Answer : An atom with 7 protons, 6 neutrons,
and 7 electrons has an atomic mass of 13 amu.
Explanation:
As we are give that,
Number of protons
7
Number of electrons =7
Number of neutrons =6
As we know that,
Atomic number =Number of protons = Number
of electrons =7
Atomic mass = Number of neutrons + Atomic
number
Atomic mass = 6 + 7 = 13 amu
Therefore, the atomic mass is, 13 amu
there are many ways of explaining the characteristics of mineral
1. mineral are natural
2.mineral are inorganic
3. minerals are solid
4. definite chemical composition
5. crystalline structure
Plasma contains albumins that need we need to maintain osmotic balance
The RNA synthesis or ADN transcription occurs in the nucleus and requires:
- DNA strand to act as a template.
- Enzymes, specially the RNA-polymerase.
- Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
