Answer:
First off Life sciences are anything concerned with the study of a living organisms. So ones that would be included would be, microbiology biology, botany, zoology, ecology, genetics and medicine, from what the dictionary states
Explanation:
Biology is the natural science that studies life and living organisms. Which also includes molecular interactions, including their physical structure.
Genetics, is the study of heredity and or the variation of inherited characteristics that we get from family.
Microbiology, is the branch of science which deals with microorganisms.
Let me know if this helps, if not I'll continue researching.
... in neutralization reactions, for example:
NaOH + HCl = NaCl + H₂O
2KOH + H₂SO₄ = K₂SO₄ + 2H₂O
All of the above I think it might not be right
Answer:
A. 28 years
Explanation:
Applying,
R = R'(2ᵃ/ⁿ).............. Equation 1
Where R = Original sample, R' = Sample left after decay, a = Total time taken to decay, n = half life.
From the question,
Given: R = 12 g, R' = 6 g, a = 28 years.
Substitute into equation 1 and solve for n
12 = 6(2²⁸/ⁿ)
12/6 = 2²⁸/ⁿ
2²⁸/ⁿ = 2
Equation the base,
28/n = 1
n = 28 years.
Hence the half-life is 28 years
Atoms are (stable) if it has (valence) electrons in its outer most energy level.
