Kay [80]

fibrous roots; taproots

Explanation:

A taproot root consists of one large main root with smaller roots that branches off into the soil, while the fibrous roots consists of several main roots that branches off to form one mass of roots.

The root system in plants helps them to absorb water and other nutrients from the soil.
A taproot is much more like extension of stem that penetrates into the ground.
It tapers at the end with many other smaller roots branching and networking from it.
The fibrous root is a series of roots directly from the stem that independent of one another.
Roots are used by plants for anchorage into the soil.

Chloroform is a liquid once used for anesthetic. What is the volume of 5.0 g of chloroform? The density of chloroform 1.49 g/mL

mario62 [17]

Answer:

3.3557047 mL

Explanation:

The density can be found using the following formula:

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

Let's rearrange the formula to find the volume, $v$ .

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

$d*v=m$

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

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

The volume can be found by dividing the mass by the density. The mass of the chloroform is 5 grams and the density is 1.49 grams per milliliter. Therefore,

$m= 5g \\d= 1.49 g/mL$
