Answer:

<em>The correct option is A) controls the movement of substances into and out of cells</em>

Explanation:

As the description tells that the structure is a phospholipid bilayer, one can easily predict that the structure is a plasma membrane. A plasma membrane consists of lipid tail and phosphorus heads. As lipids are hydrophobic they are embedded inwards between the phosphate heads. The plasma membrane also consists of proteins and carbohydrates embedded in its structure. The proteins also facilitate the movement of molecules inside the cell.

The function of the plasma membrane is to allow and control the movement of molecules inside and outside of a cell.

What is happening to the temperature of the substance BEFORE AND AFTER the phase changes?
Neporo4naja [7]
First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.

Calculate the mass, in grams, of the solvent present in a 32.2% solution that contains 14.7 g of NaBr.
emmasim [6.3K]

Answer:

32g

Explanation:

We have to remember that for percent (w/w) concentration we usually write;

Percent concentration= mass of solute/mass of solution ×100

Since mass of solute= 14.7 g and percent concentration = 32.2%

Then

Mass of solution= mass of solute × 100/ percent concentration

Mass of solution= 14.7 ×100/32.2

Mass of solution= 46.7 g

Since mass of solution = mass of solute + mass of solvent

Mass of solute= 14.7 g

Mass of solution = 46.7g

Mass of solvent = 46.7g -14.7g = 32g

An element's atoms are exactly the same - no matter where that element is found.
antoniya [11.8K]

Answer:

B. False

Explanation:

All the atoms of an element are not entirely the same no matter where they are found.

The phenomenon of isotopy brings a different perspective to the identity of an element.

  • Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
  • Isotopes of an element have the same electrons but differ in their masses.
  • They also differ in their chemical properties.
