Biology
A. Metamorphosis
In some animal species, the growth of its development and undergo metamorphosis. Events of metamorphosis is a gradual change in body shape starting from larva to adult. Metamorphosis occurs in insects and amphibians.
Examples of amphibians are frogs undergo metamorphosis. Growth and development of the frog starts from the zygote is formed. The zygote then develops into an embryo. One week later, it becomes a larva which often do you call a tadpole / tadpole. At first tadpoles breathe with gills three out, but later changed to the gills.Some time later formed gill cover and the rear legs. After only three months, the tadpoles metamorphosed marked the formation of the lungs and four legs, loss of gills and tail, and a frog shape. Properties different from the properties of frog tadpoles. Tadpoles live in water as herbivores, while land-dwelling frogs are carnivorous.Newly hatched insect larvae tangible. Some insects such as butterflies and dragonflies, larval form is much different from the adult form. Butterfly larvae are called caterpillars have chewing mouth type, while butterflies have sucking mouth type. Dragonfly larvae live in water, while the adult dragonfly can live on land and fly.However, some insects have a similar shape when newly hatched to adulthood. Examples are the grasshoppers, cockroaches, and crickets. Under the process, the metamorphosis of insects can be divided into two, namely metamorphosis and incomplete metamorphosis.
a. Perfect MetamorphosisComplete metamorphosis is characterized by a phase called the pupa or chrysalis. Forms of insect larvae with adults is much different.Stages in the metamorphosis is as follows. eggs? larva pupa (chrysalis) adult (imago) The eggs hatch into larvae. Larvae do not have wings and wing signs as well not exist. When a larva, insects are very active feeding. Larvae then pupate changing shape. Larvae to pupa there is a direct, but there is also a patron of the first to make a folded leaf, soil or fine sand, fine wood cuts, and other materials.Shelters around the pupa called a chrysalis or cocoon. In the pupa stage, the insect is actively feeding, although the metabolic process is ongoing. After passing through the pupa stage, the insect would be the adult (imago).
b. Incomplete metamorphosis (Hemimetabola)Insects that have incomplete metamorphosis, the newly hatched form of insects (nymphs) are not much different from the adult form of the insect (imago). A striking difference is the nymph has no wings. The wings will grow in stages so as to resemble the adult form. In general, nymphs and adult insects have the same properties. For example in crickets and grasshoppers. The order of the life cycle of insects that have incomplete metamorphosis is as follows. eggs (nymphs) adult (imago).
2. MetagenesisSome types of plants and animals there are experiencing metagenesis process. Metagenesis rotation is the process of life, namely between sexual and asexual phases. Animals and plants that have metagenesis will have two phases of life, that phase of life that reproduce sexually, and the pace of life that reproduce asexually.Metagenesis in plants can be observed clearly in seedless plants (spikes and moss). In plants, the male gamete formation takes place in the antheridium and female gametes in arkegonium. If the male gametes to fertilize female gametes, it will form a zygote.Zygotes grow into individuals that produce spores. This generation is called the phase of vegetative (asexual) or sporophytes. Spores that fall in the corresponding place will grow into new individuals that produce gametes. Because it produces gametes, the generation phase is called generative (sexual) or gametophyte. So forth offspring rotation occurs between the phases gametophyte and sporophytes. Mosses that often you find a gametophyte phase. While ferns that you see everyday is the phase of sporophytes.Descendants of the phase rotation between sporophytes and gametophyte is called metagenesis.Some of the lower animals also experienced metagenesis, for example, Obelia and Aurelia. Note metagenesis jellyfish (Aurelia).Jellyfish (Aurelia) have two kinds of life that is life when attached (polyp) and life moves freely (medusa).
Polynomial
In mathematics, a polynomial is an expression of finite length constructed from variables (also known as indeterminates) and constants using only the operations of addition, subtraction, multiplication, and non-negative integer exponents. For example, x2 − x/4
+ 7 is a polynomial, butx2 − 4/x + 7x3/2 is
not, because its second term involves division by the
variable x (4/x) and because its third term contains an exponent
that is not an integer (3/2). The term "polynomial" can also be used
as an adjective, for quantities that can be expressed as a polynomial of some
parameter, as in "polynomial time" which is used in computational complexity theory.
Polynomial comes
from the Greek poly, "many" and medieval Latin binomium,
"binomial". The word was introduced in Latin by Franciscus Vieta.
Polynomials
appear in a wide variety of areas of mathematics and science. For example, they
are used to form polynomial equations, which encode a wide range of problems,
from elementary word problems to
complicated problems in the sciences; they are used to define polynomial
functions, which appear in settings ranging from basic chemistry and physics to economics and social science; they are used in calculus and numerical
analysis to
approximate other functions. In advanced mathematics, polynomials are used to
construct polynomial
rings, a central concept
in abstract
algebra and algebraic
geometry.
MEANING OF LIFE BEING GRATEFUL
Life is the greatest gift given by God the Father to man as a great proof of his love. In this life we have received countless gifts of health, success, intelligence, body parts, and so forth. Also in this life, the people were given the freedom to do things.Nevertheless, God's hope that everything that humans do remain guided by faith. In a sense, keeping in mind of God as the giver of life.
God gives all things to man because of his love, not for pity or for other reasons so forth. Even so, God does not expect a return of luxury above all.

Those whose lives are always grateful for having a lot of happiness in life because they rely on God, so God is also happy to reduce the abundant blessings upon them.Confidence and work as possible is a form of gratitude for the gift of God. In addition, we can meuwujudkan gratitude with prayer and worship. Gratitude can also be done by sharing knowledge, wealth, ability, etc. for others.
· Conclusion:People are always grateful to be able to appreciate even the slightest experienced in his life. People who are grateful will never stop trying to do something when he was a failure and sadness. Failure and sadness are always seen as the flip side of opportunity to achieve success and happiness.
