Evodots
A condition or a force (predation, temperature extremes, etc.) that eliminates individuals from a population.
Selective pressure
T or F. The same mutation could be advantageous in one environment and be a disadvantage in another.
True.
It would be a disadvantage to be a white mouse on the lava flows, or a black mouse on the white sand.
Individuals cannot do this. Only populations
Adapt
The potential of species to reproduce, given optimal conditions is called...
Biotic Potential
An organism gets a new gene by inheriting it or...
mutating (having a mutation)
When a certian amount of genes changes in a population it is said that this has happened.
Evolution
____ is the genetic change in a population
Evolution
There are more offspring born than can survive. There is variation in every population. The ones that survive are the ones with a genetic advantage in that environment.Those that survive to pass on their advantageous genes to the next generation do so because of the process of....
natural selection
A wildfire puts a ____ ____ on an area's population of deer (vocab word(s))
selective pressure
What happened to the Evodot population when all the dots were the same size/color
You should have seen that more made it through your "eating" to the next generation. This is the "herd mentality"
The mechanism that made the pocket mice evolve (vocab word(s))
natural selection or selective pressure
The number of litters per year, the number of reproductive years, the number of females, and this or multiplied to get a biotic potential
number of offspring in a litter.
In your Evodots lab, Your bar graph showed the distribution of dots from the tiny blue dots, the middle teal and light green to the large yellow dots. What shape was the graph for most of your activities?
It should have been a bell curve (small at the ends with a bulge in the middle) meaning that the dots at the extremes are rarer
Cherry tomatoes make a lot of seeds because the more seeds in a fruit, the more likely that one will be successful to grow up to reproduce. True or false
True
Sarah moved to an apartment in a big city. She hears cars and sirens all the time. She will have to adapt to the level of noise. True or False
False. Adapting (scientifically) is a genetic change. She will have to "get use to" the noise or get noise cancelling headphones
