The correct answer is (c.) Animal-like protists differ from plant-like protists as the animal-like ones are heterotrophic in nature, whereas the plant-like protists are autotrophic. Heterotrophic is an organism in which uses carbon for growth and autotrophic is an organism in which produces complex organic compounds.
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:
Explanation:
Scientists collect their evidence through experimentation and/or observation.
Explanation:
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
