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.

Question 7: What might be some implications of Robert Hazen’s experiments
Angelina_Jolie [31]

Answer:

Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020) .

Explanation:

Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.

You can read these articles that are certainly clarifying in the description of his experiments and discoveries:

It´s a type of reproduction practiced by Achaea and bacteria which are single-celled organisms.
