Answer:
Stimulus discrimination
Explanation:
Stimulus discrimination is referred to the ability for an individual or animal, as the case may be, to discriminate between two different stimuli and react differently. From the question, Micah was frightened by a little dog when he was 2 years old. The stimulus in this example will be Micah's fear of little dogs. The question clearly stated that Micah does not fear large dogs, which means that he reacts differently to a different stimulus (large dogs). If Micah responds with fear when he sees large dogs, then this phenomenon will be known as Stimulus generalization. The difference between stimulus discrimination and stimulus generalization is that while discrimination entail differing response to different stimuli, generalization entails same response to different stimuli.
Answer:
A) Listeria monocytogenes
Explanation:
Listeria monocytogenes
It is the specific pathogen bacteria which causes the inefection , Listeriosis .
It is a anaerobic bacteria , hence can survive even in the absence of oxygen . It has the capability to grow and reproduce inside its host cell .
It is the most virulent foodborne pathogens .
The source by which this bacteria can spread is food .
Oddly enough, type O blood in the U.S. is not by itself the rarest blood type. Actually O+ is one of the most common. But because O is the recessive of the A-B-O gene group, and also Rh- is recessive in it's gene, the combination makes it extremely rare. Roughly 85% if people have the Rh+ allele, and roughly 1/3 people are O, but those are only O+.
The rarest is actually AB-, because 3% or less are this type. O- people are around 5% of population.
However because O- blood is the "universal donor" (will not cause immune reactions with any other blood type when transfused in) for hospitals and blood banks, it is always in short supply.
