The number of individuals with each trait in a population?
What is distribution?
Scientists measured the height of the giraffes in two different populations. Which population has the largest number of tall giraffes?
What is Somalia
All of the people born and living at about the same time
What is a generation
Scientists measured the height of giraffes in two populations—one in the wild and one in a nature preserve. Which statement best describes the difference between the two populations?
The giraffes in the wild are mostly shorter than the giraffes found in the nature preserve.
A trait that makes it less-likely that an individual will survive in a specific environment.
What is a non-adaptive trait?
If their environment changes to have only long flowers, which of the following hummingbird populations will most likely survive?
The population with long beaks, and the population with both short and long beaks.
The surroundings or conditions in which a person, animal, or plant lives or operates.
What is an environment
Scientists measured the spot size of all the guppies (small fish) that lived in a river 40 years ago. They measured the spot size of the guppy population again last year. When was there more variation in the spot size of
There was the same amount of variation in spot size 40 years ago and last year.
The difference in traits between individual organisms.
What is variation?
Blue jays can have different beaks. (Thick ones to break seeds or thin ones to get into small areas). If their environment changes to have only seeds in pinecones, which blue jays populations will most likely survive?
What is thin beaks.
The area and resources used by a particular species
What does biotic mean
If their environment changes to have only long flowers, which of the following hummingbird populations will most likely survive?
Populations 2 and 3 will survive.
A trait that makes it more likely that an individual will survive in a specific environment.
What is an adaptive trait?
Scientists measured the spot size of guppies (small fish) in two different populations. Which population has more guppies with large spots?
What is Venezuela.
Non living things with in an area
What does abiotic mean
Scientists measured the spot size of all the guppies (small fish) that lived in a river 40 years ago. They measured the spot size of the guppy population again last year. When was there more variation in the spot size of
There was the same amount of variation in spot size 40 years ago and last year.
A particular section, group, or type of people or animals living in an area or country
What is a population?
There is a species of snake that can be born red or yellow and live in an environment with red and yellow sand. Which population is most likely to survive?
What is both the red an yellow snakes.
What is a cause
How did the environment change between time 1 and time 2? How did the population change?
The water became colder. Seals with thick blubber are more likely to survive, so both kinds of seals passed on the gene for thick blubber to their offspring.
