tatiyna

Papessa [141]

Answer:

<em>The correct option is C. Mendel's laws of segregation and independent assortment</em>

Explanation:

Mendel's law of segregation states that the two alleles of a gene pair segregate individually at the time of the formation of gametes. They also unite independently during the time of fertilization. We can see that in the scenario mentioned in the question, the alleles segregate independently.

Mendel's law of independent assortment states that the alleles of different genes assort independently at the time of gamete formation. Different traits are passed from the parents to the offsprings irrespective of one another.

max2010maxim [7]

The anterior portions of the nasal cavities just inside the nostrils are known as the Vestibules

<h3>What are nasal vestibules? </h3>
  • The nasal vestibule is the area just inside the nostril (nose opening) that leads into the nasal cavity.
  • The nasal vestibule contains cartilage of the nose and is lined with tissue that contains small, course hair. These hairs help filter dust, sand, and other particles to stay them from entering the lungs.
  • The vestibule of the traditional adult nose is a specialized organ with very characteristic structures and specific functions and is the beginning of each nasal passage. Here the tract makes its first contact with the outside world of air.
  • The vestibule is surrounded almost entirely by its half the nasal lobule, bounded laterally by the ala, or wing, medially by the mobile septum and columella, superiorly by the cul-de-sac and limen vestibuli, and posteriorly by the skin lying on the alveolar ridge of the superior maxilla

which of the following is FALSEA cell will shrink when the concentration of electrolytes is greater inside the cell than outside
uranmaximum [27]

Answer:

A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.

Explanation:

<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>

Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
