- E.
Lingkungan
Correct Answer
C. Seleksi AlamExplanation
The correct answer is "Seleksi Alam" because Darwin's theory of evolution states that individuals or populations undergo changes due to environmental conditions that are less advantageous. Natural selection is the process by which individuals with traits that are better adapted to their environment are more likely to survive and reproduce, leading to the gradual change of a population over time. Therefore, natural selection is the mechanism that drives adaptation and evolution.Rate this question:

George Cuvier
Correct Answer
E. George CuvierExplanation
George Cuvier is the correct answer because he is known for his contributions to the field of paleontology and his theory of catastrophism. Cuvier believed that species became extinct due to sudden catastrophic events, and new species would then arise to fill the ecological niches left vacant by the extinct ones. This aligns with the statement in the question that living creatures appear for a moment and then disappear due to catastrophe, only to be replaced by new living creatures. Alfred R. Wallace and August Weismann are not associated with this theory.Rate this question:

Correct Answer
C. 2 dan 3Explanation
The basis of the theory of evolution is the fact that there is variation among individuals within a species (fact 2) and the presence of many homologous organs (fact 3). These two facts support the idea that species change over time through the process of natural selection, with individuals possessing favorable variations being more likely to survive and reproduce. The presence of variation and homologous organs provides evidence for common ancestry and the gradual change of species over generations.Rate this question:

Correct Answer
D. 2 dan 4Explanation
The correct answer is 2 and 4. According to Darwin's theory of evolution, giraffes with long necks evolved from giraffes with short necks (statement 1) and in the past, there were both giraffes with long necks and giraffes with short necks (statement 2). This suggests that giraffes with long necks were able to survive and reproduce, while giraffes with short necks did not survive (statement 4). Therefore, statements 2 and 4 are related to the evolution of giraffes according to Darwin's theory.Rate this question:

- D.
Evolusi terjadi secara bertahap dalam jangka waktu yang panjang
- E.
Hibridasi berbagai sifat akan menghasilkan individu baru
Correct Answer
B. Kulit organisme akan menjadi gelap akibat sinar matahariExplanation
The statement "Kulit organisme akan menjadi gelap akibat sinar matahari" does not describe a mechanism of evolution. It is more related to the adaptation of organisms to their environment, specifically the darkening of skin due to sunlight exposure. Evolution, on the other hand, refers to the process of genetic changes in populations over time, leading to the emergence of new species.Rate this question:

- B.
Adanya organisme yang punah
- C.
Adanya kecenderungan populasi bertambah banyak
- D.
Adanya perjuangan spesies untuk mempertahankan kelangsungan hidupnya
- E.
Adanya kenyataan bahwa pertumbuhan populasi tidak berjalan terus menerus
Correct Answer
D. Adanya perjuangan spesies untuk mempertahankan kelangsungan hidupnyaExplanation
Charles Darwin's theory of evolution is based on several observations, including the presence of variation within a species, the extinction of organisms, the tendency of populations to increase, and the fact that population growth does not continue indefinitely. However, the idea of "struggle for survival" is not explicitly mentioned as one of Darwin's observations. This concept, also known as natural selection, is a key component of his theory and explains how certain traits become more prevalent in a population over time.Rate this question:

Menurut teori evolusi Darwin makhluk hidup akan melakukan suatu usaha “struggle for life” yang berarti….
- A.
Untuk bereproduksi perlu adanya makanan dan ruang yang cukup
- B.
Populasi yang kuat akan terus hidup
- C.
Bertambahnya individu tidak berjalan terus-menerus
- D.
Setiap populasi cenderung bertambah banyak
- E.
Terjadinya perjuangan untuk mempertahankan hidup
Correct Answer
E. Terjadinya perjuangan untuk mempertahankan hidupExplanation
Menurut teori evolusi Darwin, makhluk hidup akan melakukan suatu usaha "struggle for life" yang berarti terjadinya perjuangan untuk mempertahankan hidup. Dalam lingkungan yang terbatas, terjadi persaingan untuk mendapatkan sumber daya seperti makanan dan ruang. Hanya individu yang paling kuat dan mampu bertahan dalam persaingan ini yang akan terus hidup dan bereproduksi, sementara individu yang lebih lemah akan mati atau tidak mampu berkembang biak. Oleh karena itu, perjuangan untuk mempertahankan hidup menjadi faktor penting dalam evolusi makhluk hidup.Rate this question:

- C.
Burung finch mengalami modifikasi
- D.
Perbedaan paruh terjadi karena seleksi alam
- E.
Burung finch mengalami evolusi melalui mutasi buatan
Correct Answer
A. Perbedaan paruh burung disesuaikan oleh mutasi alamiExplanation
The correct answer is "perbedaan paruh burung disesuaikan oleh mutasi alami." This is because Darwin observed the diversity in beak shapes and sizes among the finches in the Galapagos Islands compared to those in America. This observation supports the idea that natural selection acts on variations in traits, such as beak shape, that are produced through natural mutations.Rate this question:

- C.
Zygot sampai gastrula
- D.
Morula sampai gastrula
- E.
Zygot sampai blastula
Correct Answer
B. Zygot sampai morulaExplanation
The correct answer is "Zygot sampai morula." This is because the question is asking about the developmental stages of a zygote in various classes of vertebrate animals. The zygote is the fertilized egg, and it undergoes several stages of development before becoming an adult. The morula stage occurs after the zygote undergoes several rounds of cell division, resulting in a solid ball of cells. Therefore, the correct answer is the stage from zygote to morula.Rate this question:

Correct Answer
B. 6400 dan3200Explanation
In a population of 10,000, 4% of the people are albino. This means that there are 400 albino individuals. The question asks for the ratio of the number of individuals with normal homozygous skin color to the number of individuals with heterozygous skin color. Since homozygous individuals have two copies of the normal allele, there would be 6400 individuals with normal homozygous skin color. Heterozygous individuals have one normal allele and one albino allele, so there would be 3200 individuals with heterozygous skin color. Therefore, the correct answer is 6400 and 3200.Rate this question:
