If atoms share two , three or more pairs of electrons..they are covalent bonds..for example, methane
if the atoms share only a lone pair of electron contributed by only one of the combining atoms but shared by both ..then it is a coordinate bond ..for example, ammonium ion
The development of vascular tissue allowed some seedless plants to C. grow taller. The vascular tissue helps transfer nutrients throughout the plant and therefore helps it grow taller.
Answer:
c. warms slowly, but holds heat longer
NPS is more harmful because difficult to regulate it
Answer:
It can be argued that the central nervous system is of equal importance to the peripheral system because the actions that signal the brain by means of nerve impulses are carried out.
That is why a central nervous system could not be executed without the innervation of the peripheral nerves to the muscles.
Explanation:
The motor cortex is part of the central nervous system and is where all kinds of signaling and many more functions are programmed. The cortex is what sends the signals to the preganglionic neurons, and this is transmitted to the postganglionic neurons where the stimulus is finally transmitted through the motor plate in the muscles.
This whole process is considered as a perfectly planned system, so it is difficult to say or decide which of the two is more important.
