Answer:
the answer is D that is literally the most logical one
Answer:
500 m/s
Explanation:
Velocity (v) = wavelength (λ) x frequency (f)
V = 10 x 50
V = 500 m/s
The would have to be weather
The question is incomplete as it does not have the options which are:
- Simple squamous
- Simple columnar
- Pseudostratified squamous
- Stratified squamous
- Stratified columnar
Answer:
Stratified columnar
Explanation:
Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.
In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.
Therefore, the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.
Thus, Stratified columnar is the correct answer.
Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs called alveoli in mammals and reptiles, but atria in birds. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.
