The newly elected government, however, was supportive of the arts. It introduced a landmark policy to provide financial aid to museums so that they would drop their entrance fees. As a result, entrance to many national museums, including the Natural History Museum, became free of charge. Supporters of the policy said that as it would widen access to national museums, it would have significant benefits. People, regardless of their education or income, would have the opportunity to experience the large collections of artworks in museums and learn about the country's cultural history. Although surveys indicated that visitors to national museums that became free increased by an average of 70 percent after the policy's introduction, critics claimed the policy was not completely successful. This increase, they say, mostly consisted of the same people visiting museums many times. Additionally, some independent museums with entrance fees said the policy negatively affected them. Their visitor numbers decreased because people were visiting national museums to avoid paying fees, causing the independent museums to struggle financially.

どうして①〜⑥は交点の部分を考えているのですか??

化学 3 タンパク質を酵素で加水分解すると,種々のアミノ酸の混合物が得られる。こ れらのアミノ酸の分子は,同一の炭素原子にカルボキシ基とアミノ基が結合して HOOD = いる。これらは,タンパク質の構成成分であり,R-CH(NH2 ) COOHで表され, α-アミノ酸とよばれる。 タンパク質は α-アミノ酸がペプチド結合で多数連なっ HOOD たポリペプチドである。ペプチドのアミノ基が残った末端をN末端,カルボキ HOOD HO シ基が残った末端をC末端という。 HOOD-HO いま,アミノ酸7個からなる直鎖のヘプタペプチド X について,以下の実験 (ab) を行った。なお, ヘプタペプチド X を構成するアミノ酸はグリシン、ア ラニン、アスパラギン酸, リシンの4種類であることがわかっている。これらを 仮にA~Dとする。 実験a ペプチドのC末端側からアミノ酸を順次切り離していく酵素であるカ ルボキシペプチダーゼを使って, ヘプタペプチド Xのアミノ酸の配列順序 を決定する実験を行った。 1molのヘプタペプチドXをこの酵素で加水分 解し,切り離されたアミノ酸 A,B,C,D の物質量を反応時間ごとに追っ て測定すると,次のグラフに示す結果が得られた。 71 A:2mo/ B3nol C:lol Pilmal アミノ酸の物質量 2 アミノ酸C アミノ酸B アミノ酸A [mol] アミノ酸 D 0 反応時間 (VI) 実験 b得られたアミノ酸A~DをPHがおよそ6の緩衝液に入れ電気泳動を 行った。 ②
