Answer: I and II
Explanation:
The gene flow will be affected because the fragmentation will make it quite cumbersome for birds in the different populations to go to each other and and be able to transfer genetic qualities which is key to genetic diversity.
The founder effect will also be affected. The founder effect is when a smaller group of a larger population are separated from the large population and form a new colony. As they are a smaller group, the genetic diversity will probably be low. With more fragmentation, the founder effect might happen a lot more as the parakeet get separated.
The answer is B New oceanic crust is formed at mid-ocean ridges, pushed away from the ridge, and destroyed at deep-sea.
Answer:
8.6 km/hr
Explanation:
It looks like there's a lot of extra information here. If the question only asks about the trip from Rohn to Nikolai, then the only information that matters is that the distance between the two is 121 km & that Seavey did it in 14 hours. Don't let the extra numbers throw you off.
As for the math behind this - km/hr is a math equation in and of itself. Any ratio like that is a simple division problem. Just plug your numbers (121 km / 14 hr) into the formula (km / hr) to get your answer!
EDIT: for future questions where they don't label it as clearly... velocity = the distance divided by the time.
