I think it is B I had done these.
Answer:
The correct answer is 1 RNA Polymerase
Explanation:
RNA polymerase helps in the formation of RNA from DNA by the process known as transcription.There are 3 types of RNA Polymerase in Eukaryotic cell they are given below
1 RNA Polymerase 1 this enzyme helps in the synthesis of ribosomal RNA or rRNA.
2 RNA Polymerase 2 this enzyme helps in the formation of messenger RNA or mRNA .
3 RNA Polymerase 3 this enzyme helps in the synthesis of transfer RNA or tRNA.
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.
