Answer:

The respiratory epithelium is a type of ciliated pseudostratified columnar epithelium.

Explanation:

The epithelium (a type of tissue) lines the blood vessels and inner-outer surfaces of organs. Their function includes protection, secretion, absorption, transport, etc. Based on the shape, they are classified as squamous, columnar, and cuboidal. Also, they can be simple epithelium (a single layer of cells) or stratified (layers of two or more cells).

Respiratory epithelium (airway epithelium) is a type of ciliated pseudostratified columnar epithelium. It is the epithelium that is found in the respiratory mucosa and lines most of the respiratory tract. It protects and moist the airways. It prevents infection by the self-cleaning mechanism of the airways (mucociliary clearance) and thus acts as a barrier to pathogens and foreign particles. It also secretes mucus and prevents tissue injury. The respiratory epithelium contains four types of cells-ciliated, goblet, club and airway basal cells. The arrangement of these multiple cell types as a single layer results in the non- alignment of their nuclei in the same plane. So the epithelium appears as layered or stratified. Hence the name pseudostratified or falsely layered.

Outline the process of the Carbon Cycle.
Bond [772]

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Why salivary amylase is active in the mouth, but becomes inactive in the stomach?
Cerrena [4.2K]
It becomes inactive in the stomach because of the stomach having a MUCH greater PH level then the mouth. It is typically 1.0-2.0 in the Stomach which is extremely acidic which causes it to change shape and therefore inactive.

Which of the statements about half-life are true?
Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.
