<u>Answer</u>:
Cameron has been very stressed during harvest season while working on farm equipment in the evenings and harvesting the crops during the day. He comes down with the flu the day after his last field is harvested. The reason for his illness is likely that Cameron’s stress hormones suppressed the activity of Lymphocytes.
<u>Explanation</u>:
Immune system is the collection of billion number of cells that travel through our bloodstream. They defend our body against bacteria and viruses. White blood cells are the main immune cells in our body.
When a person gets stressed, the immune system's ability to fight gets reduced. The stress hormone “corticosteroid” suppresses the efficiency of the 'immune system' by reducing the number of "Lymphocytes". Lymphocytes are of two types:
a. "B cells" which produce antibodies and are released in the "fluid" surrounding the body cells.
b. "T cells" which gets locked to the 'infected' cell and destroy it.
Answer:a. Most manipulations are straightforward. False.
b. Staged manipulations are designed to get participants involved in the situation and to make them think that it is a real experience. True
c. A staged experiment may be difficult to replicate by other researchers. True.
d. Straightforward manipulations are often difficult to interpret. False
Explanation:straightforward manipulation
manipulate variables with instructions and stimulus presentations.(verbal, written, video, computer)
staged manipulation
staged events that occur during the experiment in order to manipulate the independent variable successfully.
The correct answer is letter D.
Preparedness if often linked to the concept of learned helplessness. This is the common adaptive behavior of humans or organisms to certain experiences that have happened before. Usually it is a repeated painful stimuli that an organism has endured many times, which then when presented again, enables the organism to escape or avoid the situation. In essence, the stimulus is familiar, hence, the organism learns how to prepare for the outcome or consequence.
Answer: B) sympathetic nervous system
Explanation: The sympathetic nervous system is a section of the automatic nervous system in the body that reacts to stressful or dangerous situations by stimulating the fight-flight-or-freeze response. This causes the body's alertness to increase as well as increase in the rate of heartbeat.
Some of the visible symptoms includes Hypertension, Agitation. Muscle rigidity, Heavy breathing etc.
The fact that the individual didn't study for the exam he or she is writing puts the individual in a stressful position, that is why his or her sympathetic nervous system kicked in to stimulate the body's fight-flight-or-freeze response, causing the individual's rate of heart beat to increase as well as having dry mouth.
Answer:
i do not normally hear the fireworks all the time before that day 4th, but with each passing day, i start to hear them via a process usually called reverse habituation or i still do not hear the firework all before on the 4th due to the fact that i became habituated to fireworks over new year celebration
Explanation:
Habituation can simply be defined a a process of psychological learning. it involves a process whereby there is a decline/decrease in response to a stimulus after being exposed to it constantly. this habituation believes holds that human/animals may learn to ignore a stimulus due to consistent exposure to it.
