In biochemistry, aligand is a substance that forms a complex with a biomolecule to serve abiological purpose. In protein-ligandbinding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.
Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. An endocytotic process occurs and the ligand is ingested.
A very well studied example of receptor mediated endocytosis involves the metabolism of cholesterol.
From the information given, i can't give you an actual number. But I can tell you that if a rock has a high porosity (its very porous which means that liquids can easily pass through) and has high permeablilty (liquids are able to enter the rock with ease), then groundwater could flow through this rock easily and faster than a rock that has a low porosity and low permeability.
Answer:
The two factors that decrease the size of a population are mortality, which is the number of individual deaths in a population over a period of time, and emigration, which is the migration of an individual from a place. and then also birth rate
Explanation:
Answer:
As we move through the visible spectrum, red to violet (from right to left in the image), the wavelength _____ decreases_____ and the frequency ____________. .
Explanation:
On the right side are the infrared waves and on the left the ultraviolet spectrum
The relationship between wavelength and frequency is inversely proportional (longer, shorter and vice versa)
