Answer:
The correct answer is a. Potassium hydroxide (KOH) preparations
Explanation:
Potassium hydroxide preparation is a simple test which is carried to identify the fungal infection invaded in skin, nails, vagina, etc. KOH degrade the keratin or mucous present on sample and clears the background which makes fungal cell more visible under the microscope.
In this method sample from infected area is collected and placed in the center of the slide then a drop of KOH is added on it. After this coverslip is put on the sample and the slide is heated gently to increase the reaction rate of KOH. Then the slide containing fungus is examined under the slide. KOH test is used for both yeast and molds. So the right answer is a.
The answer to this is multicellular. Unicellular organisms' life processes all take place in the one cell which is their entire being - their entire existence - whereas multicellular organisms require specialized organs and organ systems to keep us alive.
Answer.
B. Multicellular
Answer:
53.3
Explanation:
If the objective lens is 3 times the magnification
and the magnification lens is 160X
160÷3=53.33 recurring, rounded down to be
53.3
Given parameters:
Velocity of the car = 5m/s North
Time = 9s
Unknown:
Displacement of the car = ?
Solution:
Displacement is the distance traveled in a specific direction. It is a vector quantity with magnitude and direction.
To find displacement use the expression below;
Displacement = Velocity x Time
Input the parameters and solve;
Displacement = 5 x 9 = 45m due North
The displacement of the car is 45m due North
