what does the zebra mussel do to affect the ecosystem
Answer:
The explanation of the type of situation would be characterized below.
Explanation:
Zebra mussels, therefore, have a direct as well as indirect (significant) impact on natural ecosystems. The much more significant impact is on the feed intake interaction including its mussel. Zebra mussels seem to be opportunistic feeders that analyze approximately one gallon of liquid or more per mussel.Will give brainliest if correct

What element is added to copper to make bronze? Why is this important for making bells?
Answer:
The correct answer is - tin.
Explanation:
Tin is the element that is mixed with copper to make bronze as bronze has many unique properties such as crisp sound quality and hardness. The hardness of the bronze allows them to make a good quality sound is come by adding tin to copper restricts the free flow of electrons of the copper atoms.
The pure metals have molecules present in an orderly manner and allow the electrons to free flow. This is why bell makers use bronze as it does not allow electrons to move freely which makes it hard and makes a good sound.
research the Greenhouse effect and how it relates to heat transfer.
Answer:
The greenhouse effect is a phenomenon of radiative transfer, the process by which the energy of light waves is exchanged in matter. Radiative transfer dictates what energy is reflected, absorbed, and emitted. The greenhouse effect: A summary of the heat transfer in the Earth's atmosphere

If the spring constant is 12.6N/m and a spring is stretched by 0.25m, how much force has been applied?
Answer:
The magnitude of the applied force is 3.15 N
Explanation:
Hooke's law states that for small deformations, the change in dimensions, 'x', of an object is directly proportional to the force, 'F', of the acting load acting that bring about the deformation
Mathematically, Hooke's Law can be expressed as follows;
F = k·x
Where;
F = The applied load
k = The force constant of the object
x = The amount of deformation of the object
The given parameters are;
The spring's force constant, k = 12.6 N/m
The amount of stretching in the spring, x = 0.25 m
Therefore, we have;
The force applied, F = k·x = 12.6 N/m × 0.25 m = 3.15 N.
how does plants react with no scratch?
Answer:
You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.
without energy it wont get energy/food so it will eventually die

Give 2 reasons why is copper used for electrial wires
Answer:
Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.

What is the purpose of a catalyst?
Answer:
option c
Explanation:
as catalyst increases the reaction while activation energy is inversely proportional to rate of reaction, so option c is correct
The purpose of a catalyst to lower the activation energy of a reaction.
What is catalyst?A type of chemical that, without becoming consumed by the process, speeding a chemical reaction or reduce the temperature as well as the pressure required to initiate one. The addition of a catalyst to speed up a reaction is known as catalysis.
What is activation energy?The bare minimum additional energy needed by a reactive molecule to transform into a product is considered as activation energy.
The purpose of a catalyst is to lower the activation energy of a reaction.
Therefore, the correct answer will be an option (C).
To know more about catalyst and activation energy.

why is CH3OH more polar than CH3CH2OH
Answer:
Explanation:
Polarity is about differencens in electronegativity. CH bonds have around the same electronegativity value so a CH bond is nonpolar. The more CH bonds there are in a molecule, the more nonpolar it is. Since CH3CH2OH has more carbon-hydrogen bonds than CH3OH, it is more nonpolar. With the same reasoning, since CH3OH has less CH bonds, it's more polar.
What are the steps to naming an ionic compound with both a polyatomic ion and transition metal.
