Roger is at a wedding reception where he has been introduced to over 50 guests whom he has never met. He would like to remember as many names as possible. Describe the role that sensory storage, short term memory and long term memory play for roger in this situation.

Answers

The  ability of the brain to acquire information, feelings, and  processed, keep, and recollect this for the subject is called memory.

The threes stages of memory are

  • sensory storage or memory
  • short term memory and
  • long term memory.

The ability of Roger to  keep memory of the names with these three stages, depends on how pays attention and his ability  to process information.

The sensory storage depends on the five sense to send  information to his brain. Thus, Roger needs to pay attention to the faces,(iconic memory) voices (echoic memory),  feel or touch (Haptic Memory)  and (Smell) aroma of perfumes when been introduced to the guest.

 These information are retains for few seconds after the guest( the sensation has gone).Thus with this ,he sees every guest as collective set of people without  and not as individual. For his brain to process the information as individual  he needs to network with the Short memory.

The short memory  is the type that retain the information( the names ,voices and touches) of the guests he was introduced to at that present moment. He needs to pay attention and try to retain these sensation to prevent them from been forgotten. These  sensations are  retain  tentatively until the  information is processed. It is these processed information that are stored  by his brain ,and not the sensory signals like in the sensory.

In order for the processed or interpreted information to be stored and used for longer time, and recalled when needed, these are transferred to the long term memory. This is subdivided into  two types; explicit  and implicit memory.

He will makes use of the explicit memory because the stored names can  be recollected consciously after storage when the 3 types of memories are merged. Unlike the  implicit that can not be access consciously.

With the capture of the image of the guest with sensory memory, temporary store  the processed names  with short term and   stored this  for future, Roger should  be able to remember these names.

Answer:

In this situation, the role of sensory storage would be-

as he enters at reception the smalls, images, would be sensed by him and make its burn the memories in his brain.

Short-Term memory helps in make him remember by the names associated with the small gesture, movement, mannerisms made by them. For example, sam stutters can be remembered as stutter Sam.

Long-Term memory helps in building memory by long haul with help of scenery by relating individuals he already know before the reception and whenever see them mind reminds the name.

) You treat some cells with a proteolytic enzyme that is too large to penetrate the cell membrane (Set 1). Another group of cells is made permeable before treatment with the enzyme (Set 2). A third set of cells was not treated with the enzyme at all (controls). Proteins are then extracted from the three different sets of cells and applied to an SDS-PAGE gel. Protein W migrates to the same distance on a gel of proteins from Set 1 and Set 2; Protein W migrates a shorter distance on gels of proteins extracted from the control group than on gels of proteins extracted from Set 1 and Set 2 treated cells. Protein X migrates to the same distance on a gel of proteins from control cells and the gels of the proteins from Set 1 and Set 2. Protein Y migrates a longer distance when extracted from Set 1 cells than does protein Y in the controls; Protein Y moves an even larger distance in the gel of the extracts from Set 2. Protein Z migrates the same distance on gels of proteins from the controls and the proteins extracted from Set 1, but it migrates a longer distance in extracts from Set 2 cells. Which protein is exposed only on the exterior of the cell?

Answers

Answer:

Proten W

Explanation:

SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).

When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).

Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.

Answers

For a molecule to be considered organic elements must be present in  Carbon and hydrogen. The answer to your question would be letter C. These are use in order to create an element which is further used all living organisms in living.
for a molecule to be organic, it has to contain a backbone of carbon and some hydrogen so the answer would be C.

Bone does not amplify sound during speaking is _____________________

Answers

Answer:

Bone is a solid tissue, which resists a high impact of forces in its major axis.

The function of this fabric is not to transmit sounds, since it does not provide the elasticity, and the necessary elongation that is needed to generate the rope effect as in the case of muzzle cords.

Explanation:

The more rigid and less elastic the fabric is, the less sound it will transmit.

Sound strings, or mouth strings, are those that tighten, are flexible and resonate with different vibrations, in the case of bone tissue, sound vibrations are not influenced in their conformation because they do not have the ability to transmit them. .

The bone tissue, transmits impact forces or high newton levels, does not fulfill the function of transmitting vibrations and emitting sounds in terms of this type of vibrations and their frequencies.
