Activity – 8
What does typing someone’s blood mean?
Typing someone’s blood means determining the exact type of blood a person usually has. It was make one know one’s blood – group whether ‘A’ or ‘B’ or ‘O’.
What materials are necessary to type one’s blood? Which paragraphs tell you about these materials?
Alcohol – soaked cotton balls, sterile lancet, a small test tube containing 1ml. of saline solution, anti-A anti- B and anti- Rhserum with individual eye droppers, two microscope slides, a grease pencil, a posture pipette, three applicator sticks and a warm fluorescent light or other low-heat sources are used on typing one’s blood.
What are the three stages of experimental process described in this text? Name them.
First label one slide Rh with a grease pencil and place it under the low-heat source. Divide the cool slide into two equal portions labeling one side A and B and a drop of anti- Rh to warm the Rh slide. In the second stage, use an alcohol-soaked cotton ball to swab your middle or ring finger opening the sterile lancet prick the sterile finger once. Collect several drop of blood in the tube containing saline solution. In the third stage, using the porture pipette, transfer one drop of saline solution containing blood to each of the anti- A, anti- B and anti-Rh serums using a separate applicator stick. Two or three minutes after clumping should have appeared in one or three of the areas. This clumping determines what kind of blood a person has. The stages can be named as preparatory stage, experimental stage and conclusive stage.

Like your Rh- slide experiment, you have only two tense forms of most of the English verbs, e.g. “go” and “went”. “Gone” is not a tense form. In association with the other auxiliary verbs, it gives a sense of completion of an activity“has gone”ora passive sense “is done”. Hence like Rh+ or Rh-. English verbs can be either in past tense or non-past tense.
Similarly like your blood grouping. A, B, AB or O, we can have the aspects of perfect (have + V + en), progressive (be + V + ing), perfect progressive (both combined or simple neither, perfect, nor progressive). These four aspects of either past or non-past give us the 8 types of verb groups. In addition to these two tenses and four aspects we can find do operations or model auxiliaries as elements ofa very group.
In the first sentences of the text, the verb is……used. You can see that it is be + v + en structure in simple non-past tense form. Hence, is a simple non-past passive structure.

|(ii) Non-past||(c) progressive||(ii) Passive|
|had been completed||Past||Perfective||Passive|

In order to type your own blood, you need alcohol-soaked, soaked cotton balls, a sterile lancet, a small test tube containing 1 ml. of saline solution; anti – A, anti – B and anti – Rh serums with individual eye droppers, two microscope slides; a greased pencil; a pasture pipette, three applicator sticks and a warm fluorescent light or other low heat sources. One can make a typing of one’s own blood with these terms.
- Of course, we don’t wish to learn about our blood type.

- We require two microscope slides.
- We need a grease pencil.
- We require a Pasteur pipette.
- We need three applicator sticks.
- We also require a warm fluorescent light.
- We also need other low-heat sources.
- We require label one slide Rh with grease pencil.
- We have to place this slide under the low heat source.
