Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides oz

I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells. Bacteria

What makes plants grow Several people have puzzled over this question
What makes plants grow? Several people have puzzled over this question. There is no one single answer to this. Several factors contribute: Tropisms, environment, hormones, biological clocks, and even humans. We are trying to determine the effects of music on plants. It takes all these combined to have a plant that actually grows and a plant that is healthy and happy in its habitat. Hormones Hormones contribute greatly to the growth of plants. Hormones such as auxins, gibberellins, cytokinins, a

Cloning
Cloning Twenty years ago, scientists said that cloning was completely impossible. But now, the science of cloning has come to realization. Imagine meeting an exact replica of somebody. They look alike, think alike, and even have the same genetic makeup. No, this isn't an episode of Star Trek, this is reality. This is the new world of cloning, and thanks to a 7-month-old sheep named Dolly, a new science has been born. As with every new science, there are those who believe in it, and those who op

We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed omnipotent being.

Nutrition is the science that deals with food and how the body uses it. All living things need food to live. The food supplies energy, which people need to perform certain actions. Food also provides substances that the body needs to build and repair its tissues and to regulate its organs and organ systems.

Arguments for the restriction of human genetic engineering, and specifically germ-line enhancement, are reviewed. Arguments are divided into those which are fundamental matters of faith, or bio-Luddite arguments, and those which can be addressed through public policy, or gene-angst arguments. The four bio-L

Essay of Eukaryotic Organelles 10/1/96 The mitochondria has an eggshape structure. The mitochondria consists of an inner and outer membrane. The outer membrane is what shapes the organelle to its egglike shape. The inner membrane which folds inward makes a set of shelves or cristae that allow the reactions of the mitochondria to take place. The more the mitochondria makes these reactions the more the inner membrane folds. This happens because the mitochondria now has more surface area connecti

It has been cultivated for centuries mainly for the hemp fiber but also for its psychoactive and putative medical properties. There are many street names for marijuana such as pot, herb, weed, grass, Mary Jane, bud, or chronic. There are over 200 slang terms for marijuana.

Cell division is controlled by DNA, but exact copies of the DNA must be given to the daughter cells (note use of “mother” and “daughter”). Bacteria reproduce by a simple process called binary fission. They have one chromosome which is attached to the cell membrane. This chromosome replicates, then the two copies

There are three characteristics that include: exoskeletons, segmented bodies, and jointed appendages. Another reason why insects are so successful is because most insects are small and therefore have ada
