Answer:
Explanation:
Mendel four postulate is Principles of Paired Factors, Principle of Dominance, Law of Segregation which is Mendels First Law of Inheritance and Law of Independent Assortment which is Mendel’s Second Law of Inheritance.
The six possible outcome are,
3. Alleles segregate from each other during gamete formation at anaphase I gene assorts independent of each other during gametes formation.
4. Some genes have dominant and recessive alleles. Allele of a gene can either be dominant or recessive in its form
7. Unit factors occur in pairs , allele of a gene occur in pair
Dominant alleles can become codominant alleles during mitosis, when two allele both finds expression in the phenotype of an organism they are codominant
8. One gene pair separates independently from other gene pairs independent assessment of gene.
5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
Answer:
respiratory system
Explanation:
The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.
WHAT IS TONICITY?
- Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic
- A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.
- If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.
Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.
