Gravitropism is responce to Earth's gravity. If you are talking about plants then a Positive gravitropism grows towards gravity (like roots of plant). A Negative gravitroism grows away from gravity (Like the stems of plants).
Hope this help :P

What does a positive cell voltage mean?
The reaction is spontaneous.
What do you call a plant response?
Phototropism, where the plant "turns" to arrange its leaves for better exposure to light. This process is regulated by growth regulators in the plant. Photo = light Tropism from the Greek "trope" or turning. See picture
Can o positive male and o negative female have a child?
We are looking for the possible blood types of a baby.Parental information:Mother type O pos >> is OO with Rh (++) or (+-)Father type A neg >> can be AA or AO with Rh (--)Baby recieves one gene from each parent: Baby is type AO with Rh (+-) or (--)Baby is type OO with Rh (+-) or (--)Therefore, the baby one of these blood types: Type A Rh posType A Rh negType O Rh posType O Rh negYES, an O pos mama and A neg papa can have an Rh neg child.
Where is positive feedback mechanism seen in human body?
No, positive feedback is rare, compared to negative feedback. This is because negative feedback is a self regulating cycle, so think of the regulation of heartbeats, breathing and amount of erythrocytes in the blood. The reason positive feedback doesn't occur that often is because it is not self regulating, the action of the cycle carry's on with the system. An example would be hypothermia. When your body goes below 37 degrees C, you will start to shiver to work up, if this does not work, your metabolic processes will start to slow down, you will become sleep, lethargic and lacking of energy, hence making it extremely difficult to bring heat back into the system to warm it up. Thus, the positive feedback can be a destructive mechanism. The easiest way to sum it up is that negative feedback is common as it tries to put a system back to its original equilibrium, positive feedback is rare because it is trying to make a new point for equilibrium. Hope this helps.
If the mother has type O positive blood what type of blood type does the father have to be to have a baby?
The father can have any variety of blood type. The only rare complication could occur if the father had A or B group blood, where after birth the mothers immune system attacks the babies red blood cells if it is either A or B. However, this is rare and not usually serious. You may be concerned about "Haemolytic disease of the Newborn" this mainly happens in Rheus D Negative mothers i.e. blood types A, B, AB or O negative if the baby is Rhesus D positive e.g. O positive. Plus the mother must have previously been exposed to Rhesus D positive blood e.g. previous chilbirth. But in this day and age it is very uncommon as it can be prevented both before and after birth. So you can have a baby no matter what blood type the father is.

Can a o negative blood type father have an a positive baby?
Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.

What is a false-positive?

Is punishment a reinforcer?
Punishment is not a reinforcer. there is Negative Punishment and Positive Punishment, and also Negative Reinforcement and Positive Reinforcement.*Negative Punishment is a consequence withdrawn following a response that causes a behavior to occur with less frequency.*Negative Reinforcement is a consequence withdrawn following a response that causes a behavior to occur with greater frequency.*Positive Punishment is a consequence delivered following a response that causes a behavior to occur with less frequency.*Positive Reinforcement is a consequence delivered following a response that causes a behavior to occur with greater frequency.

Is RH positive a bad blood type to have?
Being RH positive is not something you should worry about. It is neither good or bad to be RH positive. The most complications with this blood type seem to occur during pregnancy. Another slight issue which may cause concern is when a RH positive person gives or receives blood.
