Answers

Alpha wavesA healthy adult at rest is most likely to show an EEG pattern characterized by a high level of alpha waves.

Alpha waves are types of brain waves detected by using medical equipment such as magnetoencephalography (MEG) or electroencephalography (EEG), which measures the oscillation of electrical impulses in various sections on the scalp. Alpha waves usually come from the occipital lobe when the eyes are closed during wakeful relaxation such as when performing aerobic exercise. Alpha waves are minimized when sleeping or when the eyes are opened.

What is the growth rate? births = 20 deaths = 10 immigration = 5 emigration = 1 25 20 16 14

Answers

Okay let me settle this now... I, just as most of you, hate the giant long explanations, most people are here for the answer, so I'll do us all a favor here... It's 14.

We will write words shortly for the growth rate GR birth B,for death D,for immigration I and for emigration E.
So N=20
D=10
GR1=?
GR1=N-D
GR1=20-10
GR1=10
AND THEN FORM IMIGRATION AND EMIGRATION.
E=125 20 16 14
I=5
GR=?
GR2=E-I
GR2=125 20 16 14-5
GR2=125 20 16 9
AND THEN
GR2-GR1=GR
GR=125 20 16 9-10
GR=125 20 15
I THINK THIS IS THE ANSWER!!!

Which of the following accurately describes the pH scale? A. The lower the pH is, the more basic the solution is.
B. The lower the concentration of hydrogen ions, the higher the acidity is.
C. The greater the concentration of hydroxide ions, the higher the acidity is.
D. The greater the pH is, the lower the acidity is.

Answers

Well if you haven't found the answer yet it's D, as the pH scale goes from 0-14 where 14 is the most alkaline and 0 is the most acidic. Therefore as you go up the scale, the substance becomes less acidic.

Final answer:

The pH scale measures the acidity or basicity of a solution. The higher the pH, the lower the acidity and the lower the pH, the higher the acidity. It is based on hydrogen ion concentration.

Explanation:

The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It ranges from 0 to 14. A solution with a pH less than 7 is acidic, one with a pH of 7 is neutral, and one with a pH greater than 7 is basic. Therefore, option D is the correct answer. The greater the pH is, the lower the acidity is. The lower the pH, the higher the acidity, and vice versa. This scale is based on the concentration of hydrogen ions (H+) and hydroxide ions (OH-).
