Can a a positive father and a o negative mother produce a a negative child?
No they can not. two positives do not make a negative
Can an O negative mother and an A positive father produce an O positive child?
Yes. The father's phenotype is AO+*; the mother's is OO--.
Can type a POSITIVE mother and o positive father have a b NEGATIVE child?
No. For two reasons: an "A" and an "O" can never produce "B," and positve blood types will never yield a negative one.
Can an O positive blood type parent produce an AB negative blood type child?
yes
What are some examples of a positive feedback loop and a negative feedback loop?
The most common by far is negative feedback, pretty much every hormone works through negative feedback. Take for example tiroxine: low levels of tiroxine induce production of TRH and TSH which in time increase production of tiroxine, and when the levels of tiroxine are high, it lowers the production of TRH and TSH, lowering production of tiroxine as well. Another example would be insulin: when blood sugar levels rise, the pancreas produces more insulin, and once it takes effect and blood sugar levels lower, the pancras stops the increased production. Positive feedback on the other hand is more rare, an example would be childbirthing, when the baby stretches the cervix, it induces production of oxytocin in the pituitary gland, which causes the contractions of the uterus, pushing the baby out and stretching the cervix even more, making the pituitary gland produce even more oxytocin
Can a negative and negative produce a 0 positive?
no
Why does a negative number times a negative number produce a positive number?
Negative times negative is always a positive.
Can an A positive father and A negative mother produce both A positive and A negative children?
Yes.
What type of feedback is most likely to produce a low self-esteem or fragile mental health?
Negative feedback.
Can an o positive and an o negative produce an o negative?
no.
How do you multiple and divide positive and negative integers?
multiplying and dividing a negative number will "flip" the sign of the other number. So multiplying two negative numbers will produce a positive number. Multiplying one positive and one negative number will produce a negative. And of course two positive numbers yield a positive.
Does flurine form a positive or negative ion?
Fluorine is negative and will produce a negative ion.
What happens during positive feedback loop?
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
Can a A positive mother an a O negative father produce a O positive child?
Yes.
Can an o positive mother and an a positive father produce an 0 negative child?
Yes
Are blood glucose levels regulated by positive feedback?
No, blood glucose concentration is regulated by negative feedback. When blood sugar levels are too high, the alpha particles in the pancreas' islets of Langerhans signal the pancreas to produce more insulin, which regulates the sugar level by stimulating the liver and other body cells to absorb more glucose at convert it into either glycogen or fat. This lowers the blood sugar concentration. If it were positive feedback, high blood sugar levels would encourage the production of more glucose to increase the blood sugar concentration.
Is negative feedback is a self-amplifying chain of events that tend to produce rapid change in the body?
No, false.
