<span>Controlled variable is a variable that was made constant in the research. That was because the controlled variables can influence the dependent or independent variable. If the variables is not made constant, it can alter the research result and made it invalid.

In this case, </span>the caffeine and alcohol intake might alter the physical activity or the blood glucose so it should be controlled.

CRITICAL AND CLINICAL THINKING Exercise 7 Clinical Thinking Challenge Support each of following correct statements with appropri
cestrela7 [59]

We support each of the following correct statements with appropriate justification, indicating why or how each statement is correct.

<h3>3. A radiograph of a horse's frontal fetlock joint is called a dorsopalmar (PD) view.</h3>

Dorsopalmar (PD) view The horse's frontal fetlock joint demonstrates dislocation of the antebrachiocarpal joint with soft tissue swelling around the carpal joint

<h3>5. When performing surgery on the digestive system, we must ensure that the suture is well closed. </h3>

Yes. Endoscopic suturing is a procedure performed 100% by endoscopy, a procedure that inserts a flexible tube through the patient's oral cavity and reaches the structures of the digestive system. It is a non-invasive, safe process that does not require any cutting.

<h3>6. Oblique positions are sometimes used in radiographs.</h3>

Yes. Right and Left Anterior Oblique Positions (RAO and LAO) These terms refer to oblique positions in which the right or left anterior side of the body is close to the RI, and can be in an upright or recumbent position.

Which of these organs is found in the excretory system?
Paraphin [41]

The urinary system is the main excretory system of the body after the gastrointestinal tract (large intestine) and lungs, In these questions it is necessary to prioritize the urinary tract.

The right answer is D. Bladder

The bladder belongs to the urinary excretory system.

The bladder receives the urine produced by the kidneys via the ureter and has the function of storing it before its elimination during urination through the urethra. The muscles surrounding the bladder help to prevent urine reflux to the ureter.


The right answer is C. Kidneys

The main purpose of the renal excretory system is to eliminate nitrogenous wastes while maintaining homeostasis, all through the formation of urine.

The kidney has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon (triangle based on the renal hilum) origin of the ureter. We speak of pyelo-ureteral junction. Each kidney contains about 1 million nephron.

What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP
Nady [450]

The given question is incomplete, the complete question is:

During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions. Condition Rate of carbon dioxide produced (mL/min) Germinating peas, 10ºC 0.01 Germinating peas, 20ºC 0.02 What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production. Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production. Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC. The rate of cellular respiration cannot be measured without knowing the rate of ATP production.

Answer:

The correct statement is that at 20 degree C, the germinating peas exhibits a higher rate of cellular respiration in comparison to the germinating peas at 10 degree C.

Explanation:

The process of respiration results in the production of carbon dioxide, respiration refers to a chemical reaction that generates water, carbon dioxide, and energy by undergoing oxidation of the glucose molecules. This phenomenon plays an essential role in the life of the organisms for obtaining energy from the food they consume to perform daily activities.  

From the question, it is evident that the peas, which were germinating at 20 degrees C exhibit a higher rate of cellular respiration as they are generating 0.02 milliliters of carbon dioxide in a minute, while on the other hand, the germinating peas at 10 degrees C are giving rise to 0.01 milliliters of carbon dioxide in a minute.
