Answer:
0.00568
Explanation:
Recall that the fraction of radioactive material left after a time (t) is obtained from the formula;
N/No = (1/2)^t/t1/2
Where;
N= mass of radioactive material left after a time t
No= mass of radioactive material initially present
t= time taken for N mass of radioactive substance to remain = 60.0 days
t1/2= half-life of the radioactive substance= 8.04 days
Note that the required fraction is N/No, hence;
N/No= (1/2)^60.0/8.04
N/No= (1/2)^7.46
N/No = 0.00568

Hope this helps you
oxygen. 99% of your body is composed of oxygen, nitrogen, hydrogen, calcium. 85% of your body is composed with other elements. I hope that helps!!!
Answer:
1. Synthesis and repair of muscle tissue
2. Production of ATP
3. Synthesis of glucose
Explanation:
Proteins are primarily used for tissue repairs and synthesis. They are polymers of amino acids used to make hormones, enzymes and other chemicals of the body. Therefore proteins are only reserved for synthesis and repairs of tissues.
During extreme starvation periods when then is no source of carbohydrates and adipose tissues has been depleted/used up, proteins are alternatively used as source of energy in form of amino acids that enters the liver. Tissues such as muscles are protein degraded to provide the brain with energy in form of ketone bodies and glucose, thus the weight loss in people suffering from malnutrition.

oxygen
Your cells need oxygen to convert the nutrients you eat into energy for your body. In the process of making that energy, some waste products are produced. One of the main waste products is a gas called carbon dioxide.
