What would happen if you were given pure water in an IV?

Answers

The question is what would happen if you are given pure water in an IV. The answer is, the pure water will disrupt the osmotic balance of the body. Saline solutions are usually used in IV, this is because, there is a need to maintaint the osmotic pressure between the body cells and body fluids. Cell membranes are selectively permeable, infusing the body system with pure water will make pure water to rush into cells, dilute the contents and make the cells to swell up.

I belive that the correct answer is you will undergo a condition called metabolic acidosis.

Explanation:

The pH of blood is 7.35 and the pH of pure water ranges from 7-8.5 but it is most steady at a pH of 7. Infusing tap water would prove to be detrimental due to a combination of problems. Pure water contains minerals and ions that make the pH of the water more acidic. Adding an acidic liquid into the bloodstream directly will cause a spike of blood pH. To balance this acidic pH, the respiration of the person will increase so that breathing will be shallow to provide oxygen while removing more carbon dioxie. CO2 contributes to the pH of the body by making the blood more acidic when it forms carbonic acid. Reducing it in circulation will increase the pH of blood. Using the lungs to balance the pH is called respiratory compensation and in the instance of metabolic acidosis, the situation will be metabolic acidosis with respiratory compensation. The body will also turn to the kidney where the kidneys will stop reabsorbing more sodium ions so that when the ions are released in urine, the pH in blood will try to stabilize. This will be a problem because water will be lost as sodium ions are lost and the person involved will start to have cardiovascular conditions such as arrhythmias and muscle spasms since sodium is essential for muscles to communicate. Dehydration would range from moderate to severe and if left unattended, the person is going to have a stroke in the brain. With the brain shutting down due to the stroke, the person will not be able to breathe as ast as the body wanted to regulate the pH. So basically, the body would sabotage itself and it is a very bad idea to try to infuse pure water. Pure water is also not sterile meaning there are microorganisms that live in it and if added into the bloodstream, they can cause severe blood infections that can lead to sepsis and this will just worsen the condition of the person over time. To diagnose the acidosis, a test called Arterial Blood Gases (ABGs) is done to asses the balance of acids and bases in the blood and find out how to correct them to return homeostasis back to normal.

Which of these features is most likely to have been formed by flowing water? sand dune canyon u-shaped valley root pry

Answers

Answer: Canyon

A canyon is a deep, narrow valley that exhibits steep sides. The canyon is usually formed on the mountains or plateaus as V shaped valley, when the rocks are weathered by the water of river and erosion by high speed wind current.

Therefore, on the basis of above information Canyon is a feature which is most likely to be formed by flowing water.

canyon is the feature that is most likely to have been formed by flowing water

How many genes do people have ?

Answers

The amount of genes we have is considered an estimation. Theyused to believe it was around or above 100,000. Then when the human genome project (HGP)was completed in 2003 their estimation brought it down to 20,000 to 25,000. Youcan find their current work at “national human genome research institute” andalso a free public database.

Shortly after the viral capsid enters the cell, an enzyme called reverse transcriptase liberates the positive-sense single-stranded RNA genome from the attached viral proteins and copies it into a complementary DNA (cDNA) molecule. True or false?

Answers

Answer:

True

Explanation:

In Retrovirus such as HIV, when the virus enters the host's cell it releases enzyme reverse Transcriptase which generates a complementary DNA(cDNA) by the process called Reverse transcription.

By this process the positive single stranded RNA genome is liberated into a cDNA molecule.

Since the process of reverse transcription is prone to errors, it can cause mutation that lead to drug resistance or enable the virus evade the body's immune system.

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate of 2.5% per year and is compounded monthly, how long does it take you to earn $3,000 without depositing any additional funds? A. 10.1101 years
B. 119.954 years
C. 121.321 years
D. 134.34 years

Answers

Principal amount deposited in a savings account = $150
Final amount of money needed = $3000
Percentage of interest = 2.5%
Let us assume the time taken = t years
Then
A = P (1 + r/n) ^ nt
3000 = 150(1 +0.025/12)^t
3000 = 150 * (1 + 0.002083)^t
(1.002083)^t = 20
Taking log on both sides we get
log (1.002083)^t = log 20
t * ln(1.002083) = ln(20) 
t = ln(20)/ln(1.002083)
  = 1439.68
  = 119.973 years
From the above deduction we can easily conclude that the correct option among all the options that are given in the question is the second option or option "B".

B.) 119.954 years
