<span>Pteridophytes (ferns) have true roots and vascular tissue that allows water to move farther
through the plant so that they don't depend on absorption of water held
on the plant as a mass of moss plants would.
Hope this helps!

Answer:
time (t) = 2.69 sec
Explanation:
Given that;
The final top speed of 3.96 m/s ( final velocity V) = 3.96 m/s .
The initial speed is 0; &
The acceleration (a) = 1.47 m/s²
We can determine how much time does it take the snake to reach its top speed by using the equation of motion;
V = U +at
3.96 = 0 + (1.47×t)
3.96 = 1.47t
t = 
time (t) = 2.69 sec
∴ It took the snake 2.69 sec to reach the its top speed.
The Earth's mantle is the layer of rock just below the Earth's crust. Just under the crust, it is solid. It is very hot, and the other part of the mantle is soft, kind of like melted candy.
The Earth's mantle is rock-hard but it actually flows around the outer core, moving about as slowly as your fingernails grow. The mantle tends to be 2,900 kilometers thick, and makes up 84% of Earth's total volume.
