中3生物 この問題でなぜ答えが12分になるのかわからないので教えてほしいです。 (図2は二枚目に貼っておきます)

数は比例関係にあるものとする。 ･最終的に観察できた細胞は600個あり、そのうち図2の⑦のような細胞は5個だった。 タマネギの細胞分裂の周期 (分裂が開始して次の分裂が開始されるまで)を24時間と して、図2の⑦の時期の長さは何分と考えられるか。 ただし、細胞分裂の1周期の長さに 対する各分裂時期の長さの比は観察された全細胞数に対するその時期の細胞数の比に 一致するものとする。

When you start your 30 waffle shop in Japan, can I help you at the shop?" Ellen answered, "Yes. Oh, the movie will start soon. Let's go, Ayane!" "Yes, let's go," Ayane said. Ayane was happy because she understood Ellen and her country better.

1945年の4月1日に始まった沖縄戦の間アメリカ軍の島への上陸があり, 80人以上の沖縄の人々が洞窟 に避難したあとその中で自殺したと考えられています。 がこの一文の訳なのですが、believedは何に訳されているのでしょうか？？

t forced to commit suicide in the closing days of World War II, police have said. The boys, between the ages of 16 and 19, have said that they destroyed two *signboards and origami paper cranes left by visitors to the Chibichirigama cave between Sept. 5 and last Tuesday, police said Friday. 着 During the *Battle of Okinawa, which started on April 1, 1945, with the landing of the U.S. *army on the island, more than 80 Okinawa people were believed to commit suicide in the cave after taking *refuge there. Similar cases of suicide took place at other places during the battle. Family members of those people who killed themselves at the site during the war discovered the damage last Tuesday and reported it to police. Norio Yonaha, 63, who lost five members of his family in the suicide, told reporters that this was “an *insult to the people who died" there. Bottles and vases left behind by the dead people were also damaged. About 100,000 people, or almost a quarter of the local people, died in the three-month ground battle in Okinawa between the Japanese army and the U.S. army. In total, more than 200,000 (life) were lost, *including those of Americans. (2017, September 16). Japan Times Can you see “Chibichirigama” in the news report? “Gama” means “cave” in Okinawa. We can see natural gama here and there in Okinawa. Himeyurinotou is built on top of one of these gama. During World War II, gama were used as *trenches by the Japanese army and as places of refuge by Okinawa people. [ 7 ] because they had nothing to eat and no medicine for *wounds and sickness. Many were killed by the U.S. army who burned people to death. [ ] because they spoke Okinawa words. Some babies were also killed because they (cry). Many had to commit suicide because the Japanese army ordered then didn't stop to do so. [], but not always. In fact, there were lots of people who died in gama. Gama te us how terrible war is. NAZ
