The allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.
X-linked recessive inheritanceFemales usually inherit two chromosomes X, while men inherit only one chromosome X (and one chromosome Y).
The inheritance of the chromosome X in females resembles mendelian inheritance because females have two X chromosomes.In this case, females having the genotype XRXr are carriers because lowercase letters denote the presence of the recessive allele.In conclusion, the allele combination XRXr represents a female who is a carrier for an X-linked recessive disorder.

How are meiosis and mitosis different?
Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Explanation:
:)
Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

Which of these statements about ocean water is always correct?
a.) Its area is less than the area of freshwater.
b.)Its salinity is less than the salinity of freshwater.
c.) Its density is greater than the density of freshwater.
d.)Its temperature is greater than the temperature of freshwater.
Answer:
c.) Its density is greater than the density of freshwater.Explanation:
Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.
The freezing point of seawater decreases as salt concentration increases.
Answer:
C.) Its density is greater than the density of freshwater.
Explanation:
Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

explain the term.evapouration
Answer:
the process of turning from liquid into vapour
Answer:
Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).

What is the relationship between the temperature of internal material and volcanic eruptions?
plz help.....
Answer:
Direct relationship.
Explanation:
There is direct relationship between the temperature of internal material and volcanic eruptions because the temperature of internal material causes the volcanic eruptions. The temperature of the internal material puts pressure on the rocky surface and the gases that releases from heating processes will cause pressure which leads to the eruption of the volcano so we can say that there is a direct relationship between temperature and eruption.
