maaf mau nanya:

 mengapa struktur tulang berbeda antara sebelum direndam HCL dan setelah direndam HCL?

makasih mbak dan mas.. 

 

Tulang yang direndam dalam larutan HCL akan berubah strukturnya karena kalsium dalam tulang bereaksi dengan HCL. Reaksi itu adalah sebagai berikut:

CaCO₃ + 2 HCL --> CaCL₂ + H2CO3(langsung bereaksi)

                             endapan

H₂CO₃ --> H₂O + CO₂

Setelah terjadi reaksi tersebut tulang menjadi lentur

Saya kesulitan menemukan teks bacaan yang sebagian besar memuat tentang ADJECTIVE CLAUSE (jarang sekali teks bacaan yang menggunakan kata2 seperti WHO, WHOM, WHOSE, WHICH, WHERE, WHEN di dalamnya). Kalau pun ada, hanya ada 1 atau 2 kata yang masih berkaitan dengan ADJECTIVE CLAUSE. Bolehkah saya meminta contoh2 teks bacaan yang banyak memuat kata2 yang berhubungan dengan ADJECTIVE CLAUSE TERSEBUT?

Sebelum & sesudahnya, saya ucapkan terima kasih.

ini saya ada contoh text nya:

Some times ago in a meeting with the OPEC members, the president felt very
embarrassed because Indonesia, our beloved country, is the third most corrupt country in the orld. The fact has made the president decide that wiping out corruption must be the first riority I his program. The president himself leads the movement. He instructed his staffs to truggle hard against corruption
People believe that there are effort is successful. This is because many members of
the House of Representative in the district level were arrested. Many6 bank directors were in ail. Some government staffs were also arrested. They were proved to corrupt money in their nstitutions.
However, I believe that there are many other people who have corrupted money, but
they haven’t been arrested and processed. This was because they were so ‘clever’ in hiding he evidence of their corruption that the law in our country cannot put them in jail. In this ase, there must be some kinds of mechanism to uncover the corruption cases.
I also believe that there are still some kinds of “protection” to certain people, so that
they seemed like the ‘untouchable man’. Besides that, the existence of many ‘old men’ in very institution made the struggle against corruption felt harder. The ‘old men’ have been  ccustomed to corruption actions. It is also possible that some of them have also corrupted in he past time, so when they are urged to fight against corruption, they feel it hard, and of ourse, uncomfortable.
If these kinds of people are still found in every part of the country’s life, how can we
fight against corruption effectively? However, we must not underestimate what the
government has done to fight against corruption. The effort has been much better and harder han that of the previous time.

bu/pak saya ingin tau tentang adverb. minta tolong beri contoh saya 5 soal erorr recognition tentang adverb beserta jawabannya.. trimakasih

SEBELUMNYA SILAKAN DIPELAJARI DULU INI:

Adverbs

An adverb is a word that tells us more about a verb. An adverb "qualifies" or "modifies" a verb (The man ran quickly). But adverbs can also modify adjectives (Tara is really beautiful), or even other adverbs (It works very well).

Many different kinds of word are called adverbs. We can usually recognise an adverb by its:

1. Function (Job)
2. Form
3. Position

1. Function

The principal job of an adverb is to modify (give more information about) verbs, adjectives and other adverbs. In the following examples, the adverb is in bold and the word that it modifies is in italics.

• Modify a verb:
  - John speaks loudly. (How does John speak?)
  - Mary lives locally. (Where does Mary live?)
  - She never smokes. (When does she smoke?)
  
• Modify an adjective:
  - He is really handsome.
  
• Modify another adverb:
  - She drives incredibly slowly.

But adverbs have other functions, too. They can:

• Modify a whole sentence:
  - Obviously, I can't know everything.
  
• Modify a prepositional phrase:
  - It's immediately inside the door.

2. Form

Many adverbs end in -ly. We form such adverbs by adding -ly to the adjective. Here are some examples:

• quickly, softly, strongly, honestly, interestingly

But not all words that end in -ly are adverbs. "Friendly", for example, is an adjective.

Some adverbs have no particular form, for example:

• well, fast, very, never, always, often, still

3. Position

Adverbs have three main positions in the sentence:

• Front (before the subject):
  - Now we will study adverbs.
  
• Middle (between the subject and the main verb):
  - We often study adverbs.
  
• End (after the verb or object):
  - We study adverbs carefully

sayaingin bertanya...

ada soal begini: pak budi mempunyai empat buku yang berbeda dan seriap buku punya 3 salinan. tentukan banyak cara yang berbeda untuk menyusun buku tersebut dalam rak buku!

sesuai dengan permutasi dari objek jika berapa elamen sama saya menjawab:

(4x3)!/3!3!3!3! jadi 12!/3!3!3!3!. tapi guru sy menjawab dengan 12! itu diganti dengan 16! karena jumluh buku beserta 3 slinan ada 4x4=16.lalu bagaiamana yang benar apa cara saya atau cara guru sy. tolong jelaskan alasannya!

Leesa, sudah lama tidak mengirim pertanyaan ya ...menurut kami kata setiap buku punya 3 salinan berarti setiap buku beserta salinannya menjadi 4 buku sehingga jumlah buku beserta 3 salinan ada 4x4=16 karena itu banyak cara menyusun semua buku yang ada adalah 16!/4!4!4!4!

 Kikieo, saya beri contoh percakapan dengan ungkapan curiousity. Tetapi Kikieo lengkapi dulu ya...

Complete the dialogue with the expressions in below.

Is snoring harmful Mrs. Dian?
What do you mean by a deviated septum?
Mrs. Dian, may I ask you some questions?
Do you know what causes people to snore?

Rina: …..(1)
Mrs. Dian: What is it, dear?
Rina: It’s about my dad. Lately he has been snoring in his sleep. I can hear his snoring from my room. It is pretty loud. …..(2).
Mrs. Dian: Many things, Rina. People snore because they have allergies, catch a cold, or probably have a sinus infection. Also, if a person is overweight or drinks alcohol, they are most likely to snore in their sleep.
Rina: Well, my dad is not overweight and he doesn’t drink.
Mrs. Dian: Ha..ha..ha.. I do not say he drinks or being overweight. I was just telling you some of the reasons why people snore, Rina.
Rina: ….. (3)
Mrs. Dian: No, but only if the reasons are what I have mentioned before. It can be easily cured. But, I know there are people who have surgeries since they have a very deviated septum. It is not only to make them stop snoring but also to help them to breathe better.
Rina: ….. (4).
Mrs. Dian: It is a condition where the tissue and cartilage that separates the two nostrils in a person’s nose is crooked.
Rina: Oh, well. I should tell my dad to visit his doctor.
Mrs. Dian: You definitely should. Snoring is more a symptom than the actual diseases. Give my regards to your father, Rina. I hope he will feel better, soon.
Rina: Thank you, Mrs. Dian. Have a good day!
