The Unopette can be used for:
A) Microcollection of blood for culture and sensitivity testing
B) Microcollection and dilution of blood samples for the WBC count
C) ABO group and type blood collection
D) Microcollection of blood for hematocrit

B) Microcollection and dilution of blood samples for the WBC count

Explanation:

The Unopette is a method that involves the microcollection and dilution of obtained blood sample for the purpose of getting a white blood cell (WBC) count. This pipetting system is accurate, convenient, easy and precise.

In the Unopette method, blood is obtained from the patient and the whole blood of the patient is then added to a diluent (3 percent acetic acid solution). When the diluent mixes with the blood, it hemolyzes or lyses the red blood cells while retaining the white blood cells or leukocyte which can be counted.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
