Answer:
Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis

Percentage of calories = ?
Fat = 12 grams
Total calories = 300
1 gram fat = 9 calories
to calculate calories convert gram into calories and then divide by total calories.
No. of calories = (12 x 9) / (300) = 0.36
So, percentage of calories = 0.36 x 100 = 36%
I think your answer should be B. an organism. Hope this helps. =^-^=
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
