- A.
Respirasi
- B.
Bergerak
- C.
Memerlukan nutrisi
- D.
Makan dimakan
- E.

Correct Answer
C. Memerlukan nutrisiExplanation
The correct answer is "memerlukan nutrisi" because it states that the lion hunts the zebra to eat, which indicates that the lion needs to obtain nutrients from the zebra in order to survive. This aligns with the characteristic of living organisms that they require nutrition to sustain their life processes.Rate this question:

To address the concerns about global warming and its potential consequences, reducing carbon emissions (CO2) is a suitable action to take. Carbon dioxide is a greenhouse gas that contributes to the greenhouse effect, trapping heat in the atmosphere and causing the Earth's temperature to rise. By reducing carbon emissions, we can help mitigate the effects of global warming and potentially prevent natural disasters associated with it. This can be achieved through various means such as transitioning to renewable energy sources, promoting energy efficiency, and implementing sustainable transportation systems.Rate this question:

- B.

- C.
Pupil
- D.
Kornea
- E.
Aqueous humor
Correct Answer
C. PupilExplanation
The pupil is the part of the eye that regulates the amount of light entering the eye. When exposed to high-intensity light, the pupil reflexively constricts, reducing the amount of light that enters the eye. This helps to protect the sensitive structures of the eye from potential damage caused by excessive light. The iris, sclera, cornea, and aqueous humor do not play a direct role in this process.Rate this question:

Correct Answer
A. Sel limfosit B memoriExplanation
When the body is infected with the chickenpox virus and recovers, it develops immunity to the disease for a certain period of time. This immunity is caused by the formation of memory B lymphocytes. These memory B cells "remember" the specific antigens of the chickenpox virus and can quickly produce antibodies if the body is re-infected with the same virus in the future. This rapid response helps to prevent the disease from recurring or reduces its severity.Rate this question:

Sekelompok siswa membuat rancangan suatu percobaan : ditanam 5 biji kacang hijau di pot A yang ditempatkan di gelap, dan 5 biji kacang hijau di pot B yang diletakkan di tempat terbuka. Penyiraman dilakukan setiap hari dengan kuantitas yang sama untuk menjaga kelembabannya. Setelah berkecambah dan tumbuh menjadi tanaman, keadaan yang tepat untuk tanaman tersebut adalah ….

Tanaman dalam pot A berdaun hijau dan lebar
- B.
Tanaman dalam pot B berdaun tebal dan pucat

Tanaman dalam pot A berbatang tinggi kurus dan daun pucat
- D.
Tanaman dalam pot B berbatang pendek lemah dan daun kekuningan
- E.
Tanaman dalam pot A dan pot B memiliki daun hijau dan batang tinggi
Correct Answer
C. Tanaman dalam pot A berbatang tinggi kurus dan daun pucatExplanation
The explanation for the correct answer is that the plants in pot A are tall and skinny with pale leaves because they were placed in a dark environment. Lack of sunlight caused the plants to grow taller in search of light, resulting in a weak and elongated stem. The pale leaves indicate that the plants did not receive enough sunlight for photosynthesis, leading to a lack of chlorophyll and a pale appearance.Rate this question:

- E.
Sel tumbuhan direndam dalam aquades sehingga mengalami krenasi
Correct Answer
B. Darah hewan direndam dalam larutan garam 10% sehingga mengalami krenasiExplanation
The correct answer is "Darah hewan direndam dalam larutan garam 10% sehingga mengalami krenasi" because when animal blood is immersed in a 10% salt solution, it causes the cells to lose water and shrink, leading to krenation. This is because the salt solution has a higher solute concentration compared to the blood cells, resulting in water moving out of the cells through osmosis to equalize the concentration. As a result, the cells become dehydrated and shrink.Rate this question:

Correct Answer
D. 18 pasang autosom + 1 pasang kromosom seks XX/XYExplanation
The correct answer is 18 pasang autosom + 1 pasang kromosom seks XX/XY. This is because the question is asking for the karyotype of a female lion (Panthera leo) which has 38 chromosomes in each of its cells. The karyotype is a representation of the number and type of chromosomes present in an organism. In this case, the lion has 18 pairs of autosomes (non-sex chromosomes) and 1 pair of sex chromosomes, which are XX in females and XY in males.Rate this question:

Correct Answer
D. Variasi genetik dan seleksi alamExplanation
According to Darwin, the factors that play a role in the process of evolution are genetic variation and natural selection. Genetic variation refers to the differences in genes within a population, which can lead to the development of new traits over time. Natural selection is the process by which certain traits become more or less common in a population based on their fitness and ability to survive and reproduce. These two factors, genetic variation and natural selection, are essential in driving the gradual and long-term changes that occur in evolution.Rate this question:

The given information suggests that when the red-flowered plant is crossed with the white-flowered plant, all the F1 offspring have red flowers. This indicates that the red flower trait is dominant over the white flower trait. When the F1 plants are crossed with each other, 75 out of 80 offspring have red flowers and 5 have white flowers. This ratio suggests that there is a polymeric interaction between the genes, where multiple genes are involved in determining the flower color.Rate this question:

- B.
1/8
- C.
3/16
- D.
6/16
- E.
½
Correct Answer
B. 1/8Explanation
Based on the given information, Agus and Tari both have normal skin color, but their mothers are albino. This means that they both carry the albino gene, but it is not expressed in their skin color. Since Agus is butawarna (carries the gene for butawarna), there is a 50% chance that he will pass on the butawarna gene to his child. Since Tari's father is butawarna and her mother is normal, there is a 50% chance that she will pass on the albino gene to her child. Therefore, the probability of their child being both albino and butawarna is 1/2 * 1/2 = 1/4. The probability of their child being either albino or butawarna is 1/2 + 1/2 = 1/2. So, the probability of their child being albino and butawarna is 1/4 divided by 1/2, which equals 1/8.Rate this question:

The facts that support the theory of evolution according to Darwin are the presence of many different organisms (fact 2), the discovery of fossils as a record of the history of living organisms (fact 4), and the existence of variations within a species (fact 5). These facts provide evidence for the idea that species change over time and that new species can arise through the process of natural selection.Rate this question:

Pada suatu populasi manusia terdapat penderita albino 16 %, Berapa jumlah orang yang normal heterozigot jika populasi penduduk kota tersebut 50.000 orang ?
- A.

- B.
2.400 orang
- C.
3.000 orang
- D.
8.000 orang
- E.
12.000 orang
Correct Answer
E. 12.000 orangExplanation
In a population of 50,000 people, 16% are albino. This means that 84% of the population is not albino. Since the question asks for the number of people who are normal heterozygotes, we can assume that the remaining 84% of the population consists of normal individuals. To find the number of normal heterozygotes, we can calculate 84% of 50,000, which equals 42,000. Therefore, the correct answer is 12,000 people.Rate this question:
