Answer:
Explanation:
Alleles are the pairs of genes occupying a specific spot on a chromosome. That spot is called locus. For example, a pair of alleles controlling the same trait, i.e. eye color: one allele codes for blue eyes, another allele for brown eyes.

I would suggest the answer D: A paint manufacturer
Answer:
- 0.0413°C ≅ - 0.041°C (nearest thousands).
Explanation:
- Adding solute to water causes the depression of the freezing point.
<em>ΔTf = Kf.m,</em>
Where,
ΔTf is the change in the freezing point.
Kf is the freezing point depression constant (Kf = 1.86 °C/m).
m is the molality of the solution.
<em>Molality is the no. of moles of solute per kg of the solution.</em>
- <em>no. of moles of solute (glucose) = mass/molar mass</em> = (8.44 g)/(180.156 g/mol) = <em>0.04685 mol.</em>
<em>∴ molality (m) = no. of moles of solute/kg of solvent</em> = (0.04685 mol)/(2.11 kg) = <em>0.0222 m.</em>
∴ ΔTf = Kf.m = (1.86 °C/m)(0.0222 m) = 0.0413°C.
<em>∴ The freezing point of the solution = the freezing point of water - ΔTf </em>= 0.0°C - 0.0413°C = <em>- 0.0413°C ≅ - 0.041°C (nearest thousands).</em>

Answer:
Evaporation wll occur
Explanation:
Boiling point is reached when the vapor pressure equals the atmospheric pressure around. The vapor pressure is the pressure exerted by a gas which is in contact with its own solution or liquid. It increases with increasing temperature.
The atmospheric pressure is the pressure of the atmosphere around. When the vapor pressure exceeds atmospheric pressure, boiling point is reached and surpassed. At this point, evaporation will occur.
