Answer:
Mountains and Oceans
Explanation:
There are various natural barriers that prevent species from migrating such as Mountains and Oceans. If a species does not have the physical requirements to swim across an ocean or climb over a mountain it completely prevents them from passing such a barrier and moving to another geographical location to establish a new habitat. This ultimately causes them to stay in place and create a habitat island. There are many other natural barriers as well such as valleys, and rivers, waterfalls, and even weather effects such as snow habitats which some animals can't survive in.
Answer:
500 seconds.
Explanation:
it drops 2 ft/sec, so it's altitude decreases 2ft every second, so the slope is negative 2. We start out at 1000ft, so that's our y intercept and we need to set y to 0, as that's the altitude when the bird lands. So in form
y = mx + b, we plug in our values:
0 = -2x + 1000
0 + 2x = -2x + 2x + 1000
2x = 1000
x = 500
54289 = 233^2
You know the last digit of the squared number is 3 or 7, so just try numbers ending with those from 220 to 250
