Nucleus, Mitochondria, and Lysosomes are found in a cell. Plastid is the odd one.
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.
A supension is formed when two or more materials are insoulable so they
rest on top of each other. For instance, sand and oil are insoulable
(unable to be mixed together) so based on density, one rises above the
other, making a suspension.

Answer:
Umm um is that a question
Answer:
a. It is a competitive inhibitor.
Explanation:
A competitive inhibitor competes with the substrate for the active site of the enzyme. Binding of the competitive inhibitor to the active site of enzyme forms enzyme-inhibitor complex and does not allow the substrate to bind to the enzyme. This inhibits the reaction. However, the competitive inhibition is overcome by increasing the concentration of substrate around the enzyme to facilitate its binding to the enzyme's active site.
According to the given information, malonic acid competes with succinate for the active site of enzyme succinate dehydrogenase and inhibits the reaction. This inhibition is overcome by increasing the succinate concentration around the enzyme. This makes malonic acid a competitive inhibitor to succinate dehydrogenase.
