Sedimentary rock forms *over time,* which means that those rocks had to form over millions of years, proving that the Earth has been forming and changing all this time.
Hypoproteinemia is a condition of unusually low levels of plasma proteins. The problem is usually characterized by tissue edema.
What is edema?
Edema is the build up of fluid in the body's tissue. It occurs when tiny blood vessels in our body (capillaries) leak fluid. The fluid builds up in surrounding tissues, leading to swelling. Edema can affect anyone, but the condition most often affects people who are pregnant and adults who are 65 years or older.
There are four types of edema:
- Peripheral edema: This affects the feet, ankles, legs, hands, and arms.
- Pulmonary edema: This occurs when excess fluid collects in the lungs, making breathing difficult.
- Cerebral edema: This occurs in the brain.
- Macular edema: This is a serious complication of diabetic retinopathy.

After the 1st half-life 250 g of the radioactive material will be left.
<span>After the 2nd half-life 125 g of the radioactive material will be left. </span>
<span>After the 3rd half-life 62.5 g of the radioactive material will be left. </span>
<span>Therefore after 60 minutes, 3 half lives would have occurred. </span>
<span>Therefore the half-life = 60 / 3 = 20 minutes when 250 grams of the original material would have remained radioactive. </span>
<span>Therefore the answer is A) About 250 gram of the material decayed in 20 minutes.</span>
You have to remember that a scientific hypothesis is a question about whether or not something will happen the way you think it will.
