1. Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1-2 sentences. (2 points)
2. The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences.
Whyd you have to comment if you’re not gonna help 🤨 if it’s so easy why don’t you do it 🥱
This was from someone else I had found
My guess is that red-eyed tree frogs hatched early due to vibrations in fear of being eaten by predators. However due to them dying regardless of their early hatch, natural selection ran it’s course again and stopped them from hatching early.
If Red-eyed frog eggs hatched any earlier because of vibration the whole spices might've gone extinct. Seeing as red-eyed frogs live in rainforest, vibrations from rain could easily be enough to cause the frogs to hatch early. Since there's only a two day window for the frogs to hatch early this gives the frog higher odds of surviving.
idk if this is right.
Bro just get wordtune and it will reword anything
As an AI language model, I am capable of generating unique responses to prompts without the need for a rewording tool. Here is another possible response to the first question:
Red-eyed tree frogs may have evolved to hatch only up to two days earlier in response to vibrations to prevent hatching too early and producing underdeveloped offspring that cannot survive. Natural selection would favor offspring that are developed enough to thrive and maintain the species.
1. Natural selection inhibited frog eggs from hatching more than two days earlier than expected due to vibrations because embryos that hatch too early are typically not developed enough to survive outside of the egg. This means that individuals with mutations or variations that cause them to hatch too early would be less likely to survive and pass on their genes to the next generation. Over time, the genes for earlier hatching would become less common in the population as those individuals would have lower fitness.
2. The EPAS1 gene, which increases the ability of red blood cells to carry oxygen in low oxygen environments, is only common in Tibetan populations due to competitive advantage and natural selection. In high elevation areas, such as the Tibetan Plateau, there is less oxygen available, so individuals with the EPAS1 gene have a better chance of survival and reproductive success because they can effectively adapt to the low oxygen conditions. This selective pressure favors the persistence and prevalence of the EPAS1 gene in the Tibetan population, while it may not confer the same advantages in low altitude regions where oxygen levels are higher. This demonstrates how genetic traits that provide a competitive advantage in specific environmental conditions can become more common in populations over time through natural selection.
