Selectively permeable (or semi permeable) means where for example a membrane can choose what material can pass through while others cannot. They control the in and out of materials.
This is because the membrane has tiny spaces, where only smaller molecules can pass through, other larger ones cannot.

Answer:

"This is the reason you are using a special swallowing technique when you eat and drink."

Explanation:

Based on the information provided within the question it can be said that the most appropriate statement by the nurse would be "This is the reason you are using a special swallowing technique when you eat and drink."

Na + Cl2 --> NaCl if you were given 15 grams of sodium (with excess chlorine) and asked to determine the amount of NaCl that
Elena-2011 [213]

Answer:

The correct answer is - 38.15 gm of NaCl.

Explanation:

Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):

2Na + Cl₂ —> 2NaCl

the mass of Na and the mass of NaCl :

Molar mass of Na = 23 g/mol

In the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

similarly in balanced equation = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

By converting it to 15 grams of Na.

Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.

Thus, 38.15 g of Na

Which of the following events characterizes metaphase of mitosis?
Natalka [10]

A.chromosomes aligning themselves at the equator.

<h3>What distinguishing features of mitosis' metaphase?</h3>

A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.

<h3>What distinguishes metaphase from other phases?</h3>

Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.

<span>a).only leaves will show color flower will tend to be dark. b).only flower will show up leaves will tend to be dark. c). both leaves and flowers will be dark. (any object which has a color absorbs rest of colors of spectrum except that color which it reflects for example: green leaves absorbed v.i.b.y.o.r. except green which is reflected by leaves) so if placed in red light they will not show any color because leaves will absorb red color)</span>
