Answer:

Explanation:

Air pollutants also affect the biosphere in turn. Ozone and acid deposition suppress plant growth; meanwhile, aerosols and their indirect effects on clouds decrease total photosynthetically active radiation (PAR) while increasing the diffuse fraction.

Using Dimensional Analysis
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

4.00 g S

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of S - 32.07 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 4.00 \ g \ S(\frac{1 \ mol \ S}{32.07 \ g \ S})(\frac{6.022 \cdot 10^{23} \ atoms \ S}{1 \ mol \ S})$
Multiply: $\displaystyle 7.51107 \cdot 10^{22} \ atoms \ S$

<u>Step 4: Check</u>

<em>Follow sig figs and round. We are given 3 sig figs.</em>

7.51107 × 10²² atoms S ≈ 7.51 × 10²² atoms S

If a body does not have enough potassium, how might that affect neuronal firing?

astraxan [27]

Potassium is fundamental for neuron activity. If a body does not have enough potassium, then the neuron will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.

The potassium (K+) is maintained at a high level within the neuron at rest, whereas sodium (Na+) is maintained at a high level outside of the cell.

Neurons contain K+ and Na+ leakage channels that allow the two ions to diffuse in favor of a concentration gradient.

Depolarization opens both K+ and Na+ channels in the membrane, thereby these ions can flow out and into the axon, respectively.
