Steps of global warming

• CO2 released and solar radiation is reflected causing warming

• solar radiation absorbed-->combustion-->CO2 causes increased warming

• combustion-->CO2 added to ozone-->solar radiation absorbed and reflected

• Solar radiation is absorbed by ozone causing warming

What lowers activation energy to control the rate of a reaction

• DNA --> nucleic acids --> nucleotides

• polysaccharides --> carbohydrates --> simple sugars

• fats -->lipids --> amino acids

• enzymes --> proteins --> amino acids

pesticide resistance is....

• when pests are sprayed with a pesticide, survive and reproduce offspring that are also immune to the pesticide

• when antibiotics are not taken in the manner they are supposed to be

• when a pest is separated from a group and cannot reproduce

• when nature selects those individuals that produce only proteins

Antibiotic resistance occurs when

• when nature selects only those bacteria that can make proteins

• when pests survive being sprayed with a pesticide

• antibiotics are not taken the way they are prescribed and the bacteria survives and is immune to that antibiotic

• When a virus cannot be killed by an antibiotic

natural selection means

• nature selects which organisms live or die according the adaptations or genetic combinations they have

• some animals live because of their behavior

• some organisms are separated and become different

• some organisms cannot reproduce

Replication occurs

• in the cytoplasm

• in the mitochondria

• at the ribosome

• in the nucleus

replication results in

• a protein

• 2 strands of DNA

• a messenger RNA

• 2 identical strands of DNA; both having 1 old and 1 new strand

What has to happen before mitosis or meiosis can happen?

• replication

• transcription

• translation

• protein synthesis

the separation of a species by something physical like a lake or road is

• isolation

• pre-zygotic reproductive isolation

• post-zygotic reproduction isolation

• geographic isolation
