The 2 types of glaciers are continental glaciers and alpine glaciers
Continental glaciers are Continental glaciers are continuous masses of ice that are much larger than alpine glaciers. Small continental glaciers are called ice fields. Big continental glaciers are called ice sheets.
Alpine glaciers are a glacier formed among summits and descending a mountain valley.
Animal cells do not have a cell wall or chloroplasts but plant cells do. This is just one example there are several ways. <span />
We can use this information to calculate the rate or speed the person was traveling at
With distance = rate * time we can figure out his rate or speed.
Plug in variables: 5 miles = 30 minutes * r
First convert 30 minutes into an hour. Which is easy. It's 1/2 an hour.
5 miles = 1/2 hour * r
Divide both sides by 1/2 hour.
5 miles / 1/2 hour = (1/2 hour * r) / 1/2 hour
10 miles per hour = r
Then switch around.
r = 10 miles per hour
I believe that a cell must use active transport to move molecules across the membrane against a gradient. Your answer should be D.
