15. Tolong sekali ada tugas kimia disuruh translate artikel kimia dari inggris ke indonesia.tolong di bantu yang pandai bahasa inggris Oxidizing Agent in The Body Oxidation-reductions are used all the time. Burning, bleaching, batteries, metallurgy, and photography all rely on oxidation-reduction reactions. An important application of oxidation-reduction reactions is in electrochemical cells. (These types of cells should not be confused with biological cells. The word cell comes from cella, Latin for chamber or small room.) In an electrochemical cell, the oxidation reaction is physically separated from the reduction reaction, and the electrons pass between the two reactions through a conductor. Oxidation occurs at the anode and reduction occurs at the cathode. Oxidation-reduction reactions are responsible for food spoilage. The main source of oxidation is oxygen from the air. Preservatives that are added to foods are often reducing agents. Oxidation reactions are important in many reactions that keep our bodies going. But oxidation has also been blamed for aging, cancer, hardening of the arteries, and rheumatoid arthritis. Research is being done to evaluate the benefits of antioxidants in foods and dietary supplements. Antioxidants are natural reducing agents, such as fat soluble vitamin E and vitamin C (ascorbic acid). These substances might inhibit damaging byproducts of oxidation reactions that can occur in the human body after exposure to some toxic chemicals. One concern that scientists studying antioxidants have is that substances do not always act the same way in the human body that they do outside of it. For example, vitamin C is a reducing agent. If lemon juice is squirted on a cut apple, the vitamin C in the juice will prevent the browning of the apple that is caused by oxidation of the apple by the air. However, vitamin C might act as an oxidizing agent in the body.
Pengoksidasi agen di tubuhOksidasi-reduksi digunakan sepanjang waktu. Terbakar, pemutihan, baterai, metalurgi, dan fotografi semua bergantung pada reaksi oksidasi-reduksi. Sebuah aplikasi penting dari reaksi oksidasi-reduksi dalam sel elektrokimia. (Ini jenis sel tidak harus bingung dengan sel biologis. Sel berasal dari kata cella, bahasa Latin untuk ruang atau kamar kecil.) Dalam sel elektrokimia, reaksi oksidasi secara fisik terpisah dari reaksi reduksi, dan elektron melewati antara dua reaksi melalui konduktor. Oksidasi terjadi pada anoda dan reduksi terjadi di katoda.
Reaksi oksidasi-reduksi bertanggung jawab untuk pembusukan makanan. Sumber utama oksidasi oksigen dari udara. Pengawet yang ditambahkan ke makanan sering pereduksi.
Reaksi oksidasi yang penting dalam banyak reaksi yang menjaga tubuh kita akan. Tapi oksidasi juga telah disalahkan untuk penuaan, kanker, pengerasan arteri, dan rheumatoid arthritis. Penelitian yang dilakukan untuk mengevaluasi manfaat antioksidan dalam makanan dan suplemen makanan. Antioksidan adalah zat pereduksi alami, seperti larut dalam lemak vitamin E dan vitamin C (asam askorbat). Zat-zat ini mungkin menghambat produk sampingan yang merusak reaksi oksidasi yang dapat terjadi dalam tubuh manusia setelah terpapar beberapa bahan kimia beracun. Salah satu kekhawatiran bahwa para ilmuwan mempelajari antioksidan adalah bahwa zat tidak selalu bertindak dengan cara yang sama dalam tubuh manusia yang mereka lakukan di luar itu. Misalnya, vitamin C adalah agen mengurangi. Jika jus lemon yang disemprotkan pada luka apel, vitamin C dalam jus akan mencegah browning apel yang disebabkan oleh oksidasi apel oleh udara. Namun, vitamin C mungkin bertindak sebagai agen pengoksidasi dalam tubuh.

17. identify whether the sentences use parallelism or not/corrcet them if they are not parallel
Jawaban:
1, The sentence uses Paralellism (correct)
2. The correct sentence should be:
Either the blue shirt or the white shirt will look good with your jeans.
3. The sentence uses Paralellism (correct)
4. The correct sentence should be:
Farah and I will both watch movie and have lunch tomorrow.
5. The correct sentence should be:
When his wife is not at home, Mr. Jack not only cooks for his son but also cleans the ....... (kepotong gambarnya)
Penjelasan:
Parallellism adalah kesejajaran dalam penggunaan bagian kalimat dalam kalimat majemuk,, baik kesejajaran struktur maupun tense nya.
Kalimat majemuk adalah kalimat yang mempunyai entah dua subjek kalimat, dua verbm dua objek dst.
Jika kalimat memiliki dua subjek atau dua objek, atau dua verb maka pemakaian dalam kalimat harus paralel (sama struktur dan tense nya).
Contoh kalimat 2:
Either the blue shirt or wearing the white shirt will look good with your jeans.
Di sini ada dua subjek kalimat:
1) blue shirt
2) wearing the white shirt
Kalau diperhatikan, keduanya tidak paralel. Maka bagian nomor 2) kita perbaiki menjadi 2)the white shirt (tanpa wearing) . Barulah keduanya paralel.
Contoh lain, kalimat4:
Farah and I will both watching movie and have lunch tomorrow.
Di sin iada 2 vern:
1) watching
2) have lunch
Kita perhatikan, keduanya tidak paralel, karena ada dalam bentuk verb1, ada dalam bentung verb-ing.
KIta perbaiki dengan melihat kalimatnya secara keseluruhan, maka kita ganti watching jadi watch.
