Put simply, a circuit is a closed conducting wire loop with some elements in the mix, such as batteries, resistors, and capacitors. Only batteries and resistors are covered in AP® Physics 1; Physics 2 also covers capacitors. In this article, we’ll review the characteristics of circuits, resistors, and capacitors and do some example problems similar to those on the AP® Physics 1 and 2 exams.
Through this AP® Psychology study guide, we’ll take you through three super easy steps to make sure that you’ve got all your bases covered on the day of the exam. The steps are: figuring out exactly what content will be covered on the exam, understanding the format of the exam, and finally practicing by testing yourself over and over again.
Congratulations! You’ve made it halfway through your high school career. As we’re sure you know, now is the time to start thinking about college choices. The first exciting step is to take the PSAT®/NMSQT. This guide walks you through the test, explains how to understand your score and gives you an idea of what a good PSAT® score is for your junior year. Look forward to taking the PSAT®/NMSQT at your school sometime in October or November.
The PSAT®s are the first daunting test on the way toward your college career. You probably have a bunch of questions: what is on the test, how to know if you did well, and what it means to have a good PSAT® score for your sophomore year.
The statistics section of the AP® Biology exam is without a doubt one of the most notoriously difficult sections. Biology students are comfortable with memorizing and understanding content, which is why this topic seems like the most difficult to master. In this article,The Chi Square Test: AP® Biology Crash Course, we will teach you a system for how to perform the Chi Square test every time. We will begin by reviewing some topics that you must know about statistics before you can complete the Chi Square test. Next, we will simplify the equation by defining each of the Chi Square variables. We will then use a simple example as practice to make sure that we have learned every part of the equation. Finally, we will finish with reviewing a more difficult question that you could see on your AP® Biology exam.
The word meiosis originates from the Greek language. It means to lessen; this refers to the lessening of the number of chromosomes within the cell. Meiosis is the process of chromosomal reduction in eukaryotic cells (plants, animals, and fungi), which leads to the production of germ cells (gametes/sex cells) needed for sexual reproduction.
Purines and pyrimidines are the two families of nitrogenous bases that make up nucleic acids – in other words, they are the building blocks of DNA and RNA. While they are similar in many respects, there are a number of key differences between them that you will be expected to know for the AP® exam. Before we get into those, however, let’s make sure you understand what purines and pyrimidines are so you can recognize questions about them even if the wording is tricky.
Heredity is the passing on of characters from parents onto their progeny. In some organisms, like humans, a parent passes on one copy per gene to their offspring and as a result, the progeny gets two copies in total from its parents. These organisms are called diploids (2n).
Meiosis is how eukaryotic cells (plants, animals, and fungi) reproduce sexually. It is a process of chromosomal reduction, which means that a diploid cell (this means a cell with two complete and identical chromosome sets) is reduced to form haploid cells (these are cells with only one chromosome set). The haploid cells produced by meiosis are germ cells, also known as gametes, sex cells or spores in plants and fungi.
Mitosis is the process whereby a cell reproduces asexually to produce two identical daughter cells. This occurs via nuclear division. Before mitosis, the number of chromosomes in the cell is doubled via chromosome replication, transforming the cell from a diploid (2n) cell to a tetraploid (4n) cell.
