Pembahasan Soal KSM BIOLOGI MA TAHUN 2024 Tingkat Kabupaten Kota (Bagian 3)

Summary

In this video, the host discusses KSM (Kompetisi Sains Madrasah) biology questions from the 2023 exam. Topics covered include the digestion of wood by termites, population dynamics of protozoa species, and the physiological effects of listening to the Qur'an, which promotes calm and reduces stress hormones. The video also explains how bees produce honey and discusses the aging process and its analogy to Alzheimer’s disease. Each question is analyzed in-depth, providing insightful explanations of biological concepts and their real-world applications.

Takeaways

• 😀 The video focuses on discussing KSM (Kuis Sains Madrasah) biology questions at the MA/SMA level from the 2023 district and city exams.
• 😀 The first question addresses the story of Prophet Solomon's death and how termites, with the help of microorganisms in their digestive tract, break down hard wood.
• 😀 Termites digest wood through enzymes like cellulase produced by bacteria and protists in their intestines, allowing them to obtain energy from cellulose.
• 😀 The correct answer to the first question is that termites are symbiotic with protozoa and bacteria that aid in digesting wood, as indicated in the digestive system.
• 😀 The second question discusses the dynamics of interspecific competition between protozoa A and C, where Protozoa A, with faster reproduction, outcompetes Protozoa C for algae.
• 😀 Protozoa A’s larger population will consume more algae, leading to resource competition that may result in Protozoa C’s extinction in the culture.
• 😀 The correct answer to the second question is that both protozoa populations will initially increase, but Protozoa C will eventually be eliminated due to competition with Protozoa A.
• 😀 Question 14 explores the calming effects of listening to the Qur'an, which increases alpha waves in the brain and can reduce the release of stress hormones.
• 😀 The correct answer to Question 14 indicates that the adrenal gland is responsible for producing stress hormones like cortisol, which decreases with a calm heart from listening to the Qur'an.
• 😀 Question 15 explains that honey, produced by bees, is made from nectar transformed in the digestive tract of bees with the help of enzymes, and the correct answer is digestive tissue.
• 😀 Question 16 compares the aging process, described in Surah Yasin verse 68, to diseases like Alzheimer's, as aging involves a return to a weak state, similar to the cognitive decline seen in Alzheimer's disease.

Q & A

What is the scientific explanation behind the event when Prophet Solomon's (alaihi salam) death was not known to the jinns until termites ate his stick?

The scientific explanation involves termites, whose intestines contain microorganisms (like protists and bacteria) that produce cellulase enzymes. These enzymes break down the cellulose in wood, allowing termites to digest it. This is how the animal, a termite, can digest the hard wood of Prophet Solomon's stick.

Why did Protozoa A outcompete Protozoa C in the algae culture?

Protozoa A replicated faster, growing its population more quickly than Protozoa C. As a result, Protozoa A consumed more algae, leading to resource depletion and outcompeting Protozoa C, which ultimately led to the decline of Protozoa C's population.

How does listening to the Qur'an affect the brain and hormone levels in the body?

Listening to the Qur'an increases alpha waves in the brain, which induces a sense of calm. This calming effect reduces the production of stress hormones, especially cortisol, by the adrenal glands, contributing to mental peace.

What is the role of the adrenal gland when a person experiences calmness from listening to the Qur'an?

When a person experiences calmness, the adrenal glands reduce the production of cortisol, a stress hormone. This reduction in cortisol helps promote a peaceful state of mind, which is linked to the calming effect of listening to the Qur'an.

Which tissue in bees is responsible for the production of honey?

The digestive tissue of the bee is responsible for honey production. The worker bees collect nectar, which is processed in the digestive system of house bees and turned into honey, stored in the honeycomb until it ripens.

What is the importance of the cellulase enzyme in termites' digestion of wood?

Cellulase enzymes, produced by microorganisms in termites' digestive systems, are crucial for breaking down cellulose in wood. This allows termites to digest wood, which is otherwise difficult to process due to its high cellulose content.

What happens to the population of Protozoa C over time in the algae culture scenario?

Over time, as Protozoa A outcompetes Protozoa C for algae, Protozoa C's population will decrease, potentially leading to its extinction in the culture due to resource depletion.

Which organ is involved in the release of cortisol during stress, and how is this affected by listening to the Qur'an?

The adrenal glands are responsible for the release of cortisol during stress. Listening to the Qur'an leads to a decrease in cortisol release, as the calming effect reduces stress hormones and helps bring about a peaceful state of mind.

What are the stages involved in the process of honey production in bees?

The process involves worker bees collecting nectar, which is then passed to house bees. These house bees process the nectar in their digestive system, using enzymes to convert it into honey, which is stored in the honeycomb until it ripens by losing excess water content.

Which disease is most closely related to the concept of aging and cognitive decline as described in Surah Yasin?

Alzheimer's disease is the most closely related to the concept of aging and cognitive decline described in Surah Yasin. This disease involves a progressive loss of brain function and dementia, which aligns with the idea of humans returning to a weak, cognitive state as they age.
