Biology: Unit 1: Diversity Of Life Fungi Fungi: are multi-cellular heterotrophs that use external digestion‚ and often grow out of sight‚ underground → fungi have nothing in common with plants other then the fact that they are stationary‚ and grow in the ground. They are not photosynthetic‚ and they do not produce their own food. Characteristics/ Cell Structure: * Mesh like bodies‚ composed of branching networks of filaments called mycelium * Mycelium: a branched mass of hyphae

No to GMO Genetically modified foods are foods or plants that have been modified by researchers and scientists to improve the growth and development process. This idea was first introduced in 1982 and now has become widespread in use‚ especially in the US. This technology is sometimes referred to as “gene technology” or “genetic engineering” (WHO). All genetically modified foods are produced in a laboratory to “enhance its biological feature” (Godiff). This is not healthy. GM foods have the potential

Group selection describes natural selection operating between groups of organisms‚ rather than between individuals. This would produce adaptations that benefit the group‚ rather than the individual. Darwin’s theory of evolution was based upon individual selection‚ and he rejected the idea of group selection. Artificial selection is the selective breeding carried out by humans to alter a population. It is a procedure often used in agriculture: artificial selection has been used to alter the number

outright by poisoning them. Smog or particulates may cause cancer or trigger people to have asthma attacks in a lot of individuals (Consulting‚ 2005). Some ways to control air pollution‚ is taking steps to produce the presence of allergens like pollen‚ pet dander indoors. Reducing outdoor pollution is a long term effort. But overall‚ we can control some of these factors‚ like cigarette smoke‚ by not smoking indoors. We can reduce air pollution outside such as automobile emission by changing our

our environment allows us to live free of any pollutants or hazards that we might introduce into our environment. That leaves us free to try to survive in the "natural" environment which includes things like sharks‚ poisonous insects and reptiles‚ pollen‚ poisonous plants‚ viruses‚ bacteria‚ thousands of parasites‚ and other animals that compete for food and land. Protecting the environment allows future generations of humans to grow and live without having to deal with anything we’ve done to contaminate

DATING METHODS | MATERIALS | AGE LIMIT | NOTES | RADIOCARBON DATING (Is also known as C-14 Dating) | Radiocarbon dating can date organic materials.For example‚ pollen‚ bone‚ hair‚ parchment‚ wood‚ charcoal etc. | 400-50000 years old. | Principal that all living things interact constantly with the atmosphere and we absorb Carbon 14‚ however at the point of death‚ living creatures stop absorbing carbon 14‚ and the carbon 14 is frozen. This carbon decays at a known‚ constant rate. | AMS DATING

The seven processes of life The seven processes of life are the key to all living organisms: these processes consist of nutrition‚ growth‚ movement‚ respiration‚ reproduction‚ sensitivity and excretion. Although‚ they may be achieved in different ways depending on the organism. These processes happen with in both plants and animals; in each organ‚ cell and organelle. All these processes are interlinked and have a chain effect upon one another. Without one of them the others aren’t possible.

DNA- is the material found in the nucleus that contains the genetic info. 4 billion codes in length Gene- a segment of DNA that controls a certain protein production. A gene is made up of hundreds to thousands of codes. Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like‚ body function‚ body communications‚ and enzyme control) DNA screening- the process of testing individuals to determine

as pollination‚ this story is a good way of speaking openly about the subject without using technical terms. When a honey bee lands on a flower‚ their feet slip into little grooves that hold pollen sacks which they carry with them until they land upon another flower. Once landing on another flower‚ the pollen falls out of the sac enabling the plants to fertilize and sexually reproduce. For this reason‚ agriculturalists welcome the presence of honey bees among their crops. National Geographic reported
