The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.
<h3>What is Active transport?</h3>
Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.
During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.
But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.
The complete question is as follows:
What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?
- Lungs
- Stomach
- Small intestine
- Liver
Therefore, the correct option for this question is C, i.e. small intestine.

The answer is d
Basically everywhere
Answer:
1. Space-filling
2. Ribbon model
3. Wire frame
4. Simple shape
5. Simplified diagram
Explanation:
"attached is the question"
A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand. A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent. Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein. Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows. Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms. A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein. A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.
Answer:
a. This quote means, if you believe that something you excel, or your ability to do something, in is ingrained in your mind you will eventually get to a point where you won't know what to do or your won't be good at it anymore and you will break, and not know what to do because you think your skill was ingrained into your mind. If you believe you can learn something to become better at it then you will be able to get past that point because you will know you just have to learn more about it.
Explanation:
Sorry if this isn't a very good answer I'm not in college!
Rainwater can replace or replenish freshwater sources.
Precipitation, such as rainwater, is the source of freshwater on Earth.
When the amount of surface freshwater increases, so does the amount of groundwater.
Human activity, such as taking a bath, may change the quality of a freshwater resource. :)
