The scientific method or scientific analysis can be defined as the objective search for the truth. When a scientist does an experiment, it is essential that he reports every observation in the result, whether it is in uniformity with the experiment or not. Many scientific discoveries are made based on the unusual findings. The failure to report these unusual findings during an experiment might result in the loss of vital information.
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.

If the choice is true or false, the answer is true. Most of hominins were probably nearly as efficient at bipedal locomotion as humans. However, the bones of their pelvis were shorter from top to bottom than humans. This made their pelvis more stable for weight which supports standing upright or moving bipedially.
