How is the process of mitosis essential to the survival of an organism?
ELEN [110]

Answer:

Explanation:

Mitosis is crucial to this process. Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.Jul 22, 2020

5. What volume of silver metal will weigh exactly 4500.0 g. The density of silver is 20.5 g/cm.
Vitek1552 [10]

Answer:

The answer is

<h2>219.5 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 4500 g

density = 20.5 g/cm³

We have

volume =  \frac{4500 }{20.5}  \\  = 219.51219...

We have the final answer as

<h3>219.51 mL</h3>

Hope this helps you
