Question: Kinect is a "controller-free gaming and entertainment experience" for the Xbox 360. It was first announced on June 1, 2009 at the Electronic Entertainment Expo, under the codename, Project Natal. The add-on peripheral enables users to control and interact with the Xbox 360 without a game controller by using gestures, spoken commands and presented objects and images. The Kinect accessory is compatible with all Xbox 360 models, connecting to new models via a custom connector, and to older ones via a USB and mains power adapter. During their CES 2010 keynote speech, Robbie Bach and Microsoft CEO Steve Ballmer went on to say that Kinect will be released during the holiday period (November–January) and it will work with every 360 console. Its name and release date of 2010-11-04 were officially announced on 2010-06-13, prior to Microsoft's press conference at E3 2010.

Question: Most mutations within genes are neutral, having no effect on the organism's phenotype (silent mutations). Some mutations do not change the amino acid sequence because multiple codons encode the same amino acid (synonymous mutations). Other mutations can be neutral if they lead to amino acid sequence changes, but the protein still functions similarly with the new amino acid (e.g. conservative mutations). Many mutations, however, are deleterious or even lethal, and are removed from populations by natural selection. Genetic disorders are the result of deleterious mutations and can be due to spontaneous mutation in the affected individual, or can be inherited. Finally, a small fraction of mutations are beneficial, improving the organism's fitness and are extremely important for evolution, since their directional selection leads to adaptive evolution.:7.6
Is there an answer to this question: What are mutations that lead to amino acid sequence changes but leave the protein functioning similarly called?

Answer: conservative mutations


Question: Presbyterians place great importance upon education and lifelong learning. Continuous study of the scriptures, theological writings, and understanding and interpretation of church doctrine are embodied in several statements of faith and catechisms formally adopted by various branches of the church, often referred to as "subordinate standards". It is generally considered that the point of such learning is to enable one to put one's faith into practice; some Presbyterians generally exhibit their faith in action as well as words, by generosity, hospitality, as well as proclaiming the gospel of Christ.
