In one sentence, describe what the following article is about: Biology textbooks have really good questions at the end of each chapter that reinforce the concepts that you need to understand from the material. Try answering the questions and see how many you can get through. Take note of the questions that are more difficult to answer. Revisit your notes on these topics and/or reread that part of the chapter.  If you're having a lot of difficulty answering these questions, seek extra help from your classmates or teacher. Avoid walking out of class and forgetting about everything you just learned. Reviewing your notes later that evening or the next day can help you synthesize what you have learned. When reviewing, ask yourself if everything makes sense. If something stands out that confuses you, reread the material on that concept in your textbook. If it still doesn't make sense, ask your teacher about it in the next class. Because biology can be difficult for many students, you must put in the time to do well. If you set aside time every night or every other night for biology, you will get into the good habit of frequently studying. You will thank yourself later when you don't have to cram for the exam because you have been reviewing everything this whole time.  Stick to your study schedule and make it a habit. If you skip 1 day, be sure to get back on track the next day and not let yourself slip into not studying multiple days in a row. Even if you're busy, plan to spend 15 minutes per day reviewing your notes. This can make a big difference! Creating mnemonic devices can be really helpful when studying biology. For instance, you could create a mnemonic to help you remember the order of the substrates in the Krebs cycle. A phrase like, “Citrate Is Krebs Starting Substrate For Making Oxaloacetate” can make it easier to remember Citrate, Isocitrate, Alpha-Ketoglutarate, Succinyl CoA, Succinate, Fumarate, Malate, Oxaloacetate. If you have access to exams from previous years, try taking them and see how much of you get right. If you don't have access to these, study your quizzes and previous tests for an idea of the types of questions you will get asked.  Answering questions from old tests will give you an idea of what you need to keep studying and what topics you have mastered. You could also make up your own quizzes to test yourself on the material. Focus on the concepts you have the most difficulty with. This helps you process the information in a meaningful way, instead of just trying to memorize it.
Summary: Answer the questions at the end of each chapter. Review your notes within a day of each lecture. Set aside time specifically for studying biology. Use mnemonic devices. Study old quizzes and exams before tests.

In one sentence, describe what the following article is about: Use a large sheet of white or tan fabric. You can also use a bed sheet if you don't have a large sheet of fabric. You won't need to sew your toga, you'll just have to tie the corners of the sheet in a knot.  Use a fabric that is not too stiff. A fabric that flows or drapes will help create the draped look of a toga. If you're worried about modesty or warmth, you can always wear a white top and white bottoms underneath your toga. The longer length of the sheet should be horizontal when you're ready to wrap your sheet around your body. Hold the sheet so that it is against your back. Once your sheet is in place, wrap it length wise around your body with the top end of the sheet just under your armpits. If the sheet is too long, fold the top over a few inches to make your sheet your desired toga length. Reach around your back to pull the sheet corner across your back and over your right shoulder. This will serve as the strap of your toga. (Most togas usually have a strap over just one shoulder). Hold this corner in place while you continue to wrap the other end of your sheet around your body. Wrap the left end of the sheet around your entire body one time. Once the end of the sheet is back in the front of your body, pull the left corner of the sheet toward your right shoulder and tie it in a knot with the right corner of the sheet.  Double knot the sheet corners to make sure your toga strap is secure. Tuck the ends of the corners into the knot or into the fabric so that they are no longer showing. Look at Make a Toga out of a Bedsheet for detailed instructions on multiple ways to make togas.
Summary: Make your own traditional looking toga using a sheet of fabric. Hold your sheet so that it is sideways. Wrap the right end of your sheet around the front of your body and around to your back. Finish making the toga.

In one sentence, describe what the following article is about: There are approximately 600 individual species listed in the Quercus (Oak) genus--most are trees, though a few are shrubs. Some are deciduous, some evergreen, some semi-evergreen.  Oaks are mostly native to woodlands in the Northern Hemisphere, but they vary widely, from cold and temperate forests across North America and Europe to the tropical jungles of Asia and Central America. Some evergreen oak trees (particularly certain American Species) are commonly called "Live Oak". This grouping name describes several species with an evergreen growth pattern, and it does not reflect any taxonomic classification group--in some cases, these species are only distantly related. Thus, evergreen oaks (Live Oaks) can be considered as a type of oak tree, but only insofar as they're an evergreen oak variety. Find an illustrated field identification guide to take with you to the woods; pictures will help you immensely in your quest to name specific species of oak.  In North America, oak trees are split into two main groups: "red oak" and "white oak". Red oaks tend to have darker bark, and lobed leaves that come to a point; white oaks tend to have lighter bark, and leaves with rounded lobes.  Common "white oak" species include chinkapin oak (found in limestone-rich soils), live oak, blackjack oak (found on dry ridges), shingle oak (found on moist slopes), swamp chestnut oak (found in wetlands), white oak (found in various ecosystems), swamp white oak (found in wetlands), and overcup oak (found on stream-banks, in marshy bottomlands).  Common "red oak" species include water oak (found near stream-banks and lowlands), northern red oak (found in various habitats), southern red oak (found on moist and dry slopes), scarlet oak (found on dry slopes), willow oak (found on moist slopes), pin oak (found in wetlands), and cherrybark oak (found near moist slopes and bottomlands).
Summary:
Behold the breadth of the oak family. Understand which oak species grow in your region.
