Selective 5-HT3 receptor antagonist
Answer: Option E.
All of the above.
Explanation:
Streptococci pyogenes is a disease caused by streptococci bacteria. These bacteria are gram positive ,non sporeforming and non motile.
The virulence factors are substance produced by bacteria to ensure their effective attack.
The virulence factors of S. Pyogenes are;
Spiky M proteins and lipoteichoic acids which they use as attachment to host organisms.
Hyaluronic capsule which the use to slow or inhibit phagocytosis.
Polysaccharide cell wall which causes the rash of scarlet fever.
Correct answer: B). Static information that does not change
Pseudoscience refers to the belief that is falsely based on the science. It is characterized by the contradictory claims. It does not have a valid and scientific proof.
It contains theories, beliefs or the practice that has been considered scientific but do not have a scientific basis of fact. They have a lack of evidence to support the hypothesis or the theory.
Astronomers use an effect called parallax to measure distances or nearby stars.
The correct answer is to Represent the locations of subatomic particles in different atomic theories.
Explanation:
Atoms, which are the basic unit of matter in the universe are composed of subatomic particles (protons, neutrons, electrons). Moreover, during history atoms have been represented through different models that differ in their general structure as well as the location of sub particles.
This can be seen in the image presented because Thompson's model purposes electrons, which are represented by circles with the negative sign, are distributed inside a positively charged substance. On the other hand, Bohr's model proposes protons are in the center and electrons orbit around it, which shows different locations of sub-particles.
