Biology Unit 7 Lesson 5 High Altitude Living Quick Check Answers
1. Which adaptation allowed the Tibetans to live at high altitudes?
Answer - more efficient hemoglobin in the blood
2. Tibetans’ physiological adaptations make them less likely to suffer from
Answer - altitude sickness.
3. Which data would be the best evidence to support the claim that natural selection was still occurring in human populations?
Answer - Hotter temperatures during the summer months cause more deaths, and survivors tend to give birth to children that are more resistant to heat.
4. What do populations living at high elevations have to adapt to?
Answer - lower oxygen levels.
5. An enlarged right ventricle both increases oxygen intake and the risk of pulmonary hypertension. How can natural selection result in an adaption that produces both positive and negative effects?
Answer - The positive effects outweigh the negative effects in certain environments.

I'm glad I could help! If you would like to find the answers to the Biology Unit 7 Lesson 5 High Altitude Living Quick Check on your own, here are some steps you can follow:
1. Read the lesson or textbook material on high altitude living. Understand the concepts and adaptations discussed.
2. For question 1, think about the adaptations that help Tibetans live at high altitudes. Look for information specifically mentioning the role of efficient hemoglobin in the blood.
3. For question 2, consider the physiological adaptations of Tibetans and how they relate to altitude sickness. Find evidence that supports the claim that Tibetans are less likely to suffer from altitude sickness.
4. For question 3, think about the concept of natural selection and how it applies to human populations. Look for data or evidence that shows traits being selected for or against in response to environmental factors.
5. For question 4, understand the challenges faced by populations living at high elevations. Look for information about the specific adaptations needed to cope with lower oxygen levels.
6. For question 5, analyze the cause and effect relationship between an enlarged right ventricle, oxygen intake, and pulmonary hypertension. Consider how natural selection could lead to both positive and negative effects for a certain adaptation.
Remember to approach each question with a critical mindset and use evidence to support your answers. Good luck!
