Epigenetics & Frozen Frogs Trivia Quiz

The studies suggest that as twins age, their epigenetic differences accumulate. This means that over time, the epigenetic markers in their DNA become more distinct from each other. Additionally, twins with different lifestyles have different epigenetic expressions, indicating that factors such as diet, exercise, and smoking can influence these markers. Therefore, it can be concluded that all of the above statements are supported by the studies.

Identical twins come from the same egg, which means they share the same genes. They are essentially clones of one another because they have the same genetic makeup. Therefore, all of the above statements are correct.

When the frog is frozen, it enters a state of suspended animation where all bodily functions cease. This includes breathing, kidney function, and heartbeat. The freezing temperatures slow down or stop the metabolic processes, essentially putting the frog in a dormant state. Therefore, the correct answer is that there are no bodily functions at all when the frog is frozen.

The comparison between a gene and a computer suggests that a gene contains the instructions or code for a specific function, just like a computer. Therefore, an epigenome, which refers to the chemical modifications of DNA that can influence gene expression, can be compared to computer software. Just as software controls the functioning of a computer, the epigenome controls the expression of genes and regulates various cellular processes.

The correct answer is fat...thin. The explanation for this answer is that the two mice are described as "identical" in all respects. This means that they are exactly the same except for the fact that one is fat and the other is thin. Therefore, the answer fat...thin fits the given description.

A normal mouse weighs approximately 30 grams.

The frozen frog can take as long as 10 hours to spontaneously resume bodily function. This suggests that the freezing process temporarily halts the frog's bodily functions, but after a certain period of time, the frog is able to thaw and regain normal functioning. It is likely that the frog's physiological processes slow down significantly during freezing and gradually return to normal as it thaws.

North American wood frogs have the unique ability to survive being frozen solid. During the winter, they produce a natural antifreeze-like substance that protects their cells from freezing and forming ice crystals. As the temperature drops, their body gradually freezes, and their heart and breathing stop. However, they are able to revive themselves once the temperature rises, with their cells thawing and resuming their normal functions. This remarkable adaptation allows them to survive in cold climates where other amphibians would not be able to endure.

The correct answer is "l'amour" which means love in French. This suggests that the first thing on a freshly thawed frog's mind is finding a mate or engaging in reproductive activities. This is a common behavior in many species where the primary instinct after survival is to reproduce and ensure the continuation of their species.

When the frog begins to freeze, it floods its circulatory system with a special type of "antifreeze" in the form of sugar. This is because sugar acts as a cryoprotectant, preventing ice crystals from forming and damaging the frog's cells. By increasing the concentration of sugar in its blood, the frog is able to lower the freezing point of its bodily fluids, allowing it to survive in freezing temperatures.
