Hello..!
There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.

Identify two characteristics shared among transverse waves, longitudinal waves, and surface waves.
Answers
Answer: For transverse waves, the waves move in perpendicular direction to the source of vibration.
For longitudinal waves, the waves move in parallel direction to the source of vibration .
They are similar within the sense that energy is transferred within the kind of waves.
Explanation:
The shared characteristics between traverse, longitudinal and surface waves include :
Traverse, longitudinal and surface waves are all mechanical waves They only transport energy without transporting matter.Mechanical waves are simply waves which requires a material medium to propagate. They include longitudinal, surface and traverse waves.
Also, all three waves transfer energy through a medium without the transfer of materials or matter in the medium.
Therefore, all three waves are mechanical waves and do not transfer matter.

Answer:
These are some steps - it usually is listed with 5 basic steps. Feedback could be the additional step.
Explanation:
Make an observation. After you make an observation ask a question. Now you will be able to form your hypothesis - what is it that you are going to test? Now, you can make a predication based on the hypothesis that you created. Make sure to test the predictions that you make. Collect data. Check to see if others have done any work like you are collecting data on. Use data to make your final decisions - based upon the hypothesis and predictions that you made. If you get confused or lost - start again and change your hypothesis. Always, always, always reflect on your results. Make sure to use DATA to back up what you find.
Why do the constellations we see change when the seasons change?
Answers
Answer:
caused by Earth's orbit around our Sun
Explanation:
:)
Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
