Answer:
The compound boron trifluoride, BF3, does not have non-bonding valence electrons and The following diagram shows four possible orientations of the O-H bonds. but the other configurations would give two different CH2Cl2 compounds. structure consisting of a simple chain of four carbon atoms, CH3CH2CH2CH3.
Explanation:
take notes
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. Draw and label the structure of a typical nerve cell.
This type of transport is an example of secondary active transport
Secondary active transport is a form of active transport in
which there is movement of an ion with another molecule across a
transport membrane. This form of transport use the energy stored in the electrochemical
gradient of an ion to drive the movement of another solute such as sucrose
against a concentration.
