Answer:
senses are used to messages away from the cell body of neuron
A large set of protein catalysts, called enzymes are required for both synthesis and decomposition chemical reactions
Answer:
225,563,910 m/s
Explanation:
speed of light in water = speed of light in the air/refractive index
speed of light in water = 3.00 x 10^8 m/s/1.33
speed of light in water = 225,563,910 m/s
Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, 
has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.
No, they do not. Carbon dioxide has a linear geometry because the lone pair and bond pair repulsion cancels out; however, water has a bent structure because only the oxygen atom possesses a lone pair which brings the bonding electron pairs closer.
