Cells are the building blocks of life. All living things have cells - from small, single-celled organisms like bacteria to large, multicellular organisms like humans.

Cells have specific functions that help keep these varied creatures alive and kicking. In order to make these functions happen, chemical reactions occur within cells. Oftentimes, these chemical reactions are sped up by a special kind of protein called an enzyme.

In this article, we’re going to answer a few questions: what are enzymes, what are enzymes made of, and what types of enzymes exist.

One of the hardest parts of learning a romance language—especially one like Spanish—is verb conjugation.

In Spanish, the way a verb is conjugated depends on a number of factors, including the subject, the verb tense, and the purpose of the sentence itself. That means that there are actually many versions of each verb, all of which mean something slightly different. And because so much of understanding Spanish revolves around verbs, it’s an important (though pretty confusing) part of learning Spanish as a second language.

If you’re taking the AP Spanish exam, ser is one of the most critical verbs that you need to know—and know how to conjugate. Unfortunately, the conjugations for ser can be pretty tricky. But we’re here to help. In this article, we’ll give you every possible verb conjugation for the Spanish verb ser, which means “to be.” We’ll even give you a quick rundown on what ser means and when to use it!

So… ¡si estan listos, vamos!

These predictions have been updated in March 2019 to reflect the latest possible data.

What do those little sideways carat symbols mean? They're inequalities! Inequalities can be difficult to get a handle on, especially because the greater than and less than signs look so similar. But these symbols are very useful, because they help us show the relationship between numbers or equations in a way that doesn't just say that they're equal.

Learning to read and understand poetry is tricky business. Between the tough terminology—what is synecdoche, anyway?!—and complicated structure, it can sometimes feel impossible to understand what a poet is trying to say. Unfortunately, if you’re going to take the AP Literature exam, you’re going to have to figure out how to quickly read and understand poetry.

One of the best ways to get a handle on poetry is to read a poem along with a detailed explanation of both what the poem means and how the poet conveys that meaning.

To do this, we’re going to take a look at Dylan Thomas’ “Do not go gentle into that good night,” one of the most famous poems of the 20th century. Not only will you have a handle on the poem’s overall message, but you’ll also understand the most important techniques Dylan Thomas uses to convey that meaning to the reader.
