vfiekz [6]2 years ago
7 0

After 2 half-lives there will be 25% (1/4th) of the original isotope, and 75% (3/4 th) of the decay product

<h3>What is Half life period ?</h3>

A half life is a measurement of the slope of an exponential decay function.

It is also defined as, the time it takes to halve the concentration of something in a process.

Each half life you will have half of what you had at the beginning of a given half life.

How do high levels of alkaline phosphatase indicate a bone abnormality
ELEN [110]

Answer:

Bones make an isoenzyme called alkaline phosphatase-2 or (ALP-2). Levels of this enzyme increase when bones are growing or bone cells are active. An alkaline phosphatase bone isoenzyme test can indicate abnormal levels of bone growth that may be associated with conditions such as: Paget's disease of bone.

Explanation:

ALP (alkaline phosphatase) is an enzyme found in your bloodstream. It helps break down proteins in the body and exists in different forms, depending on where it originates.

The bones and liver are the main sources of ALP, but some is also made in your bones, intestines, pancreas, and kidneys. In pregnant women, ALP is made in the placenta.

The ALP test can be helpful in the diagnosis of bone problems such as: rickets, a weakening or softening of the bones in children that’s most commonly due to a significant deficiency of vitamin D or calcium osteomalacia, a softening of the bones in adults usually due to significant vitamin D deficiency, but also possibly due to the body’s inability to process and use vitamin D properly.

Paget’s disease of the bone, a disorder causing major problems with bone destruction and regrowth

An alkaline phosphatase level test (ALP test) measures the amount of alkaline phosphatase enzyme in your bloodstream. The test requires a simple blood draw and is often a routine part of other blood tests.

Abnormal levels of ALP in the blood most often indicate a problem with your liver, gallbladder, or bones. However, they may also indicate malnutrition, kidney cancer tumors, intestinal issues, a pancreas problem, or a serious infection.

The normal range of ALP varies from person to person and depends on ones age, blood type, gender, and pregnancy.

The normal range for serum ALP level is 20 to 140 IU/L.

The normal range runs higher in children and decreases with age.

A sample of chlorine gas occupies a volume of 707 ml at 2.90 atm. What is the new pressure in torr if the volume is compressed t
dolphi86 [110]

Answer:

The new pressure is 3850 torr.  

Explanation:

The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

P_1V_1=P_2V_2

Here,

P_1=2.9\ atm

V_1=707\ mL

V_2=0.533\ L

Let P_2 is the new pressure. So using Boyle's law we get :

P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{2.9\times 707}{0.533}\\\\P_2=3846.71\ \text{torr}

or

P_2=3850\ \text{torr}

So, the new pressure is 3850 torr.
