Electrons are located outside of the nucleus.

Unlike their partners; protons and neutrons, who are located inside the nucleus, electrons are only found outside the nucleus.

I hope this helps!

Do you think that the soles of of your feet or the back of your neck has the greater concentration of sensory receptors

mars1129 [50]

The soles of people’s feet have a greater concentration of sensory receptors because more people are ticklish on the bottoms of their feet than the backs of their necks. There are more neurons in your appendages especially the ends of them because they are the furthest from the brain. Getting a tattoo on your feet vs. the back of your neck hurts more as well, making the soles of your feet have the greater concentration.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?

Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= $\frac{600}{20}$ = 30

for a pH 2= [H+]= $10^{=2}$

∴ [H+]= $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

and pH is an antilog of [H+]= - log $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

∴pH = 3.47

D- both involve moving substances across a membrane
Reasoning:
-Active transport moves against the concentration gradient ( low to high)
-Passive transport moves higher to lower concentration
