Which curve shows the course of the reaction in the presence of an enzyme--the black curve or the red curve? Which line represen

I found the attached image on the internet and it really helps complete this exercise.

First question:
In the presence of an enzyme, the course of the reaction is shown by the red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.

Second question:
The activation energy is represented by line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.

Dynasties in Chinese history, or Chinese dynasties, were hereditary monarchical regimes that ruled over China during much of its history. From the inauguration of dynastic rule by Yu the Great in circa 2070 BC to the abdication of the Xuantong Emperor on 12 February 1912 in the wake of the Xinhai Revolution, China was ruled by a series of successive dynasties. Dynasties of China were not limited to those established by ethnic Han—the dominant Chinese ethnic group—and its predecessor, the Huaxia tribal confederation, but also included those founded by non-Han peoples.

Dividing Chinese history into periods ruled by dynasties is a common method of periodization utilized by scholars. Accordingly, a dynasty may be used to delimit the era during which a family reigned, as well as to describe events, trends, personalities, artistic compositions, and artifacts of that period.[8] For example, porcelain made during the Ming dynasty may be referred to as "Ming porcelain".The word "dynasty" is usually omitted when making such adjectival references.

The longest-reigning orthodox dynasty of China was the Zhou dynasty, ruling for a total length of 789 years, albeit it is divided into the Western Zhou and the Eastern Zhou in Chinese historiography, and its power was drastically reduced during the latter part of its rule.[10] The largest orthodox Chinese dynasty in terms of territorial size was either the Yuan dynasty or the Qing dynasty, depending on the historical source.[11][12][13][14][15][c]

Chinese dynasties often referred to themselves as "Tianchao" "Celestial Dynasty" or "Heavenly Dynasty"). As a form of respect and subordination, Chinese tributary states referred to Chinese dynasties as "Tiāncháo Shangguo" "Celestial Dynasty of the Lofty State") or "Tianchao Daguo" "Celestial Dynasty of the Great State")
