This pertains to the structure of proteins. Secondary structures are stabilized by the presence of hydrogen bonds. The common types of secondary structures of proteins are the alpha helix and the beta sheets, each performing different functions.
Primary structure of protein is the peptide molecule comprised of peptide bonds. Once these peptide grows long enough, it will either be arranged into alpha helices or beta sheets stabilized by hydrogen bonds and this is the secondary structure. Once there is protein folding involved in the secondary structure of protein, then the folded protein is called the tertiary structure (or a protein subunit). When protein subunits come together to perform a specific function, then that is the quaternary structure.
Attached is a figure concerning the protein structures.
Answer:
Pressure sensing cells
Explanation:
Merkel cells provide information on pressure, position and deep static touch features such as shapes and edges. They are tactile sensors on the business of mechanotransduction. They encode surface features of touched objects into perception, but also have to do with proprioception.
That is false because plants grow everywhere and I doubt anyone fertilized the Amazon rainforest
anyway ITS FALSE bro
Which signal are you talking about?
Thunder is caused by the extremely rapid expansion of air around a bolt of lightning due to the very high temperature. It is also caused by the change of pressure around a lightning bolt.
Hope that helped you.
