Answer:

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"

Explanation:

All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.

One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.

Yanka [14]

Answer:

Osteoblast, osteocytes and osteoclasts  are responsible for breaking down bone during remodeling.

Explanation:

The process which is responsible during bone formation in equally in initial and later stages of remodelling, they are the bigger cells which are responsible for the synthesis and mineralisation  of bone. Osteocytes are the rich in cells in the bone tissue, which is helpful in detection of the mechanical loading, also manages the in bone formation and bone resorption. Osteoclast are cells that disintegrate the bone to start normal bone remodelling and also contemplate bone loss in pathologic condition by growing its resorptive capacity.

You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. You do a little research on the In
Licemer1 [7]

Answer:

<em>C: After 1 hour, the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3</em>

Explanation:

The degree of acidity or alkalinity/basicity of a substance is its pH. The value of pH ranges from 1 to 14 with the former being extreme acidity and the latter being extreme alkalinity while pH 7 is considered neutral.

Hence, any pH below 7 is considered acidic and above 7 is considered alkaline.

Reactions involving equal volumes of an acid and a base can end in acidic, alkaline or neutral pH depending on the strength of the acid/base involved;

  • Equal volumes of strong acid with strong base will result in neutral pH
  • Equal volumes of weak acid with strong base will result in alkaline pH
  • Equal volume of strong acid with weak base will result in acidic pH

If substance A and B reacts with equal volume of the same acid under the same condition and the end result of A is a solution with pH of 9.2 and that of B is a pH of 8.3, it simply means substance A is a stronger base than substance B.

<em>Hence, the only outcome that supports the hypothesis that a tablet of PEPCID AC can neutralize more stomach acid than a tablet of Alka-Seltzer is that the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3 after being subjected to the same condition.</em>

If an indigestion is due to excess stomach acid, the only way to reduce the acidity is to consume a substance that will decrease the degree of acidity in the stomach. This means that the patient will need to consume something that is alkaline in order to increase the pH.
