Pretend you have 2 populations of narwhals. One population (A) has a higher allele frequency for long horns, while the other population (B) has a higher allele frequency for short horns. A small subgroup of population A migrates into population B, causing changes in allele frequency. What is taking place? - Gene flow Pretend you have a tiny island of unicorns in the middle of the Atlantic ocean, thousands of miles away from other landmasses. Suppose that a brutal hurricane rages through...

A non competitive inhibitor decreases the rate of an enzyme reaction by... - Changing the shape of the enzymes active site Feedback inhibition - end product of a metabolic pathway inhibits an earlier step in the pathway A Molecule loses a hydrogen because of a redox reaction has been... - Oxidized End products of glycolysis - ATP, NADH, and pyruvate Glycolysis takes place in what part of a eukaryotic cells? - Cytosol Electron transport chain involves... - the extraction of e...

Light Reactions - when light energy is captured in thylakoid membrane, during these reactions oxygen is released, NADPH produced from NADP+, ATP is produced. How are the light reactions coupled to the Calvin cycle? - Light reactions are coupled with the calvin cycle because light reactions are the photo part and the calvin cycle is the synthesis part. Calvin cycle uses NADPH and ATP to breakdown CO2. Calvin Cycle - When CO2 is "fixed" and reduced to sugars in the stroma, forms a su...

The Kaibab Squirrel arose from a common ancestor, but have been separated by the Grand Canyon. What type of speciation event allowed the development of these two species? A) Divergent habitat speciation B) Sexual speciation C) Allopatric speciation D) Sympatric speciation - Allopatric speciation House finches were found only in western North America until 1939, when a few individuals were released in New York City. These individuals established a breeding population and gradually expa...

What is the structure and function of the Golgi apparatus? Where do proteins go from the Golgi? - stacks of flattened membrane sacs; ships proteins off to the plasma membrane How are cell contents moved from one location to another (i.e. from ER to Golgi)? - Via Vesicles; vesicles can bud off one membrane and fuse with another->contents transported What is the function of lysosomes and vacuoles? - Lysosomes are the digestive Enzyme Vesicles;digestion of food particles and damage...

How do enzymes speed up chemical reactions in cells? - Enzymes lower the activation energy barrier of reactions. What is the active site of an enzyme? - The place on the enzyme where the substrate binds Some bacteria are metabolically active in hot springs because: - Their enzymes have high optimal temperatures. HIV is the virus that causes AIDS. In the mid-1990s, researchers discovered an enzyme in HIV called protease. Once the enzyme's structure was known, researchers began lo...

In cats, black fur color is caused by an X-linked allele; the other allele at this locus causes orange fur color. The heterozygote is tortoiseshell. What kinds of offspring would you expect from the cross of an orange female and a black male? A) Orange females; black males B) Tortoiseshell females; orange males C) Tortoiseshell females; black males D) Black females; orange males - Tortoiseshell females; orange males Kirsten suffers from colorblindness, a recessive X-linked disorder. S...

Wildlife resources are a public property - Which of the following principles was influenced by the Public Trust Doctrine established in 1842? True - Under the pillar which states markets for game are eliminated, exceptions can be made for some fur-bearing species. marshes - dominated by emergent vegatation fens - have grasses and mineral rich water swamps - dominated by trees bogs - accumulates dead plant material Secondary succession - Secondary succession Behavior modif...
