An exchange reaction occurs between compounds that, when written as a molecular equation, appear to involve the exchange of parts between the two reactants. An exchange reaction will occur when ions in solution form insoluble products, weak electrolytes, or non electrolytes.
Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
Bacteria and archaea are the two types of living beings made up of prokaryotic cells.
<h3>What are bacteria and archaea?</h3>
Bacteria and archaea are both prokaryotic and unicellular organisms. This means that they both lack a true nucleus and membrane-bound organelles. The genetic material is present in a long single loop of chromosome, called the nucleoid.
Both bacteria and archaea have a cell wall present outside of the cell membrane. The structural composition of the cell wall is different among them. In bacteria, the cell wall is made up of peptidoglycan (a sugar and protein complex compound) and in archaea, it is made of pure polysaccharides.
Both of these organisms reproduce asexually. They also have flagella for locomotion, pilus for adherence and a capsule outside of the cell wall for protection against conditions like dehydration.
Therefore, bacteria and archaea are living beings made up of prokaryotic cells.

Answer:
energy changes from one form to another
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
- Non- reciprocal translocation
A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.
Hope this helps...
