Quiz Reproduksi Manusia Kelas 9 K13

1. Berikut organ reproduksi pada manusia yang berfungsi untuk memproduksi sperma dan hormon testosteron adalah ….

Testis

Uterus

Uretra

Skrotum

The correct answer is Testis. Testis is the male reproductive organ in humans that is responsible for producing sperm and the hormone testosterone. It is located in the scrotum and plays a crucial role in the process of reproduction. The testis consists of seminiferous tubules where sperm cells are produced through a process called spermatogenesis. Additionally, the testis is also responsible for secreting testosterone, which is essential for the development and maintenance of male reproductive tissues and secondary sexual characteristics.

2. Peristiwa berikut yang tidak termasuk pada siklus menstruasi apabila fertilisasi tidak terjadi adalah….

kehamilan

estrogen dan progesteron menurun

dinding rahim akan luruh

menstruasi

If fertilization does not occur, the body will not enter into pregnancy. Therefore, pregnancy is not a part of the menstrual cycle when fertilization does not happen. The decrease in estrogen and progesterone levels, the shedding of the uterine lining, and the occurrence of menstruation are all normal processes that happen during the menstrual cycle.

mengakses situs-situs yang menyediakan gambar atau film porno,yang secara pelan tapi pasti akan mendorong kamu dalam kehidupan seks bebas yang sangat rentan dengan penularan penyakit seksual

harus dapat menjaga pergaulan dan memilih gaya hidup yang sehat agar tidak terjebak pada seks bebas

The correct answer suggests that one of the prevention measures for HIV/AIDS is to maintain social interaction and choose a healthy lifestyle to avoid engaging in risky sexual behavior. This implies that by making conscious choices about one's social circle and lifestyle, individuals can reduce their chances of being exposed to situations that may lead to unprotected sex and potential transmission of sexually transmitted diseases like HIV/AIDS.

4. Pembelahan sel yang terjadi pada sel-sel tubuh (sel somatik) makhluk hidup yang menghasilkan sel anak yang mempunyai kromosom yang jumlahnya sama dengan kromosom sel induk disebut…..

pembelahan sel mitosis

pembelahan sel meiosis

pembelahan sel telur dan sel sperma

Pembelahan sel somatik

The correct answer is "pembelahan sel mitosis". This is because mitosis is the process of cell division in which the daughter cells produced have the same number of chromosomes as the parent cell. In this case, the question states that the cells involved are somatic cells, which are the cells of the body. Therefore, the correct answer is pembelahan sel mitosis.

5. Terdapat ciri penyakit sebagai berikut: 1. Gejala awal berupa borok pada tempat masuknya bakteri 2. Biasanya menyerang daerah sekitar kelamin 3. Disebabkan oleh Treponema pallidum Ciri-ciri penyakit di atas dimiliki oleh orang yang menderita penyakit...

sifilis

Gonorhea

Herpes Simplex Genitalis

HIV/AIDS

The correct answer is syphilis. This is because syphilis matches all the given characteristics: it starts with a sore at the site of bacterial entry, commonly affects the genital area, and is caused by the bacterium Treponema pallidum.

6. Gambar di samping menunjukkan salah satu tahap pembelahan sel secara mitosis, ciri pembelahan tersebut adalah….

Membran inti mulai rusak menjadi bagian-bagian kecil (fragmen)

Kromosom berjejer pada bidang pembelahan

Benang-benang kromatin memadat menjadi kromosom

Kromatid saudara dari setiap pasangan memisah menuju kutub yang berlawanan

The correct answer is "Kromosom berjejer pada bidang pembelahan." This is because during mitosis, the chromosomes line up at the equator of the cell, known as the metaphase plate. This alignment ensures that each daughter cell receives an equal number of chromosomes during cell division.

7. Hormon estrogen adalah memicu kembali kelenjar pituitari untuk menghasilkan hormon FSH dan LH (leuteinizing hormone). Hormon LH terus diproduksi dan meningkat secara mendadak. Peningkatan hormon LH ini akan memicu pengeluaran sel telur dari folikel yang telah matang, proses terlepasnya sel telur disebut….

menstruasi

Oogonium

Ovulasi

Oogenesis

The explanation for the correct answer, "Ovulasi," is that the hormone estrogen stimulates the pituitary gland to produce hormones FSH and LH. LH hormone is continuously produced and increases suddenly. This increase in LH hormone triggers the release of the mature egg from the follicle, which is known as ovulation.

1, 2, dan 4

1, 2, dan 3

The correct answer is 3, 4, dan 5. This is because the given characteristics of the plant Angiopermae include: the future seed is located in the future fruit (ovary), the future fruit is a swollen part of the pistil composed of fruit leaves (carpels), the future fruit will develop into a fruit and the future seed will become a seed, and the plant has a sexual reproductive organ called a strobilus or cone. Additionally, the plant's seeds are not covered by a fruit skin or are open-seeded.
