whenever a cell splits?
Elenna [48]
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.

In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-posi
asambeis [7]

Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.  

Answer: Option B & C

<u>Explanation:</u>

Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.

On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.

Vagal stimulation during suctioning can contribute to which conditions? select all that apply.
Fynjy0 [20]

Answer;

-Bradycardia

-Heart block

-Asystole

Explanation;

-Tracheal suctioning can cause a vagal response. This stimulus influences the electrical system of the heart, potentially leading to decreased heart rate (bradycardia), heart block, asystole, or other dysrhythmias.

-Bronchospasm would not be induced by this type of stimulus. Vagal stimulation can result in hypotension, not hypertension.
