Can someone please help me out?!

Biology
1 answer:
Dmitry [639]3 years ago
6 0

Answer:

1. higher

2. Na + (Sodium)

3. Ca 2+ (Calcium)

4. 30mM

5. 20 mM of sodium (Na 2+) ions left over

6. K+ (Potassium)

Explanation:

1. The graph shows that potassium ions (K+) inside the cells (denoted by the gray bars) are at a concentration of approx 150mM. The concentration outside the cells (the black bars) is approx 10mM. Therefore, the concentration K+ inside the cells is much higher than the concentration outside the cell

2. The concentration of different ions outside the cell are marked by the black bars. The highest concentration of any of the black bars is approximately 130 mM (i.e. the largest black bar), which you can see from the graph is the concentration of sodium ions (Na+) outside the cell.

3. The concentration of different ions inside the cell are marked with gray bars. The lowest concentration of any of the grey bars (i.e. the smallest gray bar) is around 5 mM, which you can see from the graph is the concentration of calcium ions (Ca2+)

4. The concentration of Mg2+ ions inside the cell is represented with the gray bar. Looking at the graph, the gray bar reaches a concentration just over half way between the 0 and 50 mM markers, suggesting the concentration is approximately 30 mM.

5. There is approximately 20 mM Na2+ inside the cell, and 130 mM outside the cell, adding up to 150 mM in total. There is approximately 10mM of sodium ions inside the cell, and approximately 120 mM outside the cell, amounting to 130 mM total. This means there is about 20 mM of sodium (Na 2+) ions left over

6. We can tell by looking that ithe biggest differences between outside and inside the cell is either sodium ions, potassium ions or chlorine ions.

Approximate ion concentrations are listed:

  • Na ions inside = 20 mM, Na ions outside = 130 mM. Diff = 110 mM
  • <u>K ions inside = 150 mM, K ions outside = 10mM. Difference = 140 mM</u>
  • Ca ions inside = 5 mM, Ca ions outside = 10mM. Difference = 5 mM
  • Mg ions inside = 30 mM, Mg ions outisde = 2 mM. Difference = 28 mM
  • HCO3 ions inside = 25 mM, HCO3 ions outside = 15 mM. Diff = 10 mM
  • Cl ions inside = 10 mM, Cl ions outside = 120 mM. Difference = 110 mM

The biggest difference between inside and outside is potassium ions, K+

What is the main prerequisite for clearance at the G2 checkpoint?
Katena32 [7]

Answer:

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.
