The table below shows two conclusions about atoms based on experiments by Rutherford and Thompson Rutherford
Fire radioactive particles through thin gold foils and detect them on a
screen
Scatter radioactive particles
The nucleus is the center of the atom with electrons revolving around it in
orbits
It is a spherical object containing electrons in a massive positive charge
distribution
Thompson
Which of these statements best explains why Rutherford and Thompson visualized the atom differently?
Atoms of different elements contain different particles.
New experimental processes provide new scientific evidence.
A single model of an atom cannot be agreed upon by all scientists.
Scientists believe in proposing theories which contradict current theories.

Which of the following statements is correct in hour our immune system responds to a potential pathogen? a. the adapted immune system will call on the innate immune system to destroy the pathogen. b. b cells will start reading the antigen code immediately and call t cells to assist in destroying the pathogen. c. the skin will be the first line of defense, and then the many phagocytes in the bloodstream will attempt to consume the possible pathogen. d. the t-cells in the adapted immune systems are the first to recognize the pathogen vaccines are weakened forms of disease causing microorganisms, which are given to patients to prevent disease. after the vaccine is administered, the immune system responds by creating a(n) to recognize the a. antigen, antibody b. antibody, antigen c. antibody, antibiotic d. antibiotic, antibody
