What does this quote mean to you?
Quote: “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is $tupid.”-Albert
Answer:
It basically means that everyone is a genius in their own way and everyone has their own skills. If you decide to judge someone on what they cannot do (eg. a fish climbing a tree) rather than what they can do, it's gonna make the person feel $tupid their entire life. Not everyone can do the same thing and not everyone has the same abilities. A fish may not be able to climb a tree, but it can swim well. Just like a bee wouldn't be able to swim, but it can fly.

What is the purpose of xylem?
Answer:
xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as treachery elements. The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
Explanation:
a cell has a 5% salt concentration is placed in a solution with a 15% salt concentration, the cell will
Answer:

2. Which type of nuclear energy is used in commercial nuclear reactors to produce electrical
energy? In two to three sentences, describe how a nuclear power plant works.
Answer:
nuclear fission
Nuclear power comes from nuclear fission
The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy
In nuclear power plants, neutrons collide with uranium atoms, splitting them. In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity
