What are the changes from the Baddeley 2000 model to the new Baddeley 2012 model?
Answers
Answer:
The Baddeley 2000 model proposed that working memory consisted of three components: the phonological loop, the visuospatial sketchpad, and the central executive. In this model, the central executive was considered a general-purpose attentional control system that could direct attention to different tasks and coordinate the other two components.
The Baddeley 2012 model built upon the previous model and included a fourth component, the episodic buffer. The episodic buffer is responsible for integrating information from the phonological loop, the visuospatial sketchpad, and long-term memory into a single, coherent representation that can be used for higher-level cognitive processes such as reasoning and problem-solving.
Additionally, the central executive was further elaborated in the Baddeley 2012 model to include two distinct attentional control systems: the supervisory attentional system and the attentional control network. The supervisory attentional system is responsible for controlling and coordinating the other three components of working memory, while the attentional control network is involved in goal-directed attentional control and conflict resolution.
Overall, the Baddeley 2012 model expands upon the Baddeley 2000 model by including a new component (the episodic buffer) and elaborating on the functions of the central executive.
In 2000, Baddeley proposed a model of memory that included three components: the phonological loop, visuospatial sketchpad, and central executive. However, in 2012, Baddeley updated his model to include two additional components: the episodic buffer and the fourth component was added to explain interactions between the other components.
This new model improves our understanding of how we store and retrieve memories. The episodic buffer acts as a temporary storage unit for information from all the other components before it is transferred to long-term memory. This addition helps us understand how we can remember complex events with multiple sensory inputs.
Additionally, the fourth component serves as a way to integrate information from the other components to help guide decision-making and problem-solving. By updating this model, Baddeley has provided a more comprehensive framework for studying human memory that allows researchers to better investigate how different cognitive processes interact.
.Which of the following substances is involved in the destruction of ingested pathogens?
A lymphatic fluid
B stomach acid
C. Bicarbonate
D. lipase
Answers
Stomach acid is involved in the destruction of ingested pathogens. Stomach acid, specifically hydrochloric acid (HCl), helps to break down food and eliminate harmful microorganisms that may be present, thus playing a vital role in protecting our body from infections.
The correct answer is B.
The substance that is involved in the destruction of ingested pathogens is stomach acid (B). This acid is a part of the digestive system and helps break down food as well as kill any harmful bacteria or pathogens that may be present in the ingested material. The acid is produced by cells in the lining of the stomach and has a pH of around 2, making it highly acidic and effective at destroying pathogens.
While lymphatic fluid, bicarbonate, and lipase are all important components of the digestive system, they do not have the same antimicrobial properties as stomach acid. In summary, the long answer to this question is that stomach acid is the substance involved in the destruction of ingested pathogens.

1
"A high-protein intake ensures an adequate daily supply of amino acids to compensate for losses."
2
"Essential and nonessential amino acids are necessary in the diet to supply materials for tissue protein synthesis."
3
"This diet supplies only essential amino acids, reducing the amount of metabolic waste products, thus decreasing stress on the kidneys."
4
"Currently, your body is unable to synthesize amino acids, so the nitrogen for amino acid synthesis must come from the dietary protein."
Answers
The nurse would include the following information in response to a client's questioning a protein-restricted dietary change required for his or her acute kidney injury:This diet supplies only essential amino acids, reducing the amount of metabolic waste products, thus decreasing stress on the kidneys." Option C.
The above statement is an appropriate answer to this question since protein is made up of building blocks called amino acids. The nitrogen in amino acids must come from dietary protein since the body cannot synthesize amino acids. It is recommended that patients with acute kidney injury consume only essential amino acids to minimize the amount of metabolic waste products in the blood.
This will lower the strain on the kidneys, allowing them to heal properly. A high-protein intake ensures an adequate daily supply of amino acids to compensate for losses. Essential and nonessential amino acids are necessary in the diet to supply materials for tissue protein synthesis. However, in the case of kidney injury, it is recommended that only essential amino acids are consumed.
Protein is an important nutrient that our body requires for many processes, including building and repairing tissue, producing enzymes and hormones, and helping with immune function. Nonetheless, a protein-restricted diet may be necessary for individuals with kidney injury to promote kidney recovery. Option C.

You've always wondered how much one of your friends weighs and devise a scheme to measure his weight secretly. You have him sit in a tubular steel chair. This popular style of chair consists of a single steel tube that's bent into a frame and that supports a seat bottom and a back. The empty chair weighs 10 pounds and is 30 inches tall. The frame acts as a spring and bends downward slightly when the chair is occupied. When you sit properly in the chair yourself, it bends downward 1 inch. When your friend sits properly in the chair, it bends downward 2 inches. From that observation, you know that your friend weighs about:________.(A) 300 pounds.(B) twice as much as you do.(C) four times as much as you do.(D) 150 pounds.
Answers
Based on the observation that the chair bends downward 2 inches when your friend sits properly in it, while it bends downward 1 inch when you sit properly in it, it can be concluded that your friend weighs four times as much as you do. Therefore, the correct answer is (C) four times as much as you do.
The bending of the chair frame can be attributed to the weight applied to it. The difference in bending between you and your friend provides a ratio that can be used to determine the weight comparison. Let's break down the steps:
1. Observation: When you sit properly in the chair, it bends downward 1 inch. When your friend sits properly in the chair, it bends downward 2 inches.
2. Weight-to-Bending Ratio: The bending of the chair frame is proportional to the weight applied to it. Since the bending for your friend is twice that of yours, it suggests that their weight is also twice as much as yours.
3. Weight Comparison: Given that the empty chair weighs 10 pounds, your weight can be estimated by subtracting the weight of the empty chair from the weight required for it to bend downward 1 inch. Similarly, your friend's weight can be estimated by subtracting the weight of the empty chair from the weight required for it to bend downward by 2 inches.
4. Conclusion: Since the bending for your friend is four times that of yours (2 inches compared to 1 inch), it indicates that your friend weighs four times as much as you do.
Therefore, the correct answer is (C) four times as much as you do.

Creatine is a supplement used by athletes to help increase strength, power, and muscle mass. Creatine is also known as what?.
Answers
Creatine is a supplement used by athletes to help increase strength, power, and muscle mass. Creatine is also known as creatine monohydrate.
Creatine is a naturally occurring non-protein substance that serves as the main component of phosphocreatine, which is used by cells to renew ATP. Skeletal muscle makes up 95% of the body's total creatine and phosphocreatine reserves, with the remaining portion being dispersed throughout the blood, brain, testes, and other tissues.
The most popular of them is creatine monohydrate, a dietary supplement that improves muscle function during brief, intense bouts of resistance training. According to studies, using these supplements helps athletes who are doing strength training, particularly when they are weightlifting and cycling. The standard, original form of creatine that people have been utilising for decades is called creatine monohydrate. Out of all the creatine products, it is still the one that sells the most. When looking for a creatine supplement, purity is crucial since the purer the product, the more effective it will be.
