What is it called when organisms with the best traits for their environment survive and reproduce, passing that trait to the next generation.
Natural Selection
The swapping of genetic material between 2 homologous chromosomes during prophase I to provide genetic variety is called?
Crossing Over
Similar physical features in organisms that share a common ancestor, but the features serve completely different functions.

Carrying Capacity - The maximum number of individuals in a population can reach within an area. The population of organisms is hitting its limit of available resources.

A population of fish lives in a river. There are two phenotypes for scale color within the population, green and yellow. Initially, the green fish blend in the with lush plant life at the bottom of the river, while the yellow fish do not.
One day, a factory moves in and starts dumping waste into the river, killing the lush plant life that once lived on the bottom of the river. Because of this, the yellow fish now blend in better with their sandy surroundings. What is likely to happen to the allele frequency that causes the fish to have yellow scales?
It will increase/ become more common.
Look at the Powerpoint. A new predator of the grasshopper is introduced, which population will most likely increase?
Grasses
Cellular Respiration equation
6 O2 + C6H12O6 --> ATP + 6 CO2 + 6 H2O
What type of relationship is the following example? The beetle and the pseudoscorpion. The pseudoscorpion attaches themselves to the beetle, however the pseudoscorpion does not have any venom. The pseudoscorpion gains a degree of safety from the beetle and is able to move quicker around the area. The beetle hardly notices the pseudoscorpion is there and its presence not effect the beetle's life.
