Answer:

The cell will shrink due to osmosis.

Explanation:

As in given question the salt concentration are much more inside the cell, than outside. In order to maintain equilibrium. the water inside the cell will start flowing outside in order to maintain equilibrium, causing shrinkage of cell. The ability of a cell to divide or function will reduce because of water loss. This phenomenon is seen in case of hypertonic solution. Water will start diffusing from the higher concentration to the lower concentration.

How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?

vaieri [72.5K]

Explanation:

The given data is as follows.

$M_{1}$ = 3 M, $V_{1}$ = ?

$M_{2}$ = 10 M, $V_{2}$ = 10.0 ml

Therefore, calculate the volume of given solution as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

Now, putting the given values into the above formula as follows.

$M_{1} \times V_{1}$ = $M_{2} \times V_{2}$

$3 M \times V_{1}$ = $10 M \times 10.0 ml$

$V_{1}$ = 33.3 ml

or, = 0.033 L (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

Molarity = $\frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}$

3 M = $\frac{mass}{40 g/mol \times 0.033 L}$

mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

What kind of tissue provides plants with the first line of defense against damage and disease?

sergeinik [125]

The best answer - dermal tissue.

Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.

Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.

Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.
