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;
The first choice (A) is an unsaturated fatty acid.
Explanation;
-An unsaturated fat is a fat or fatty acid in which there is one or more double bond in the fatty acid chain.
-A fat molecule is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. In this case, the unsaturated fat (A) is polyunsaturated.
Since the rate of flashing depends on the rate of reaction, it means that fireflies will flash slower during cold weather.
<h3>How does temperature affect rate of reactions?</h3>
Temperature affects the rate of reaction such that reactions are faster at high temperatures and slower at low temperatures.
Thus, since the rate of flashing in fireflies depends on the rate of reaction, cold temperature means that the rate of flashing will be low as compared to warm temperature.
In other words, fireflies will flash lower during cold weather and vice versa.

Answer:
The correct answer is - tight junctions.
Explanation:
Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.
Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.
Thus, the correct answer is - tight junctions.
