Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...
a.No, both bonds are highly polar.
b.Yes. O attracts electrons more strongly than C.
c.Right! O is electronegative, so O2 is polar.
d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
e.No way. C is more electronegative than O.
Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
Explanation:
Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.
Answer:
D
Explanation:
I believe the answer would be aquaporins
These cells are likely to use large amounts of ATP.
Answer:
circulatory system
Explanation:
carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses.
Answer:
<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.
<u>Sensory neurons </u>move information towards the central nervous system for processing.
<u>Interneurons </u>carry information from one type of neuron to another.
Explanation:
- Neurons are basic structural and functional units of Nervous system.
- Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
- Neurons can be classified on the basis of their structure and function.
- On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
- On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
