Answer;
Thomson's experiments are important because they showed that the atom is clearly composed of smaller particles.
Explanation;
J.J. Thomson used magnetic and electric fields to measure the mass-to-charge ratio of a cathode ray particle. Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. He proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
Answer:
decrease; an increase
Explanation:
Density is a physical quantity which depends upon two factors mass and volume. Density has a direct relationship with mass while an indirect relationship with volume i.e. if mass will increase then density will also increase but if volume will increase then density will decrease.
The formula for density is mentioned as under:
Density = mass/volume.
Here, in this question the reason why density of sea water will increase if temperature decreases is because a decrease in temperature will result into less movement and therefore lesser space between water molecules and lesser space indicates less volume. Since, volume and density has inverse relationship so less volume will be responsible for increase in density.
When it comes to salinity, an increase in salinity will result into the higher density of sea water. When salts dissolve into the water they add to the mass/weight of the water i.e. mass of the water increases with increase in salinity. Since, mass and density have direct relationship, an increase in salinity will increase the density of water.
This prokaryote belongs to the archaea domain, which is known for containing prokaryotes that can withstand scorching temperatures and extremely high levels of saline (ex: The Dead Sea)
