1) Excitation brings about contraction.
2) Contraction leads to an increase in blood pressure.
3) Changes in blood pressure results in the opening and closing of the heart valves.
4) The opening and closing of heart valves then regulates the flow of blood and it's volume.
The three<span> basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. Cocci may be oval, elongated, or flattened on one side. Cocci may remain attached after cell division.</span>
Answer: False
Explanation:
This is a false statement because researches have shown that Adrenaline is helping and it is good for long-term memory and if we have lots of Adrenaline that is making our brain work and remember better and more.
If we are recalling being insulted, falling, or something more, we can still retrieve those memories because of the Adrenaline and that means that it is not decreasing the ability to remember the trauma.

Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
