Bagian yang akan berkembang menjadi saluran pencernaan ditunjukkan oleh nomor ....
Pembahasan:
Setelah zigot memasuki fase gastrula, terjadi involusi (pelekukan) bibir dorsal blastopor ke bagian dalam rongga blastocoel yang mengakibatkan terbentuknya rongga gastrocoel atau arkenteron. Rongga arkenteron akan berkembang menjadi saluran pencernaan. Sedangkan bibir dorsal tempat involusi tersebut membentuk blatoporus, yang akan berkembang menjadi anus. Involusi sel-sel bibir dorsal ini akan terus mendesak rongga blastocoel menjadi lebih sempit dan terbentuklah 3 lapisan embrional yaitu ektoderm, mesoderm, dan entoderm.
Jadi, bagian yang akan berkembang menjadi saluran pencernaan ditunjukkan oleh nomor 2 (arkenteron).

Kau
Lihat kami!
Kami mencoba kuat diatas kekurangan
Tak lelah banting tulang
Tapi kau?
Lihat dirimu!
Kau tak bersyukur dengan dirimu
Kau curi hak kami
Kau biarkan kami menderita
Tapi kau?
Seakan menari-nari diatas penderitaan kami
Lihat kami!
Apa tak kau lihat keringat kami?
Keletihan kami
Hanya demi sesuap nasi
Lihat negeri ini!
Sudah tiadakah hati?
Sudah tiadakah mata?
Hingga tak pernah kau lihat kami
Lalu, harus kemanakah kami?
Kami memang tak mampu balas dirimu
Karena Tuhan yang akan balas dirimu

This is Michelle’s living room. (1) There aren’t many furnitures in it because she likes to keep everything clean and tidy. (2) There are only a small cabinet, a big yellow couch, and a single sofa chair to sit with her family. Her cat would also rest on the couch because it is very comfortable. (3) There is no painting on the wall but Michelle prefers to add green plants to the decoration. They become new trends lately and her favorite is definitely a palm leaf. (4) There are also books on the wall. She usually reads them while enjoying a nice cup of tea in the morning.

Read the following text and answer the question.
It was Katia’s 20th birthday and she was looking forward to seeing her friends. They were meeting at Sakura Blossoms, her favorite Japanese restaurant for a special birthday dinner. Katia was excited and got the restaurant at exactly 7 o’clock, the time they had arranged to meet. She looked around for a familiar face, but no one had arrived yet. So, she decided to wait outside and stood patiently in the warm evening sunshine.
The restaurant quickly filled up with customers, but none of them were Katia’s friends. “Where are they?” she thought. At half past seven she was still waiting, so she called her best friend Isa. “Why doesn’t she answer her phone?” Katia asked herself. Then she called Jofa, Ali, and Yoko, but they didn’t answer either. “What’s going on?” she wondered.
At 8 o’clock Katia went home. Her friends had forgotten her birthday and she felt lonely and miserable. She opened the front door and walked into the dark house. The living room door was closed. “How strange,” she thought because she always left it open. Nervously, she opened the door. Suddenly, the lights went on and all her friends jumped up and shouted “Surprise!” So, they hadn’t forgotten and, in the end, it was the best birthday ever.
If you were Katia, what would you feel when you were in Sakura Blossoms restaurant at 8.00 pm?
