why do some plants have leaves that are not green

Q. My tree has red leaves all year. How does a plant support itself without green chlorophyll? A. Some parasitic plants lack chlorophyll entirely and steal the products of photosynthesis from their green hosts, said Susan K. Pell, director of science at the Brooklyn Botanic Garden. Other plants, like a red-leafed tree, have plenty of chlorophyll, but the molecule is masked by another pigment. Chlorophyll absorbs red and blue light, Бreflecting, and thus appearing, green,Б Dr. Pell said. Chlorophyll uses this electromagnetic energy, along with carbon dioxide and water, to make glucose and oxygen. Most plants also have other pigments: carotenoids, which usually appear yellow to orange, and anthocyanins, which are red to purple. One pigment usually dominates. So a plant with red leaves

why do some people cry more than others

My mom comes from a family full of criers. She and her sisters all tear up at the first few bars of "God Bless America" for pete's sake. Though, I thought I was safe from this fate, I, too, have noticed that I've been tearing up more and more in my not-so-young age. It made me wonder if some people, through a mix of hormones, genetics, and who knows what else, are more likely to reach for the tissues than others. Here's what we found out. As you'd expect, there are different types of crying -- there's crying when you're hurt, crying when you're sad, crying when you're moved by something beautiful, etc. -- but they're all usually caused by a buildup of energy or an intense emotion. And, to make things more complicated, what makes one person cry won't necessarily make the person next to

why was the stamp act congress important

The Stamp Act Congress also set a precedent for future colonial meetings, and when Britain passed the Intolerable Acts in 1774 to punish Boston for its role in the Boston Tea Party a year earlier, another meeting was called in Philadelphia, known as the First Continental Congress. Many of the same delegates from the Stamp Act Congress were present, and of the colonies that would eventually declare independence, only Georgia was absent. This Congress collectively decided on another boycott of British goods, and arranged for a future meeting several months later. The Stamp Act Congress met in the Federal Hall building in New York City between October 7 and 25, 1765. It was the first colonial action against a British measure and was formed to protest theP issued by British Parliament on

why indian stock market is down today

Is Indian market the only one concerned about global developments while all other emerging markets are ignorant? Indian markets seem to have reacted to a China downgrade by S P, a UK downgrade by Moodyвs, and a once-in-a-generation change in the US already named as the вGreat Unwindingв. Foreign investors seem to be selling their holding in the Indian stock markets while increasing it in other emerging markets, especially in other member countries of BRICS (Brazil, Russia, China and South Africa). Apart from India, all other markets continue to remain strong. China equity funds extended their longest inflow streak since the third quarter of 2014 while Brazil equity funds hit a 17-week high on continued inflows. A rally in commodities is helping a sustained rally in Brazil. Chinese markets

why do my underarms smell after a shower

Cleanliness is next to godliness. If you have ever stood next to a woman who has armpit odour, you would realise that it is very much nauseating. Most of the time it is very difficult to tell the person what she should do because you do not want to embarrass or offend her. Armpit odour is an embarrassing problem a lot of women have to deal with on a day of day basis. Keeping very good hygiene by showering regularly and well is very important. Water washes away the bacteria which cause the smell. It is advisable to shave your armpit regularly to prevent unnecessary hair growth. Rubbing lime juice under the armpit helps to remove bad odour because of its acidic nature. Lime juice can, however, have detrimental effect upon the skin if it is dry or broken. Sometimes it discolours your

why do we give diamond engagement rings

Although the ancient Egyptians are sometimes credited with having invented the engagement ring, and the ancient Greeks with having adopted the tradition, the history of the engagement ring can only be reliably traced as far back as ancient Rome. In many countries, engagement rings are placed on the ring finger of the left hand. At one time it was believed that this finger contained a vein (the ) that led to the heart. This idea was popularized by in A treatise of Spousals, or Matrimonial Contracts (1686). The story seems to have its origin in the ancient Roman book Attic Nights by quoting 's Aegyptiacorum, where the alleged vein was originally a nervus (a word that can be translated either as "nerve" or "sinew"). The popular belief that an engagement ring was originally part of the which

why do my windows sweat in the winter

When the temp gets around 35 or below, my windows sweat really bad. It freezes around the frame and I have to scrape it off. Our home is 11 years old, but the windows have done this since it was new. My husband says it is the gas fireplace that we use that does it. I read that too much humidity would cause it, would a dehumidifier help? I have to go around every day and dry the windows. Can you help? Carol, We get a lot of questions about windows sweating in the winter. HereБs whatБs happening and why. When air warms, it expands which allows it to hold more moisture. As it cools down, it contracts until it reaches the saturation point and releases this excess water in the form of condensation. Common daily activities in your homeБsuch as cooking, showering, using unvented gas heat, and

 why do we need to study religious education

why do we need to study religious education

I think I shall repeat some comments, but want to add my voice. I am really encouraged by the many positive comments on here about RE. The criticisms of RE here seem to be basically three, and I shall address them: RE is not properly academic - no, it is not, in the sense that it is not only academic, and that is part of its great strength. RE does require academic work, but it values that academic thinking not for itself, but in the context of the whole of life as it is lived, and therefore is particularly well placed to motivate students' thinking, because it demonstrates relevance. For example, I set my Y7s voluntary homework of making Karah Parshad when doing Sikhism. Several did, and when they brought it in and we ate it, we discussed the process, and the taste and so on, not as a
