Answer:
2. have no negative particle
Explanation:
Helium atoms contains 2 neutrons and 2 protons (or 2 electrons). Thus, it has a mass number of 4 and atomic number of 2.
Alpha particles are heavy and positively charged, which make them to be deflected in a magnetic or electric charge. So, the helium atoms used as alpha particles for the gold foil experiment must have no negative particle.
Answer: Condensation
Water vapor is water in a gaseous state. Transformation of water into gaseous state
(water vapor) is called evaporation. Transformation of the water vapor into dew
which Michael observed in the early morning is called condensation.
Dew<span> is water droplets
that appears on exposed objects like
leaves in the morning or evening due to condensation</span>
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
