Based on the half-life of carbon-14 atoms, the age of the bone remains is 17100 years.

<h3>What is the age of the bone remains?</h3>

The half-life of carbon-14 is 5700 years

Initially, there are 100% carbon-14 molecules.

After one half-life, there will be 50% carbon-14 atoms.

After two half-lives, there will be 25% carbon-14 atoms.

After three half-lives, there will be 12.5% carbon-14 atoms.

Age of bone remains = 3 half-lives

Age of bone remains = 3 × 5700

Age of bone remains = 17100 years.

Therefore, the age of the bone remains is 17100 years.

If I wanted to test whole milk using all of the indicators (biuret, benedicts, iodine and brown paper bag), what results would y
stellarik [79]

Whole milk will give a biuret positive, Benedict positive, iodine negative and brown paper bag test positive results.

<h3><u>Explanation:</u></h3>

Whole milk is obtained from mainly the dairy animals like cow, Buffalo etc. It contains different ingredients of diet and is considered as an ideal balanced diet for infants.

The Benedict's test is a test to identify the presence of reducing sugars. Milk contains reducing sugar lactose. This is why milk gives Benedict's positive result.

Biuret test also gives positive result because it is a test for protein and milk contains enough of this. The protein in milk is called casein.

The brown paper bag test is a test for lipid and its positive because the milk contains enough lipid. It depends on milk source.

The iodine test is a test for starch and milk isn't a good source of starch. So iodine test isn't positive.

What stage of cellular respiration uses the high-energy electrons from NADH and FADH 2to form ATP molecules?
Romashka [77]
Answer: Oxidative Phosphorylation

-------

Oxidative phosphorylation is the last step of aerobic cellular respiration and is when most of the ATP is created. The electrons from NADH and FADH2 power the proton pumps, which transfer H+ into the matrix that power ATP synthase to make ATP.
