Answer:
Symmetric encryption is faster than asymmetric encryption, but it cannot be used to provide non-repudiation of contracts.
Explanation:
Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic information. Symmetric encryption uses a single key that needs to be shared among the people who need to receive the message while asymmetrical encryption uses a pair of public key and a private key to encrypt and decrypt messages when communicating. Symmetric encryption cannot be used for non-repudiation because the key is shared by both parties, making it difficult to prove who created and encrypted the document.
Answer:
One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space, making the carnage even worse. At least that's the story. But how many birds really do die?
If you look around for statistics about bird deaths from wind turbines get you wildly different numbers. Some say just 10,000 birds a year
Explanation:
Answer:
True
Explanation:
Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.
Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.
These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.
An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.
Answer:
The correct answer is methane . Nature constitutes most of the substances made up of organic compounds. These compounds have carbon atoms attached with hydrogen atoms with a chemical bond (very few compounds may not have this bond).
Answer:
Gap junctions within the intercalated disks
Explanation: Gap junctions within the intercalated disks allow impulses to be propagated from one cardiac muscle cell to another. It allows sodium, potassium, and calcium ions to flow between adjacent cells, propagating the action potential, and ensuring coordinated contractions.
