Answer:
Explanation:
Bacterial count in stock- 1.85x10^6 cfu/ml
Dilution methods
Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.
Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.
Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.
Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml
So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.
If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.
Answer:
coordinates the body's functions to maintain homeostasis during rest and exercise also to initiate and control movement, and all the physiological processes movement involves!
Answer:
Exocytosis is the reverse of endocytosis. <em><u>Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules.</u></em> By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
Answer:
The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is <u>less</u>.
Explanation:
Both ATP and glucose are energy containing molecules. However, a molecule of glucose has about 90 times more energy than a molecule of ATP.
But, ATP is used by most cells as the quickest source of energy. This is because ATP can easily be broken down to generate energy and it transfers energy very effectively.
A molecule of ATP is made up of adenine and three phosphate groups. The bond between the second and third phosphate is broken down to generate energy.
The nurse should ask during the interview portion of the
developmental assessment with the parent of an infant between 10 and 12 are; First
Does your baby stand independently? Second "Is your baby able to walk with
assistance?” and "Does your baby sit from a standing position?"
