How does the villi etxend into the lumen for nutrient absorption?

Biology
1 answer:
Romashka [77]4 years ago
8 0
First the villi has a thin wall, which is only 1 cell thick this can increase the rate for diffusion and active transport of digested food into the blood since the distance is short.
The network of blood capillaries can also speed up the process.

polet [3.4K]
I believe this is an example of frameshift mutation.
Frame shift mutation is a type of mutation that is caused by addition or deletion of a base pair or base pairs in the DNA of a gene resulting in the translation of the genetic code in an unnatural reading frame from the position the position of the mutation to the end of the gene.

Osmosis is the passive movement of water, but it follows almost completely opposite laws of physics when compared to the diffusi
Alja [10]

Answer:

False.

Explanation:

Note that, osmosis is considered as the passive movement of water because,it involves the movement of water from a region or area where concentration is high to the region or area of low concentration. This is the reason why it is compared to or described as a type of diffusion.

This process is known as passive transport or passive movement of water. And it is known to be water specific process.

That is why it can be compared to diffusion of ions or other small molecules in physics.

Which of the following pairs of elements would most likely form a salt?
PSYCHO15rus [73]
A salt is an ionic compound which needs a positive charge ion and a negative ion charge to form a salt.This means that the pair of element should be a metal and non-metal.This is simply because metal atoms tend to lose negative charge electrons and form positive ions while non-metals tend to receive the electrons from the metal atom to form negative charge ions.So answer is Cl and Li.

Bacterial infections and viral infections progress through an identical sequence of events during the immune response. bacterial
Vaselesa [24]
The statement above is FALSE.
There are differences in the complex interactions that are formed with the host's system when a bacterial or viral infection occur and the two types of infection do not progress through similar sequences of events during immune response. The body system usually react to disease causing bacteria by increasing the local blood flow and signalling appropriate cells to attack the bacteria. For virus, virus are usually very adaptive to their host's system and therefore are very good at escaping the immune system. The body system has put in place many mechanisms to prevent this. The specific sequence of immune response depend on the type of virus and its interaction with the host cells.
