2006年に冥王星が準惑星に再分類されたため、公式には8つの惑星があります。皮膚は体を完全に覆い、内部のすべてを保護し、平均的な大人では約8〜10ポンドの重さがあります。火星が地球から赤く見えるのは、その表面が酸化鉄、つまり錆と同じ化学物質で覆われているためです。平均的な安静時の心臓は1分間に約60〜100回拍動し、24時間で約10万回になります。太陽に最も近い順序は水星→金星→地球→火星で、その後巨大惑星が始まります。動脈は、心臓から血液を運ぶ丈夫で弾力性のある管です。ほとんどの動脈は明るい赤色の酸素化された血液を運びますが、肺動脈は主要な例外であり、脱酸素化された血液を肺に運びます。2025年現在、土星は145以上の確認された月を持つことでリードを奪っており、そのほとんどが氷と岩でできています。心臓には4つの部屋があります:血液を受け取る2つの上部の心房と、血液を送り出す2つの下部の心室です。白血球は、細菌、ウイルス、その他の侵入者を攻撃する免疫システムの兵士です。天王星は98度の極端な自転軸の傾きを持っており、基本的に太陽の周りを横向きに転がっています。木星は太陽系で最大の惑星です。地球の約11倍の幅があり、赤道直径は88,846マイル(約142,984キロメートル)です。心房(単数形:心房)は、静脈から入ってくる血液を心室に送る前に集めます。金星は、その厚い二酸化炭素の大気が暴走した温室のように熱を閉じ込めるため、ほぼ470℃に達します。血液は常に赤いです。酸素が豊富な場合は鮮やかな赤で、酸素が少ない場合は暗い赤になります。地球は約365.25日かかります。そのため、うるう年には1日追加されます。窒素は地球の大気の約78%を占め、酸素は約21%にすぎません。植物は葉の小さな穴から二酸化炭素を取り込み、水と組み合わせて糖と酸素を作ります。クロロフィルは植物を緑色にし、光エネルギーを化学エネルギーに変換させます。ツンドラでは、夏に解ける薄い表層を除いて、一年中地面が凍結しています。核は、細胞が必要とするすべての指示を保持するコントロールセンターのようなものです。太陽光は、光合成を通じて天気、海流、そしてほとんどすべての生命を動かします。細胞呼吸はミトコンドリアで行われ、糖と酸素をエネルギー、二酸化炭素、水に変えます。遺伝子は、体の構築と機能のための取扱説明書のように機能するDNAのセクションです。ATP(アデノシン三リン酸)は、細胞が行うほとんどすべてのことを動かす充電式バッテリーのようなものです。肝臓は胆汁を作り、脂肪の多い食べ物が届くまで胆嚢に貯蔵します。気孔は開閉して二酸化炭素を取り込み、酸素/水蒸気を放出します。炭素原子は鎖や環状に結合でき、生命に必要な複雑な分子を作ります。大赤斑は、木星の大気中にある永続的な高気圧領域であり、太陽系で最大の反サイクロン性嵐を生成します。だからパンやクラッカーを長時間噛むと、少し甘く感じ始めるのです。葉緑体は、光合成が行われる緑の工場です。生態系には、動物、植物、天気、土壌、水がすべて相互作用しています。蒸散は、ストローのように根から水と栄養素を吸い上げるのに役立ちます。血漿は、血液の黄色い液体部分で、他のすべてのものの配達トラックのように機能します。海王星は最も遠い公式の惑星なので、海王星での1年は地球の約165年に相当します。あなたの体は、これらのアミノ酸の構成要素を使って筋肉を修復し、新しい細胞を作ります。地球の表面の約71%は、海、湖、川で覆われています。Oは1文字の記号です。O₂は、私たちが呼吸する空気中で2つの酸素原子が結合していることを意味します。頭蓋骨は22個の融合した骨でできており、脳の周りに硬いヘルメットを形成しています。太陽は地球に最も近い星で、わずか約8光分離れたところにあります。植物は日光を使って自分自身の食物を生産するため、他のすべては植物に依存しています。You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40

6年生の理科で習ったことをまだ覚えていると思いますか?これは、心臓のカラフルな図を描いたり、ポスターに惑星の名前を書き込んだりした、まさにその内容です。大学レベルの物理学も、高校の化学もありません。ただ、11歳なら誰でも完璧に知っているべきことです。40問のストレートな問題です。もし2025年の6年生に負けるようなら、大人カードを返納する時です。
