What tissues are in the respiratory system?
seropon [69]

Answer:

Simple squamous epithelium,stratified squamous epithelium,pseudostratified columnar epithelium

Explanation:

The respiratory system is made up of many different types of tissues and they differ according to their locations in the respiratory system.

1.Simple squamous epithelium: It is found within the alveoles of the lungs. These cells are single layer,flat (squamous) cells. It controls the permeability of blood vessels in the lungs. When you inhale it allows more oxygen to be absorbed in the  blood flows.

2.stratified squamous epithelium: It is found at mouth surface primarily tongue and throat . These cells are stratified that is they are many layered because everyday whatever we put in our  mouth and throat it protects from wear and tear. It gives physical protection from pathogens as well.

3.pseudostratified columnar epithelium: It is a lining of the nasal cavity trachea and bronchi. This layer is ciliary to trap patheogen on entering into the lungs.

Answer:

Mendel's law of independent assortment

Explanation:

Gregor Mendel is a really important figure in genetics, his work on pea plants provided us with many of the fundamentals of genetics that we still have today!

Mendel proposed 3 laws:

1. The law of dominance - this law states that where there are two different alleles (heterozygous) the organism will always express the dominant trait over the recessive trait

2. The law of segregation - this law states that offspring will inherit one allele from each parent, because allele pairs separate in the process of meiosis, such that each gamete contains 1 allele of each trait. When the zygote is formed, it contains an allele from each parent.

3. The law of independent assortment - this law states that traits are independent from one another at the time of gamete formation. The genes are segregated separately from one another, as the presence of one does not impact the presence of another.

This example shows that all combinations of the height and color allele are possible, and therefore nicely demonstrates the law of independent assortment
