Answer:
Explanation:
The total solution formed after mixing the components will be
20 μl + 20 μl + 40 μl + 120 μl = 200 μl
The smallest size tube that will hold the entire reaction is:
Firstly convert 200μl to ml
1000 μl = 1 ml
200 μl = X
X = 200 x 1/1000
X = 0.2 ml
The smallest size tube (from the options provided in the question) is 0.25 ml.
The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.
The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
Answer:
Lymphocytes
Explanation:
White blood cells ( leukocytes) is one of the formed elements of blood that provides immunity and protection against the pathogens. Different types of leukocytes are eosinophils, basophils, monocytes, lymphocytes and neutrophils.
Lymphocytes are B cells and T cells of the immune system. B cells produce antibodies against the antigen and T cells kills the harmful cells of the body. by specific cell determinants.These cells are not capable of phagocyte the pathogen.
Thus, the correct answer is option (A).
Available options are:
A. a scientific inquiry is used only by scientists.
B. scientific inquiry is a process of asking and answering questions.
C. scientific inquiry has only one correct pathway.
D. scientific inquiry often involves similar processes and practices.
E. scientific inquiry involves performing investigations and collecting data.
Answer:
B, D, E
Explanation:
Given that scientific inquiry is a term that described how people mostly scientists, observe the natural world and then come out with credible justification established on the findings that were derived.
Hence, the statements that describe scientific inquiry are:
1. B. scientific inquiry is a process of asking and answering questions. Through this, scientist want to understand the reason behind a certain phenomenon
2. D. scientific inquiry often involves similar processes and practices. To carry out scientific studies, certain steps and practices are required, regardless of the subject under study, which does not entirely change.
3. E. scientific inquiry involves performing investigations and collecting data. This is because to carry out a scientific inquiry, part of the steps and practice includes performing investigations and collecting data, regardless of the subject under study.
