NAME: K Class: Form 2 URANUS CHEMISTRY PROJECT Air pollution Description of air pollution Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible‚ some invisible—that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered as air pollution. Air pollutant Carbon dioxide dioxide

Sources of air pollution refer to the various locations‚ activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel • "Stationary Sources" as smoke stacks of power plants‚ manufacturing facilities‚ municipal waste incinerators. Power plant is also used to refer to the engine in ships‚ aircraft and other

Five hundred million years ago‚ the invasion of land was under way. Why then? Astronomical numbers of photosynthetic cells had come and gone‚ and oxygen-producing types had changed the atmosphere. High above Earth‚ the sun’s energy had converted much of the oxygen into a dense ozone layer‚ a shield against lethal doses of ultraviolet radiation. Until then‚ life had not ventured above the surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes

In Vitro Reproductive Development of Peanut‚ Arachis hypogaea L.‚ as Influenced by Plant Growth Regulators‚ Sucrose and pH1 Q. L. Feng‚ H . E. Pattee*‚ and H. T. Stalkef ABSTRACT Research on in vitro embryo culture in Arachis has the objective ofrescuinginterspecific hybridembryos which abort before they reach maturity. This study explored effects ofthe three exogenous plant growth regulators 1naphthaleneacetic acid (NAA)‚ gibberellic acid (GA‚)‚ and 6-benzylaminopurine (6-BAP); sucrose; and

Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat. For example

Life is a journey……A journey of love and gain‚ hatred and pain‚ peace and bliss‚ darkness and gloom‚ a journey towards closure. It is an excursion of soul. It is an immortal game of beginnings and endings; beginnings that fade away and endings that close nearer. It is the journey on TRACKS‚ with TRACKS‚ towards TRACKS‚ and away from TRACKS; tracks that take us to fates and destinations; tracks that brew and bake our journey and disband it too; tracks that mould the living and the non-living

study revealed that Food Crops are the major crops cultivated in the study area‚ and the effects of climate change on agricultural production results to soil loss‚ plant nutrient loss‚ textural change‚ increase in pests and diseases and poor yield germination etc. This study therefore recommended that cover trees should be planted‚ which will provide shade and reduce heat‚ due to climate change and the preservation of underground water.

female egg and it occurs in the fallopian tube of the female reproductive tract. Life for a new plant begins when it germinates from the seed. Part of the maturation occurs while in the embryonic stage‚ and the remainder occurs after birth and germination. Life for an animal begins when exiting the mother’s womb or from an egg. In both cases‚ birth is experienced; however‚ with plants the process is called mitosis and with animals it is called meiosis. In plants gametes are not produced directly
