Answer:
Secondary structure
The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom
Answer:
freezing point and melting point
Answer:
The approximate number of decays this represent is
Explanation:
From the question we are told that
The amount of Radiation received by an average american is 
The source of the radiation is 
Generally

Therefore 
Also 
Therefore 
An Average american weighs 88.7 kg
The total energy received is mathematically evaluated as

Cross-multiplying and making x the subject


Therefore the total energy deposited is 
The approximate number of decays this represent is mathematically evaluated as
N = 
Where n is the approximate number of decay
Substituting values
Answer:
972 J
Explanation:
At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:
GPE = mass×gravity×heigth
GPE = 2.2×9.8×45.08 ≈ 972
Answer:
this is because the light rays get reflected irregularly
Explanation:
