Thats the answer please mark me as brainiest
Answer:
V2 = 17371.43ml
Explanation:
We use Boyles laws
since temperature is constant
P1V1=P2V2
760 x 400 = 17.5 x V2
304000 = 17.5 x V2
V2 = 304000/17.5
V2 = 17371.43ml
Answer:
Primary structure is the correct answer.
Explanation:
- The primary structure is the simple level of protein structure.
- Primary structure is a basic amino acids sequences in a protein.
- In the primary structure, amino acids are attached together by a covalent bond.
- Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
- Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.

Answer:
Option B is correct.
4
Explanation:
We know that an atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example, if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
In given problem we are given with 2 neutrons of helium. We know that the atomic number of He is 2. Thus Mass number of He is,
Number of neutrons + number of proton
2 + 2 = 4
Thus, option B is correct.
