Cell processes that increase the surface area of a cell are called:

Biology
1 answer:
wlad13 [49]3 years ago
4 0

Answer:

Answer below

Explanation:

  • As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly).
  • Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
  • Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration.
  • These foldings too increase the surface area.

Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.

Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.

In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,

Non-motile cilia are structures in a cell membrane that also increase surface area. Non-motile cilia are like oars that push through the cell membrane. They are thinner and longer than microvilli. Non-motile cilia are also called primary cilia.

how does the second law of thermodynamics help explain the diffusion of a substance across a membrane?
Damm [24]

The second law is the trend toward randomization, or increasing entropy.  

Second law allows for diffusion because diffusion is an increase in entropy .Diffusion is the process of movement of molecule down the concentration gradient until they doesn't exist . This movement represents an increase in the entropy.

Second Law of Thermodynamics state that molecules will spontaneously move towards an area of lower concentration, from an area of higher concentration. Molecule are capable to travel across cell membranes known as lipophilic molecules as they dissolve in the lipid bilayer. Movement represents an increase in the entropy or disorder in the system .

Do you think that the frequency of echolocation sounds from bottlenose dolphins will be higher or lower than that of the blue wh
Alik [6]

Answer:

The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.

However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.

Hope that answers the question, have a great day!
