Explain why cuboidal cells would not work as well as squamous cells in the alveoli of the lungs

The surfactant is produced by great alveolar cells (granular pneumonocytes, a cuboidal epithelia), which are the most numerous cells in the alveoli, yet do not cover as much surface area as the squamous alveolar cells (a squamous epithelium<span>).

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

Cuboidal cells are thicker than squamous cells. Cuboidal cells are usually where a function of absorption or secretion is need.

Squamous cells are usually laid in a single layer making the layer thin. This is useful because this type of arrangement allows for diffusion to happen and its used where diffusion is the main type of transport. Remember that the rate of diffusion slows down with distance. In the lungs gas exchange needs to happen very fast to keep a constant supply of oxygen to the lungs. Cuboidal cells would be too thick.

Answer:

Bone marrow.

Explanation:

Hematopiesis may be defined as the formation of the blood cells by the precursor stem cells. This process occurs in the bone marrow, thymus and liver.

The red blood cells are enucleated cells with the minimum span of around 120 days. These cells are processed and destroyed in the spleen. The iron is recovered from the red blood cells and sent again into the bone marrow for the production of new blood cells.

Thus, the answer is bone marrow.

PLEASE HELPPPPP I WILL GIVE BRAINLIEST
Nostrana [21]

Answer:

The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.

Explanation:

It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.

The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.

Form a hypothesis about the relationship between vegetable mass and salinity of the solution
mihalych1998 [28]

Answer:

HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.

Explanation:

Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.

In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:

IF the salinity of the solution decreases, THEN the vegetable mass increases.
