2:What is the difference between an artery and a vein?
An artery carries blood away from the heart; a vein carries blood to the heart.
An artery is responsible for carrying blood; a vein is responsible for gas exchange.
An artery is responsible for gas exchange; a vein is responsible for carrying blood.
An artery carries blood to the heart; a vein carries blood away from the heart.
3:The __________ system is made up of the nose, pharynx, trachea, lungs, bronchi, and alveoli.
circulatory
endocrine
immune
respiratory
4:Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.
What process is being described?
Breathing
Excretion
Homeostasis
Respiration
5:The __________ system is responsible for moving blood cells throughout the body.
circulatory
endocrine
immune
respiratory

Answer:
The multi store model of memory theory was first developed by Richard Atkinson and Shiffrin. There are three different memory stores in the theory: sensory memory, short term memory and also the long-term memory. They all differentiate from each other by their capacities and duration. Information is processed through our sensory memory first (what we sense, the first piece of information gathered) and is then passed onto the short term memory, where the information it has received only stays for a short amount of time, this is unless it is rehearsed continuously, then it will go to the long term memory where the information is stored and is rehearsed again and again to make sure it stays in the LTM.
The sensory memory is all of the information from your senses, it has a duration of 0-2 seconds unless you pay attention to it. Short term memory is where memory is stored for a short period unless it is rehearsed, it has a duration of 18-30 seconds and a capacity of 7+/-2 (7 items). Finally, the long-term memory is the final store of the multistore memory model, duration is infinite unless forgotten, and capacity is also unlimited / infinite. Both the STM and LTM need to be constantly rehearsed otherwise they will be forgotten; this is according to the multistore model.
A Strength of the multi store model of memory is that it is supported by research, for example, Baddeley shows that sometimes we mix up words that sound similar when we use our STM, whereas we mix up words that have similar meanings in the LTM. This is a strength because it tells us the coding in STM is acoustic and coding in LTM is semantic. Meaning they are different; this supports the view that STM and LTM are two memory stores and are separate and independent.
Another strength to the MSM is that it gives us a good understanding of the structure and process of the STM. Allowing researchers to expand on this model. This gives researchers the opportunity to do more experiments on how to improve the MSM and make it more valid. Therefore, the model is influential and gives researchers more opportunity to generate a lot more research into memory.
According to the MSM, what matters is the rehearsal and the amount of rehearsal you do. The more you rehearse the more information that will be stored into the long-term memory and remembered for a long time. But, according to Craik and Watkins, this is wrong. What actually matters is the type of rehearsal done. There are two types of rehearsal: maintenance rehearsal and elaborative rehearsal. The Maintenance Rehearsal is described in the MSM, it does not help with rehearsing in the LTM, only the STM. Elaborative rehearsal is used for the LTM, referring to when you link information to the knowledge you already have. This is a weakness because the MSM cannot explain this research.
