In one sentence, describe what the following article is about: The main reason to post while riding is to avoid being jostled around in the saddle during a particularly bumpy gait - the trot. This makes things more comfortable for the rider and is easier on the horse's back.  Once you become more experienced with the rising trot, it is also possible to change the horse's rhythm simply by posting more quickly or slowly. The horse will alter his rhythm to match with your own, thus sometimes eliminating the need for hand and leg signals. Urge your horse into a steady forward trot. Now, pay attention to the horse's strides - notice how the trot has two beats? Good. This will help you to understand how posting works.  During a trot, the horse's left hind leg and right front leg (which are diagonal to one another) move simultaneously, and vice versa. This is what riders are talking about when they refer to "diagonals" - the simultaneous movement of diagonal front and back legs. These diagonals will greatly influence your rising trot. When performed correctly, the rider will rise from his/her seat when the inside hind leg and outside front leg are moving forward and sit when the outside hind leg and inside front leg are moving forward. The reason for this is because the horse's inside hind leg is the one which propels him forward. Rising out of your seat while this leg is in motion will encourage the horse to stretch the leg further under his body, and therefore producing a more effective stride. At first, it can be difficult to tell which diagonal your horse is on. A good trick is to watch your horse's outside shoulder. You should rise out of your seat as his shoulder moves forward and sit back down as it moves back. If the movement is difficult to pinpoint, stick a bandage or piece of colored tape on the horse's shoulder. This makes the movement easier to see. Once you start posting your legs will likely be sore, but you'll gain more thigh muscles over time.
Summary: Understand why posting is done. Understand diagonals. Realize that posting should be done using your thigh muscles, not your legs.

The iPhone 5, 5c, 5s, and the original iPhone have the IMEI number engraved on the back of the phone, near the bottom. If you need the MEID number, take the same number but ignore the last digit (IMEI is 15 digits, MEID is 14 digits).  GSM networks like AT&T and T-Mobile use IMEI numbers. CDMA networks such as Sprint, Verizon, and US Cellular use MEID numbers. If you are using an older iPhone, see the following steps. See this guide for details on removing the SIM card tray for your specific model. Your IMEI/MEID number is printed on the tray. If you are on a CDMA network (Verizon, Sprint, US Cellular), both codes will be printed as one. To determine the MEID number, ignore the last digit. This can be found on your iPhone's Home screen. This step works for any iPhone or cellular iPad. Tap "About" in the General menu. This will display your IMEI/MEID number. If you want to copy it to your iPhone's clipboard, press and hold the IMEI/MEID button in the About menu for a few seconds. A message will appear letting you know that the number has been copied. If your iPhone won't turn on, you can connect it to your computer and use iTunes to retrieve the IMEI/MEID number.  Plug your iPhone into your computer and open iTunes. Select your iPhone from the Device menu in the upper-right corner of iTunes and then click the Summary tab. Click the "Phone Number" entry next to the image of your iPhone. This will cycle through the ID numbers for your device. Copy the IMEI/MEID number. If both are displayed, check what carrier you use to see which number you need. GSM networks like AT&T and T-Mobile use IMEI numbers. CDMA networks such as Sprint, Verizon, and US Cellular use MEID numbers.

One-sentence summary -- Look at the back of your iPhone 5 or original iPhone. Check the SIM card tray of your iPhone 3G, 3GS, 4, or 4s. Open the Settings app. Tap General. Tap IMEI/MEID. Find the IMEI/MEID using iTunes.

Q: If you thought everything was going okay, but then had a really hard time in the exam, don't wait until progress reports or midterm grades are handed out. Waiting until after your grade comes out shows a lack of initiative; if you know you've done poorly -- especially if there's a good reason for it -- you should bring it up right away. Not only that, but term grades often can't be changed once they're entered into the system. (This also goes for assignments from the semester/quarter before.) If you are in this situation, try improving your grade for the upcoming marking period. Ask for extra-credit work so that you can shift your point average. If you want to talk your teacher and potentially challenge a grade you have received you need to understand the system they are using, how this influences grades and the limitations it imposes. Do they use a grading curve? Was it an especially high-performing class? Knowing these things can help you understand the process behind the grading of your papers. Your ability to question your grade is a lot more straightforward if the test was one which had objectively correct or incorrect answers. An essay question where answers are open to at least a degree of interpretation can be much more complicated and harder to dispute. In these cases you have to remember that the person marking is not a computer and subjectivity plays a part in their responses. In the case of an essay question, you can ask your teacher to go through your answer with you. Reading your essay together will give you the opportunity to understand in more detail how it was graded. Whether it's because you are making a good effort in class or you had a stumble along the road, you need a good reason in order for this to work. Don't try to blag it on the spot. Whatever you might think, your teacher isn't that dumb. If you are experiencing personal problems that have contributed to your grade, don't be afraid to talk to your teacher about it. Calmly and professionally say what you believe is wrong with your grade. Present other tests and assignments that demonstrate what you're capable of, and suggest the solution you think is reasonable. Be convincing and confident, but don't assume to know more or better than your teacher.  Find good assignments to use as examples or backup. If you can demonstrate that your low score was a fluke and shouldn't drag down your entire grade, you stand a much better chance of getting it changed. If the problem was that you had an unreliable teammate in a group project, don't blame it all on him/her or you'll seem like a bad team player. Instead, say that if you'd given him/her extra help, you wouldn't have done as well on your half of the project, and that it's not fair to get a bad grade because of somebody else's work.
A: Approach your teacher before you get the grade. Understand the grading system. Think about what kind of exam it was. Identify the reasons why you may deserve a better grade. Make your case.

Problem: Article: Most flowers that are considered annuals are self-pollinating. Each self-pollinating flower has a stamen to produce pollen, a stigma to collect pollen, and a pistil leading to the ovule. Identify these structures in the flower. This will allow you to collect and move pollen to and from the correct structures.  The stamina (or stamens) look like little antennae that carry pollen. The pistil is usually in the center of the flower, and the stigma is on top of the pistil. The ovule can be found at the base of the pistil. Some self-pollinating flowers, such as lilies and roses, are also capable of cross-pollination. Pollen reaches the ovule by travelling down the pistil. The stop of the pistil, or stigma, is designed to collect pollen and move it down to the ovule. Use your brush to transfer pollen onto the stigma.
Summary:
Identify organs located on the flowers for self-pollinating plants. Transfer the pollen to the ovule.
