Answer:
A nerve cell, or neuron, is a cell that receives information from other nerve cells or are sculpted in other ways, for example, to allow one to see patterns. these “acrobats” became very good at the task over a month or so of practice.

Answer:
This question is incomplete but the completed question is below
eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?
(a)The roots change into branches, and the branches turn into roots.
(b)The roots grow toward the force of gravity, and the shoots grow away.
(c)The plant will become a smaller version of a mature plant.
(d)Roots always grow toward the dark, and shoots grow toward the light.
Two options appear to be correct here: options B and D
Explanation:
Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b
False, Xylem transports water.
Yes, sure!
1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.
2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.

3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.
4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.
