They are also called the noble gases or inert gases. They
are virtually unreactive towards other elements or compounds. They are found in
trace amounts in the atmosphere. Their elemental form at room temperature is
colorless, odorless and monatomic gases. They also have full octet of eight
valence electrons in their highest orbitals so they have a very little tendency
to gain or lose electrons to form ions or share electrons with other elements
in covalent bonds.
The answer is (A).
Hope this helps :).
Answer:
correct substrate to bind the active site of the enzyme.
Explanation:
For an enzyme to catalyze a chemical reaction it is very essential for the correct substrate to bind the active site of the enzyme.
The Active site consists of two parts
1.Binding site
2. Catalytic site
The binding site consists of amino acid residues that bind to the correct substrate while the catalytic site has the amino acids that lead to the catalysis.
The active site's shape is such that only the right substratum easily binds to it and thus the catalytic reaction occurs.
To compute for grams of fat in each salad:
We know that, A = C.
And B is 5 grams more, so it is B = 5 + A
And the total fat is 65, so A + B + C = 65 grams.
Computation:
A + (5 + A) + A = 65
3A + 5 = 65
3A = 60
A = 20
A = 20
B = (65 - 40) = 25
C = 20
