Can a o- mother and a o positive father have an AB baby?
blood type is a common inheritance feature so its likely that the child will have the same blood type as the mother or father however it is possible for the baby to have a completely different blood type
What is the difference between CK isoforms and isoenzymes?
isoform and isoenzymes are two different words for the same thing.
Creatine kinase is an enzyme found in muscle and brain tissues. The different isoenzymes include MM, MB, and BB. The MM isoform is found primarily in skeletal muscle, the BB isoform is found primarily in brain tissue, and the MB isoform is found primarily in cardiac muscle.

A biosensor is an analytical device which converts a biological response into an electrical signal. The term 'biosensor' is often used to cover sensor devices used in order to determine the concentration of substances or other parameters of biological interest even where they do not utilise a biological system directly for example blood oxygen sats measurments taken by light absorbance measuments.
Answer
A biosensor is an analytical device which consists of 1) biologically sensitive element (frequently and enzyme or antibody). 2)a transducer to transform the signal into another form (eg colour change resulting from an enzyme reaction becomes an electrical signal) 3)An output device e.g. screen/printer.
Almost every dipstick test used by doctors and avalible at your chemist's can be considered a simple form of biosensor. Biosensors relying on colour changes are commonly avalible in the UK over the counter as pregnancy tests and cholesterol test strips the analytes being HCG and Total and/or HLD cholesterol depending on manufacturer.
Biosensors offer the potential for point of care testing as they can be portable and easy to use. The most sucessful biosensor to date is the glucose biosensor used be many diabetics to monitor blood glucose levels. The glucose biosensor is an amperometric device relying on the current generated when glucose oxidase reduces FAD to FADH2 and the resulting FADH2 is then oxidised by an electrode held at constant +ve voltage.
The glucose sensor is sucessful as there is a relativly large concentration of glucose in blood plasma, other biologically relevant analytes are not so abundant and amplification of the signal must be achieved. Amplification by carrier systems for electons and membrane bound electron transfer pathways are common research themes.
On a drug screen when soma test positive what class does it come under?
It shows a false positive as Benzodiazepines!!
Can a O positive and B negative produce baby A negative?
Yes. The long answer is to distinguish phenotype (the blood type A, B, AB, O) from genotype (what pair of alleles compose your genes (AA, AO, BB, BO, AB, OO).
The same goes for Rh factor (positive or negative), although the theory is more complex. The Rh + is usually taken to mean positive for the D antigen.
So parents having O (must be OA genotype) and B (must be BO genotype) blood can have a child with A ( will be AO genotype).
Can you pass an etg after 43hrs?
It depends on wath type of drugs you use. if u use weed. drink as many milk and water as you can. if u use speed. throw up once.
How long would it take 2 drinks to leave the bloodstream?
Less then two hours as soon as you drink it. It begins a process of going into the stomach and being absorbed into the bloodstream going through the brain and processed through and out the body. They say an average is one beer is one hour. So the best answer is less then two hours but more then one. Your metabolism determines how fast it goes through the body and processes the gogo juice.
You have 25 to 35 puss cell in your urine sample What does it mean?
it means that u have urinary tract infection.... contact ur doctor to get appropriate treatment
