Answer:
[tex]\dfrac{dy}{dx}=\dfrac{4}{25}[/tex]
Explanation:
The given expression is :
[tex]y=\dfrac{(x-1)}{(x+3)}[/tex]
We need to find dy/dx at x = 2
[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]
Put x = 2 in above expression
[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]
Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

The opening and closing of _____________in your heart create the lub-dub sound and prevent the backflow of blood.
What goes in the blank?
Answer:
Heart valves or the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole and the closure of the aortic valve and pulmonary valve at the end of ventricular systole.
Explanation:
The heart tone “lub,” or S1, is caused by the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole.
The heart tone “dub,” or S2 ( a combination of A2 and P2), is caused by the closure of the aortic valve and pulmonary valve at the end of ventricular systole.

A team from New York Presbyterian hospital is conducting a study about a recent increase in cases involving both excess sweating and kidney stones. What would the team need before it draws a conclusion about the cases?
A. medications that are specifically designed to treat the sickness
B. machines that are built to process blood and reduce symptoms until patients are healthy again
C. data that profile the various patients who report these symptoms
D. proof that the excess sweating is related to the excessive kidney stones
Answer:
C the data the profile symptoms
Explanation:
The team that required prior to drawing the conclusion related to the case should be option c. where the profile shows the symptoms of various patients.
Reasons for excess sweating and kidney stones:The main reason of excessive sweating is the dehydration that means we are not drinking sufficient water due to which the risk of the kidney stones should be increased.
If the protein diet is high, or there is high salt intake, or high sugar intake due to this also the stones chances are high.
Therefore, the option c is correct.

An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function ?
Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
Oligosaccharides are a type of carbohydrates that contain the combination of a few monosaccharides. The are also found as part of the components of the membrane.
If an animal cell lacks this type of carbohydrates (oligosaccharides), the function impaired would be the cell-cell communication function.
Oligosaccharides performs various functions as part of the component of the plasma membrane. It functions in cell to cell recognition and binding and communication. They usually contain 3-10 sugar units (monosaccharides).Learn more: https://brainly.com/question/22301340

When practicing deep breathing, it is best to repeat the steps for minutes to start and then increase the time as needed.
Answer:
10- 15
Explanation:
When practicing deep breathing, it is best to repeat the steps for minutes to start and then increase the time as 10 to 15 minutes.
What is deep breathing?
Deep breathing is also called diaphragmatic breathing, abdominal breathing, abdominal breathing, and step breathing. As you take a deep breath, the air entering through your nose fills your lungs completely and lifts your lower abdomen.
Deep breathing seems unnatural to many of us. There are multiple reasons for this. For one thing, body image in our culture negatively affects breathing. Women (and men) tend to pull their abs together because flat bellies are considered attractive. This impedes deep breathing and gradually causes shallow "chest breathing" to appear normal, increasing tension and anxiety.
Shallow breathing limits the range of motion of the diaphragm. The lowest part of the lungs does not get enough oxygenated air. This can make you feel short of breath and anxious.
Deep abdominal breathing promotes complete oxygen exchange. That is, the beneficial exchange of incoming oxygen for outgoing carbon dioxide. Not surprisingly, it can slow the heart rate and lower or stabilize blood pressure.
Therefore, When practicing deep breathing, it is best to repeat the steps for minutes to start and then increase the time as 10 to 15 minutes.

What is Anaerobic respiration?
Answer:
"Anaerobic respiration is the process of creating energy without the presence of oxygen. Sometimes the body can't supply the muscles with the oxygen it needs to create energy – such as in a sprinting situation."
I hope this helped!
Answer:
The release of a relatively small amount of energy by the breakdown of food substances in the absence of oxygen. Glucose is broken down to release energy in the absence of oxygen, forming lactic acid in muscle tissue, or alcohol plus carbon dioxide in yeast and plants.
