Article: Dinoflagellates   photosynthesize during the day, and to do so effectively they need twelve solid hours of light. This can be achieved by allowing the algae to get natural sunlight or controlling the light carefully with a lamp inside a closet or dark room.  If you use a lamp, it should be placed about three feet from the container. Do not place the light directly over the container; this will heat it up and kill the organisms inside. If you want the algae to luminescent predictably, it is necessary to keep them on a strict light schedule. Turn on the light at the same time in the morning and turn it off at the same time at night (you can use a light timer to help you). The algae's circadian rhythm will synchronize with the light schedule. It is possible to arrange a light schedule so that luminescence occurs during the day. This is useful if you are using it to teach children in a classroom. Set up the grow lamp to shine on the algae overnight, and keep it in a dark closet during the day. Dinoflagellates flash when water or another substances stimulates them by pressing against their cell walls. To watch them luminesce, pick up the container and gently swirl the water inside. If they received enough light during the day, they will begin to light up and flash.  Don't shake the container too hard, as it will wear out the dinoflagellates and cause them to stop flashing more quickly. Don't shake the container too often, since this also causes dinoflagellates to become exhausted. They need a period of recovery after luminescing. Over time, if the conditions are right, you will see the algae multiply. You can separate it into more containers and mix it with additional grow solution. The luminescence won't be as bright at first, since it will take a few weeks for the algae population to restore itself. Dinoflagellates usually expire after this period. Buy another culture, and consider experimenting with a different dinoflagellate this time.
Question: What is a summary of what this article is about?
Set up a light cycle. Stimulate the algae and watch it glow. Divide the algae into more containers. Keep the algae for four to six months.
Article: Before you pluck up the courage to ask this boy out, relax your arms, clear your face, speak up and smile. This will indicate that you're approachable and bubbly when you come to meet this boy. Boys don't really fancy girls who hide behind their hair and are too shy. They like girls who stand out. Make yourself known.  Make sure you're clean and look pretty if/when you ask him out. In fact, make sure you're clean and pretty whenever you see him. You never know when he might pop up, so be prepared. Remind yourself, if you're nervous, that it's only a boy. You may have a big, fat crush on him — and he's probably adorable — but it's not a big deal if you mess up or he says "no," for whatever reason. You're special, and other boys would be lucky to have you. Ask him yourself. Don't get a friend to do it. You'll make a bigger impression on him if you ask him yourself. Decide whether you want to ask him in person or over IM or Facebook or the like. In person is probably best, but if you're super nervous, you can do IM in a pinch. One of the biggest mistakes a girl can make is to pass the boy a note during class. This boy will almost definitely tell all his friends about it, and we all know what boys are like — they'll hound you about it! If he's alone, tell him you want to ask him something and go for it, head on! (Hesitation tells him that you might not be able to hold a conversation.) However, if he's with his friends, ask him to talk to you in private and ignore his friends if they start to snigger. You don't care, right? You only care about the boy, not his friends.

Be confident. Make the situation comfortable.
Article: A good place to start is by importing all the personal contacts from your phone. After that, you can start expanding your search to include business connections, friends of friends and casual acquaintances.  In order to multiply your money-making opportunities, you’ll want to make sure that you’re able to hook as many eyes and ears as possible. Encourage your close friends and associates to begin using the app so that you can expand your professional network. With your audience now in place, you can begin zeroing in on who has the most to gain from your services. Tailor the content of your story feed to captivate the attention of these people, or communicate with them personally to really wow them.  Athletes, for example, will be more likely to want nutritional supplements, while new mothers may be interested in a seminar on how to manage time more effectively.  Analyze prospective customers based on the activities and interests listed on their social media profiles. One of the most useful features of WhatsApp is the ability to create closed groups of users based on some common interest or classification. A well-structured group can serve as a pool of contacts who you can guarantee will be responsive to your branding and promotions.  Your groups should have a definite purpose—for instance, they might give customers a place to offer suggestions about things they’d like to see in the future or provide feedback about a new product line.  Become a part of as many different groups at one time as you want. This will give you the freedom to fine-tune your marketing strategies even further. WhatsApp still doesn’t have the visibility of apps like Facebook, Twitter and Instagram. Fortunately, clever users can work through these other programs to build a bigger following. Make regular posts to keep your contacts updated, then guide them toward your WhatsApp profile for more information.  Let your friends on social media know about exclusive offers and other content that they’ll only be able to get by connecting with you on WhatsApp. Use WhatsApp as an alternative to other person-to-person chat options like Facebook Messenger or Snapchat.
