Pull Of Gravity , that is why you have weight or else without gravitational pull you only have mass hence the equation w = mg
Photosynthesis produce 02 (oxygen)
The answer is : exponentially
Descending tracts are the pathways by which motor
signals are pass through from the brain to lower motor neurones. Thus, all
the neurones within the descending motor system are classed as upper motor
neurones. The lower motor neurones then directly innervate muscles to produce
movement. Their cell bodies are found in the cerebral cortex or the brain stem,
with their axons remaining within the CNS.
True.
It has been studied in a research study that claims birds have the ability and capability to regenerate their hair cells. This regeneration happens when the hair cells die but come back to its original form despite the damage it might have faced. Further, they can also regrow their hair cells in their ears.
