<h2>Mitosis Process</h2>

Explanation:

Plant cells and animal cells undergo the same cellular processes during mitosis.

The centrioles absent in the plant.
Animals cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
<em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each new nuclei.</em>

Someone please help me with this :,,,,,,,,,,,)

tamaranim1 [39]

Answer:

1. 1.26823082 mL

2. 0.5 g/mL

Explanation:

The density formula is: $d=\frac{m}{v}$

1.

Rearrange the density formula for v,

$d=\frac{m}{v}$

$d*v=\frac{m}{v}*v$ <em>Multiply both sides by v.</em>

$d*v=m$

$\frac{d*v}{d} =\frac{m}{d}$ <em>Divide both sides by d.</em>

$v=\frac{m}{d}$

Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.

$m= 20 \ g\\d= 15.77 \ g/mL$

Substitute the values into the formula.

$v=\frac{20 \ g} {15.77 \ g/mL}$

Divide. Note the grams, g, will cancel.

$v= 1.26823082 \ mL$

2.

Use the density formula.

$d=\frac{m}{v}$

Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.

$m= 10 \ g\\v= 20 \ mL$

Substitute the values into the formula.

$d=\frac{10 \ g}{ 20 \ mL}$

Divide.

$d= \frac{1}{2} \ g/mL$

$d= 0.5 \ g/mL$
