Ttc is a chemical indicator in a culture media used for differentiating bacteria. suppose you need to create a 500 ml solution of a 1% ttc solution (the other 99% is water). all you have to measure this volume with is a microliter pipette. how many microliters of ttc solution should you measure?

5000 microliters of TTC solution

Explanation:

It is given that  500 ml solution consists of 1% TTC

So the amount of TTC (in ml) in the solution is 1 % of 500 ml

ml

As we know

ml micro liter

So amount of TTC in micro liter present in 5 ml of TTC

micro liter

Thus there are 5000 microliters of TTC solution

im back lol i heard you where asking for me

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
