Answer:
See figure 1
Explanation:
For this question, we have to remember that definition of an <u>"isomer"</u> in an isomer we have the<u> same condensed formula</u> (in this case ) and <u>different structures</u>. The first structure is a linear structure of 6 carbons (<u>hexane</u>). Then we can have a 5 carbon linear structure in which we have to add a methyl group. This methyl group can be attached to carbon 2 or carbon 3 (<u>2-methylpentane and 3-methylpentane</u>). Finally, we can have a 4 carbon linear structure in which we have to add 2 methyl groups. We can do this addition in carbon 2 (<u>2,2-dimethylbutane</u>) or we can do this addition in carbon 2 and carbon 3 (<u>2,3-dimethylbutane</u>).

Electron transfers between energy levels.
<h3>Explanation</h3>
An atom contains an infinite number of energy levels. An electron can exist within any one of them, but not in between. Electron can move from one level to another. However, those levels differ in energy. Energy has to conserve.
- An electron loses energy when it moves to a level of lower energy. The energy is released as radiation. The frequency of the radiation depends on the energy difference. Those radiations combine to produce an emission spectrum.
- An electron gains energy when it moves to a level of higher energy. This transfer happens only if there's an external source of energy. For example, directing a beam of white light on the atom. The beam of light would excite the electron. Again, the frequency of the radiation depends on the energy difference. Only frequencies that corresponds to transfer will be absorbed. Those radiation will eventually be released in all directions. As a result, strength of some of the radiations will be weakened. A continuous spectrum with those frequencies weakened is an absorption spectrum.
Answer:
Climatic condition in coastal regions is milder than the climatic conditions in the continental regions.
Explanation:
Climate in coastal regions is mild. It has both hot summers and winters accompanied by sea breezes. Precipitation and humidity is high in coastal areas. Both the summers and winters have a mild temperature range.
While in continental regions both summer and winters undergo extreme conditions. Summers are extremely hot and winters are extremely cold. They have wide range of climatic exposures such as rainy season, autumn season and spring season in between summer and winter season.
The function of Y would be to keep oxygen-rich blood and oxygen-poor blood separate. The last option is the correct one.
<h3>Function of the Septum</h3>
Y is the septum
The septum is a structure of the heart that separates the left atrium from the right atrium as well as the two ventricles.
Thus, the structure prevents oxygenated blood from mixing with deoxygenated blood.
