1. Jika ada tumbuhan yang  tumbuh ke arah matahari, berarti tumbuhan itu bereaksi terhadap rangsangan yang berupa 

Explanation

Tumbuhan yang tumbuh ke arah matahari bereaksi terhadap rangsangan berupa cahaya. Cahaya matahari merupakan sumber energi penting bagi tumbuhan untuk melakukan proses fotosintesis. Tumbuhan memiliki kemampuan untuk merespons cahaya dan mengarahkan pertumbuhannya menuju sumber cahaya yang optimal. Ini disebut fototropisme positif, di mana tumbuhan tumbuh ke arah cahaya untuk mendapatkan energi yang dibutuhkan untuk pertumbuhan dan perkembangannya.

2. Proses pernapasan sebenarnya adalah proses 

Explanation

The correct answer is "Menghirup oksigen dan melepaskan karbon dioksida." This is because the process of respiration involves inhaling oxygen and exhaling carbon dioxide. Oxygen is taken in by the body and transported to the cells, where it is used in cellular respiration to produce energy. Carbon dioxide, a waste product of cellular respiration, is then released from the cells and exhaled out of the body.

Submit
3. Alat indra yang berfungsi sebagai alat peraba adalah 

Explanation

Kulit berfungsi sebagai alat peraba karena kulit memiliki banyak reseptor sensorik yang peka terhadap sentuhan dan tekanan. Receptor-receptor ini mengirimkan sinyal ke otak saat kulit kita bersentuhan dengan benda atau permukaan lainnya. Dengan demikian, kulit memungkinkan kita untuk merasakan tekstur, suhu, dan tekanan dari lingkungan sekitar kita.

Submit
4. Cara berkembang biak pada  makhluk  hidup ada yang secara kawin dan tak kawin. Secara tak kawin dapat dilakukan dengan cara 

Explanation

Some organisms reproduce asexually by forming spores and dividing themselves. This process does not involve mating or laying eggs. Instead, the organism creates spores, which are small reproductive cells, and then divides itself into two or more separate organisms. This allows the organism to reproduce without the need for a mate or the production of eggs.

Submit
5. Proses perubahan ukuran tubuh pada makhluk hidup sehingga bertambah besar disebut 

Explanation

Pertumbuhan dan perkembangan adalah proses perubahan ukuran tubuh pada makhluk hidup sehingga bertambah besar. Pertumbuhan mengacu pada peningkatan ukuran fisik, seperti tinggi atau berat badan, sedangkan perkembangan melibatkan perubahan dalam struktur, fungsi, dan kemampuan organisme. Keduanya saling terkait dan penting dalam siklus kehidupan makhluk hidup.

Submit
6. Makanan harus dicerna agar sari-sarinya bisa diserap oleh organ tubuh kita. Pencernaan makanan berlangsung di 

Explanation

The correct answer is "Mulut, lambung, dan usus". This is because the process of food digestion starts in the mouth where it is broken down into smaller pieces by chewing and mixed with saliva. The partially digested food then travels to the stomach where it is further broken down by stomach acids and enzymes. Finally, the nutrients from the food are absorbed in the small intestine, which is a part of the digestive system. The kidneys and esophagus mentioned in the other options are not directly involved in the digestion process.

Submit
7. Agar bisa membuat makanan sendiri, tumbuhan hijau memerlukan 

Explanation

Plants require oxygen and water in order to make their own food through the process of photosynthesis. Oxygen is needed for respiration, which releases energy for the plant to use in various cellular processes. Water is necessary for the transport of nutrients and minerals from the roots to the rest of the plant. Additionally, water is a key component in photosynthesis, as it provides the hydrogen atoms needed for the synthesis of glucose. Therefore, the correct answer is oxygen and water.

Submit
8. Pada proses fotosintesis menghasilkan 

Explanation

During the process of photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose (a type of carbohydrate) and oxygen. However, they do not directly produce proteins, fats, or vitamins through photosynthesis. These other nutrients are synthesized through various metabolic processes in plants or obtained from the soil. Therefore, the correct answer is protein, as it is not directly produced during photosynthesis.

Submit
9. Berikut ini yang bukan termasuk ciri makhluk hidup  adalah 

Explanation

Berkembang biak adalah salah satu ciri khas makhluk hidup. Makhluk hidup memiliki kemampuan untuk mereproduksi diri mereka sendiri, baik secara seksual maupun aseksual, untuk mempertahankan kelangsungan hidup spesies mereka. Peka terhadap rangsangan, mengeluarkan gas, dan bergerak juga merupakan ciri-ciri makhluk hidup.

Submit
10. Saat  bernapas, terjadi pertukaran gas dalam tubuh kita. Pertukaran gas tersebut terjadi pada organ 

Explanation

The correct answer is "Jantung" because the question is asking about the organ where gas exchange occurs during breathing. The heart is not involved in gas exchange, while the liver and kidneys have other functions unrelated to gas exchange. The lungs, on the other hand, are responsible for the exchange of gases, specifically oxygen and carbon dioxide, during the process of breathing.
