Answer:
The answer to your question is the original dose of Ba-142 was 1184 μg
Explanation:
Data
Total time = 1.25 hours
The Final amount of Ba = 9.25 μg
The Half-life of Ba = 10.6 minutes
Process
1.- Convert total time to minutes
1 h ----------------- 60 min
1.25 h ------------ x
x = 75 min
2.- Draw a table of this process
Final amount of Ba Time
9.25 75 min
18.5 64.4 min
37 53.8 min
74 43.2 min
148 32.6 min
296 22 min
592 11.4 min
1184 0.8 min
Answer:

<span>Hello!
The statement that best proves that the law of conservation is obeyed during this process is that </span><span>The total mass of oxygen and carbon is equal to the total mass of carbon dioxide.
The chemical equation for the combustion reaction of coal in the carbon cycle is the following one:
C(s) + O</span>₂(g) → CO₂(g)
<span>
From this simple chemical equation, we can conclude that if the Law of Conservation of Matter is obeyed in this reaction, the sum of the initial masses of Carbon and Oxygen before the reaction will be equal to the total amount of Carbon Dioxide formed by it, because they sum up to produce Carbon Dioxide.
Have a nice day!</span>
Answer: Tides are the regular, alternating rise and fall of sea level caused by the gravitational pull of the moon and sun. The changing of the tide is often rapid and dramatic. On a smaller scale, similar motions occur on large lakes, in the atmosphere, and even within the solid earth.
Explanation: can I please have brainliest?
Answer:
<em>D) raises blood glucose levels. </em>
Explanation:
Glucagon is a small polypeptide synthesized by cells. This 29 amino acid peptide hormone is synthesized by pancreas alpha cells and has a molecular weight of 3485 dalton
It has an opposite effect to insulin by increasing blood glucose levels since it increases phosphorylase activity through cyclic AMP, after binding to glucagon receptors coupled to protein G on hepatocytes.
It is a stress hormone. Stimulates catabolic processes and inhibits anabolic processes.
The correct answer is D. raises blood glucose levels.
