Answer:
A selective pressure is any reason for organisms with certain phenotypes to have either a survival benefit or disadvantage.
Explanation:
Answer:
N = 187.55
Explanation:
Here you just need to replace the terms and clear the equation.
You already know that,
- First capture: 25 prairie dogs.
- First marked animals: 25 (the whole first capture)
You let these animals leave and then you made another capture.
- Second capture: 135 prairie dogs
- Already Marked animals: 18 (these 18 dogs were caught in the first capture and marked before releasing them)
To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.
Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch
- Number of individual marked in first catch = 25 dogs
- Total population size, N = this is what we want to know
- Number of individual marked in 2nd catch = 18 dogs
- Total number of 2nd catch = 135 dogs
So now, we need to replace terms
25 / N = 18 / 135
25 / N = 0.1333
N = 25 / 0.1333
N = 187.55
Science and technology have influenced everyday life for thousands of years. If it hadn't we would still be living in caves and struggling to stay alive. Everything you see around you is a form of technology. Science itself can be considered a form of technology because it has helped us advance as humans and become more able to overcome disease and predators. Most humans today wake up and are subjected to technology's control because we've fed into it so much that it would extremely hard, if not impossible, for us to survive without it.
Answer:
A
Explanation:
because cell theory states that living things are composed of one or more cells, that the cells is the basic unit of life, and that cells arise from existing cells.
