Which factor below would be least likely to cause a mutation in the cells of an organism. Select one: a. Radiation b. Smoking c.
Nutka1998 [239]

Answer:

The correct option is;

c. Sound wave

Explanation:

The given options effect on mutation are given as follows;

a. Radiation

Radiation such as ultraviolet light and gamma radiation, which are electromagnetic waves, cause mutations by causing the formation of free radicals within an organism's cell resulting in the mutation characteristic effects

b. Smoking of tobacco has mutagenic effects due to the presence of several carcinogenic compounds in cigarettes

c. Sound wave is a form of mechanical wave and has no chemical effects on the chemistry of an organism and therefore does not cause mutation in cells

d. Chemical pollution can contain carcinogenic compounds that can cause mutations in the cells of organisms.

What mass of caco3 (in grams) is needed to make 10.5 l of a 1.50 m caco3 solution?
kiruha [24]
Data:

M = 1.50 (assiming the data is Molarity and not molality, which is written with capital letter)

V= 10.5 l

n = ?

Formulas:

M = n / V => n = M * V

n = mass in grams / molar mass => mass in grams = n * molar mass

Solution

n = 1.50 * 10. 5 l = 15.75 moles

molar mass CaCO3 = 40.08 g/mol + 12.01 g/mol + 3* 16 g/mol = 100.09 g/mol

mass in grams = 15.75 moles * 100.09 g/mol = 1,576.4 g.

Answer: 1,576 g

BOTH acids and bases
aalyn [17]

D) conduct electricity in water.

Explanation:

Both acids and bases conducts electricity in water.

When acid dissolves in water, they are good electrolytes.

When bases dissolves in water they are good electrolytes.

  • Electrolytes are liquid or molten substances that are able to conduct electricity.
  • they conduct electricity by the use of their ions in solution.
  • Since acid and bases ionize in solution, they will conduct electricity.

An acid is a substance that produces excess hydroxonium ion in solution.

A base produces excess hydroxyl ions in solution
