Answer:
The answer is
<h2>0.35 g</h2>
Explanation:
The mass of a substance given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 0.253 mL
density = 1.38 g/mL
Substitute the values into the above formula and solve for the mass
We have
mass = 1.38 × 0.253 = 0.34914
We have the final answer as
<h3>0.35 g</h3>
Hope this helps you
Answer:
Denaturation causes loss of enzyme activity which is necessary for biochemical reaction.
Hence many biological process(respiration,digestion,excretion) won't work properly.
Explanation:
Enzymes : These are biological catalyst made of proteins.E.g Pepsin, tyrosine (human digestion)
Denaturation: loss of Quaternary ,tertiary and secondary structure of proteins and nucleic acid because of extreme conditions of temperature , pressure ,pH etc.
When denaturation occur enzymes loss their specific structure, so they can't carry out various life process (e.g respiration, digestion ,excretion).
Enzymes are involved in all biological reaction and work only at optimum temperature ,pH and pressure(human body condition ).

Answer:
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
