Hi! Guess what! I started going to the public library in my city. I sometimes have to get some information for my homework. My father suggested studying at the public library. I'm a member of the library, so I can use it for free. I like studying at the library, but it's far from my home. It takes 20 minutes to cycle there. Do you think that more people will use public libraries in the future? Your friend, Isabella Hi, Isabella! Thank you for your e-mail. 解答欄に記入しなさい。 Best wishes,

You are preparing a presentation for the school science club, using this article from a scientific website. Reaching a Tipping Point: What to Do About the Problem of Space Junk? For over fifty years, slowly at first, but with increasing intensity, we've been sending objects up into orbit. Most of these items begin life as useful 使節を開始する有用な devices, such as the thousands of satellites that bring us information and give 装置として us our 21st century communication, but even these eventually fall out of use 結仕 使われなくなる or break. These satellites, living or dead, share an increasingly crowded layer, 混雑した層 known as near-earth orbit, with rocket parts, tools, and pieces of metal from objects that have already crashed together and broken into pieces. 粉々になる ?? This garbage poses a threat both (to working" satellites of which there are thousands), and (to the earth itself.) For example, in 2009 a disused Russian 使われなくなった module crashed into an active US satellite) destroying both and forcing the International Space Station to change course to avoid the thousands of broken ためらう pieces. While most junk that falls back to earth burns up in the atmosphere. 大気圏上空で larger chunks can occasionally hit the ground, posing a threat to people and Pieces that do burn up] leave pollutants in the atmosphere, such as Property aluminum particles, which can destroy the ozone layer アルミニウム 粒子 It's clear that removing space junk is vital if we are to maintain and build upon our current satellite network. The problem has been discussed continuously since the 1970s, when Donald Kessler, a senior scientist at NASA 継続的に described a scenario (later known as Kessler syndrome) (where a runaway 制御不能の others more and more likely. While the 2009 incident may be the first large cycle of collisions begins, with each collision creating more debris, making 衝突のサイクル near-earth collision, it is thought that Kessler syndrome has already begun with smaller objects. Since Kessler syndrome was first described, many solutions have been proposed, from using lasers to robotic garbage collectors, but cost has been an obstacle to most. In 2021, a Japan-based company named Astroscale launched ELSA-d (short for "End-of-Life Services by Astroscale Demonstration") to show

It has also been doing incredible work for the environment. In 2018, the center started a project to collect used plastic bottles and 2 them into owl houses. Plastic bottles are an increasingly sight in our rivers and oceans. By reusing these plastic bottles, the center can build more nesting. boxes for owls and also ensure that less plastic ends up in the ocean. The project has been a 4 success, and the center is now raising money to buy a ship that will collect plastic directly from the ocean.

赤線部について質問です。 リン酸化はATPによってされるものなのですか？🙇🏻‍♀️

C ストロマで起こる反応 (NADPH, ATPの利用) ストロマでは、チラコイドの反応で合成され たNADPH と ATPを用いて, 二酸化炭素が固 定され, 有機物が合成される。 この反応経路は, 多くの酵素が関与する化学反応からなり, カ かいろ Calvin cycle Guide ガイド NADPH 光チラコイドで 起こる反応 ストロマで 起こる反応 ATP 葉緑体 177 有機物 ルビン回路と呼ばれる。カルビン回路の反応過程は,二酸化炭素の有機物への固定。 PGAの還元 RuBPの再生の3つの段階に分けることができる。 ●二酸化炭素の固定 カルビン回路では,細胞内に取り込まれた二酸化炭素は,まず Cs化合物であるリブロースビスリン酸 (RuBP) と反応し, C3 化合物であるホスホグ bulose 1,5-bisphosphate- phosphoglycerate リセリン酸 (PGA) 2分子となる。 この反応は, RuBPカルボキシラーゼ/オキシゲナー ribulose 1,5-bisphosphate carboxylase/oxygenase ゼ (RubisCO, ルビスコ) と呼ばれる酵素によって促進される (図1)。 ●PGAの還元 PGA は, ATP によってリン酸化されたのち, NADPHによって還 元され, C3化合物であるグリセルアルデヒドリン酸 (GAP) となる (図9-②)。 glyceraldehyde phosphate RuBP の再生 GAPの多くは、いくつかの反応を経たのち, RuBPに戻る(図3)。 カルビン回路では, 6分子の二酸化炭素につき, 18分子のATPと12分子のNADPH が消費されて2分子のGAPが同化産物として得られ, 光に由来するエネルギーがこれ に貯えられる。このGAPが糖などの有機物に変えられ, 生命活動に利用される。
