1. Answer:

B) An allele is one form of a gene.

Explanation:

  • <em><u>An allele refers to an alternative form of a gene. In other words it is one of the form of a gene.</u></em>
  • <em><u>A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele. </u></em>
  • A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.
  • A heterozygous organisms contain one dominant allele and one recessive allele.

2. Answer;

B) Alleles

Explanation;

  • <em><u>According to Mendel genes are inherited in pairs of alleles that behave in a dominant and recessive pattern. </u></em>
  • <em><u>Alleles are alternative forms of a gene. </u></em>
  • A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele.
  • A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.

Enumerate any two differences between simple distillation and fractional distillation.
mr_godi [17]

Answer:

Explanation:

By simple distillation, we can separate tow miscible liquids having sufficient difference in their boiling points.

By fractional distillation, we can separate the mixture of two or more miscible liquids for which the difference in their boiling point is less than 25k

Simple distillation is done using an air condenser or water condenser.

Fractionating column is fitted in between the distillation flask and the condenser for the process.

Simple distillation eg: mixture of water and acetone

fractional distillation eg: crude oil

hope this helps

A balloon containing N2 has 1.70 moles and occupies 3.80L. What will the volume be if the number of moles is increased to 2.60mo
leonid [27]

Answer:

5.81L

Explanation:

N1 = 1.70 moles

V1 = 3.80L

V2 = ?

N2 = 2.60 moles

Mole - volume relationship,

N1 / V1 = N2 / V2

V2 = (N2 × V1) / N1

V2 = (2.60 × 3.80) / 1.70

V2 = 9.88 / 1.70

V2 = 5.81 L

The volume of the gas is 5.81L

What is the composition, in atom percent, of an alloy that consists of 30 wt% Zn and 70 wt% Cu?
Xelga [282]

The composition, in atom percent, of an alloy that consists of 30 wt% Zn and 70 wt% Cu is 29.4 at % and 70.6 at % for Zn and Cu respectively.

<h3>How to convert weight % to atom %?</h3>

The weight percentage of an element can be converted to atom percentage as follows:

  1. C(Zn) = C1A2 / (C2A1) + (C1A2) × 100
  2. C(Cu) = C2A1 / (C1A2) + (C2A1) × 100

Where;

  • C1 = 30
  • C2 = 70
  • A1 = 65.4g/mol
  • A2 = 63.55g/mol

  • C(Zn) = {30*63.55} / (70*65.4) + (30*63.55) × 100
  • C(Cu) = {70*65.4} / (30*63.55) + (70*65.4) × 100

  • C(Zn) = 29.4 at %
  • C(Cu) = 70.6 at %

Therefore, the composition, in atom percent, of an alloy that consists of 30 wt% Zn and 70 wt% Cu is 29.4 at % and 70.6 at % for Zn and Cu respectively.
