What is the best way to prepare for the SAT?
Two words: (1) Mindset, and (2) Practice. I went into my first exam knowing that I could retake the exam as many times as needed, and knowing that I could superscore the exam so I wouldn't be crushed if the first section or if even the first question was too difficult. Having this mindset was so important, and I attribute my perfect score to having this mindset. Mindset isn't everything though! Practice is also important, and that involves motivation. I found it vital to have a tutor to guide me through practice problems, push me through practice exams, and motivate me by tracking my progress and bringing up old questions that I had previously missed, but with guidance, now easily answered. The motivation to keep practicing these test-taking skills is so important especially for the SAT, and I personally found tutoring to be a great source of motivation.
Compare operant conditioning designed by Skinner to the social learning theory by Bandura.
Operant conditioning involves a token economy where each individual has certain behavior that is encouraged, rewarded, and reinforced while his/her/their unwanted behavior is punished. Bandura's social learning theory involves learning through observation, so an individual learns by watching another individual be punished and/or rewarded for their unwanted or wanted behavior, respectively. Here, the learner is not directly rewarded/punished for their behavior.
What is involved in the development of chronic myelogenous leukemia?
A translocation between chromosomes 9 and 22. Chromosome 9 contains the ABL gene, a proto-oncogene and chromosome 22 contains the BCR gene, a highly active gene. Following the translocation of a segment of chromosome 9 to chromosome 22, creating the Philadelphia chromosome, the fusion ABL-BCR gene is continually active, causing constant cell proliferation and thus CML.
