Integrated Life Science Study Guide

• The scientific method- A continuous process use to collect observationsk form amd test hypotheses, make predictions, and identify patterns in the physical world.
• Biodiversity- the number of different species that coexist at a given place
• Dimitri Mendelev- Russian Chemist; created the Period Table of the Elements; 1st 1800s to arrange elements in such a way that the showed something about it properties. Elements made of atoms-Iron, Helium, Hydrogen

Creationism or creation science is the belief of the Judeo-Christians (Bible); Genesis; 2000+ yrs. The Earth is between 5-7000 yrs old. It’s the belief that it was created in 7 days. Science of Creation (most scientists believe) believes the universe is approx. 15 Billion yrs old. Earth-is about 4. 5 billio9n yrs old. No beginning and no end to this universe.

• Stem cells- embryonic cells that can become any cell in a living organism. Source; ambilical cord Adult stem cell-restricting-almost useless to work with; medical science impeded by someones belief system
• Work- force exerted over a distance

Power- work divided by time; how fast you do work. Power =work/time Energy= the ability to do work; we get energy from food; converts to calorie-> glucose; cell->work; plants also use glucose to live 2 types of energy- Kinetic-energy of motion Potential- stored (fat) Force-a push or pull from kinectic energy; gravity energy-> glucose

Trophic levels

1. Omnivores-eat both plants and animals
2. Carnivores-eat meat. ex. Lions, tigers,
3. Herbivores-eat plants, ex. Cows, horses
4. Plants- glucose
5. Decomposers-bacteria; worms, fungi, provide food to make soil rich

Acid rain- nitrogen, sulfur, ad carbon; coal + oil fired; electricity; generating plants; polluntants mix with rain; forms sulphuric acid; nitric acid; and carbonic acid- kills plants & trees; destroys auto paint, etc.

Photovoltaic cells- a device that converts sunlight (photons) into direct electric current

Short Answer

Global Warming

• CONS – temperature increasing; flooding; sea level rising; quit burning fossil fuels
• PROS – temp increasing during growing season which is what’s necessary
• Ozone layer is 20 miles or more up. It protects us from UVA and UVB rays.

Questions to ask when confronted with other kinds of psuedosciences

• Are the “facts” true as stated?
• Is there an alternative explanation?
• Is the claim falsifiable?
• Have the claims been rigorously tested?
• Do the claims require unreasonable changes in accepted ideas?

Peer review is a system by which the editor of a scientific journal submits manuscripts considered for publication to a panel of knowledgeable scientis wh, in conidence, evaluate the manuscript for mistakes, misstatements, or shoddy procedures.

Following the review, if the manuscript is to be published, it is returned to the author with a list of modiciations and corrections to be completed. Arrow of Time is The uniform and unique direction associated with the apparent inevitable flow of time into the future.  The 3 major polluntants that make up urban pollution are nitrogen oxides, sulfur compounds, and hydrocarbons.
