Scientific classfication
Phylum:Magnoliophyta
Class: Magnoliopsida
Order: Asterales
Family: Asteraceae
Genus: Helianthus
Species:
H. annuus
The sunflower (Helianthus annuus) is annual plant native to the Americas in the family Asteraceae, with a large flowering head (inflorescence). The stem of the flower can grow as high as 3 meters tall, with the flower head reaching up to 30 cm in diameter with the "large" seeds. The term "sunflower" is also used to refer to all plants of the genus Helianthus, many of which are perennial plants.

Rainbows are optical illusion and meteorological phenomena that cause a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the earth’s atmosphere. They take the form of a multicolored arc, with red on the outer part of the arch and violet on the inner section of the arch. More rarely, a secondary rainbow is seen, which is a second, fainter arc, outside the primary arc, with colors in the opposite order, that is, with violet on the outside and red on the inside.
A rainbow spans a continuous spectrum of colors. Traditionally, however, the sequence quantized. The most commonly cited and remembered sequence, in English, is Newton’s sevenfold red, orange, yellow, green, blue, indigo and violet."
Rainbows can be caused by other forms of water than rain, including mist, spray, dew, fog, and ice. Moreover, rainbows can have shapes other than a bow (arc), including stripes, circles, or even flames.
Butterflies are the adult flying stage of certain insects belonging to an order or group called Lepidoptera. Moths also belong to this group. The word "Lepidoptera" means "scaly wings" in Greek. This name perfectly suits the insects in this group because their wings are covered with thousands of tiny scales overlapping in rows. The scales, which are arranged in colorful designs unique to each species, are what give the butterfly its beauty.
Like all other insects, butterflies have six legs and three main body parts: head, thorax (chest or mid section) and abdomen (tail end). They also have two antennae and an exoskeleton.
The difference between a butterfly and a moth?
Both butterflies and moths belong to the same insect group called Lepidoptera. In general, butterflies differ from moths in the following ways:
(1) Butterflies usually have clubbed antennae but moths have fuzzy or feathery antennae.
(2) Butterflies normally are active during the daytime while most moths are active at night.
(3) When a butterfly rests, it will do so with its wings held upright over its body. Moths, on the other hand, rest with their wings spread out flat. Butterflies will, however, bask with their wings out-stretched.(4) Butterflies are generally more brightly colored than moths; however, this is not always the case. There are some very colorful moths.

Global warming.....
What do you understand about it???
Is it when the earth become warm and hot we can directly assume it as global warming??
Ha...actually 'Global warming ' is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century.The average global air temperature near the Earth's surface increased during the hundred years ending in 2005. The Intergovermental Panel on Climate Change(IPCC) concludes that "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in greenhouse gas concentrations via an enhanced greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.
While the effect of increasing global temperature is expected to cause sea level to rise, an increase in the intensity of extreme weather events, and significant changes to the amount and pattern of precipitations. Others are expected effects of global warming include changes in agricultural yields, modifications of trade routes, animals extinctions and increases in the ranges of disease vectors.
Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is on going political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.

So, from that article I would like all of you try to feel and imagine how is our life in the future due to the increasing of Global Warming in the world now......please my frenz.....
