Biology Unit 7 Lesson 10 Natural Selection Practice Answers
1. What is the definition of adaptive radiation?
Answer - when an ancestor species rapidly splits into different descendants due to environmental pressures
2. In population genetics, F=q refers to
Answer - In population genetics, F=q refers to
3. __________ is/are used to describe that environmental factors influence an organism’s gene expression.
Answer - Epigenetics
4. The specific location of an allele is called a
Answer - locus.
5. What may cause two populations to develop different traits?
Answer - migration
6. Which other adaptation may be useful for living at high elevations?
Answer - more hair
7. Which major event led to the eventual adaptive radiation of Darwin’s finches from one common ancestor (i.e., what is the primary reason they evolved)?
Answer - differing availability and types of food resources
8. Bacteria are able to evolve easily, which is why antibiotic resistance is on the rise. Several factors contribute to the evolution of bacteria, except
Answer - they have the shortest genetic material, which makes them the fastest to replicate.
9. Which factor leads to genetic drift rather than natural selection?
Answer - Genetic variation is random and frequency changes each generation.
10. Which factor is abiotic?
Answer - decrease in sunlight
11. What is the difference between correlation and causation?
Answer - Correlation is a relationship between two variables, while causation is when an event or action happens and it appears to make another event or action happen.
12. How are correlation and causation similar?
Answer - They are both used to describe connections and influences between variables.

2: c. The recesive allele frequency in a population
And all the other answers were correct 😁👍🏽
What is the answer for number two
1. Well, adaptive radiation is like when one species goes "poof!" and suddenly there's a bunch of new species running around. It's like a family reunion where everyone brings their quirky traits.
2. Ah, F=q, the population genetics equation that keeps us all up at night. F apparently refers to "forces of nature" or maybe "frustration" because, honestly, who knows?
3. Epigenetics, the science of how the environment turns genes on and off. It's like genes are dancers and the environment is their DJ, controlling when they hit the dance floor. Let the genes boogie!
4. Locus, the fancy way of saying "Hey, allele, where are ya hanging out?" It's like gene geography, except instead of mountains and rivers, we're talking about chromosomes and genes.
5. Migration, the great diva of trait diversity. It's like when two populations decide they need some space, move to different neighborhoods, and suddenly they're shopping at different boutiques and sporting different hairstyles.
6. More hair, the ultimate high-altitude fashion statement. It's like wearing a cozy sweater all the time, except it's your own body hair. Talk about being a natural hipster.
7. Differing availability and types of food resources, the ultimate gourmet hotspots for Darwin's finches. It's like a buffet of different foods, and these finches were like, "Move aside, I'm trying everything on the menu!"
8. Bacteria evolving easily is like their secret talent. It's like they're the Usain Bolt of evolution, sprinting ahead of antibiotics. But hey, they totally skipped the class on "How to Share Nicely."
9. Genetic drift, the chaotic party where frequency changes are random and nobody knows how it will all end. It's like a game of musical chairs, and some alleles just aren't fast enough to snag a seat.
10. Decrease in sunlight, the abiotic factor that's like a dimmer switch for plants. It's like the sun's playing hide-and-seek with them, and they have to adapt to less light. Time to break out the night-vision goggles, plants!
11. Correlation, when two things like to hang out together. It's like peanut butter and jelly, always seen together, but not always causing the other to exist. So, correlation is kind of like friendship without the power dynamics.
12. Correlation and causation are like best buds. They're both about connecting the dots between variables. It's like when you see someone wearing a hat and sunglasses, and you guess they're trying to avoid sunburn. Sometimes it's a safe bet, but sometimes they just want to look cool.
Great! I'm glad I could help. If you have any more questions, feel free to ask.
To find the answers to these questions, you can use various resources. Here are the steps you can take:
1. Start by reviewing your biology textbook or any study materials provided by your teacher for Unit 7 Lesson 10, focusing on the topic of natural selection. Read and understand the relevant sections.
2. If you have access to an online learning platform or website associated with your biology course, check if there are any practice exercises or quizzes related to this lesson. This can help you reinforce your understanding and find the answers to the specific questions you have.
3. If you are still unable to find the answers, you can search for credible online resources or scientific websites that explain natural selection, population genetics, and other concepts mentioned in the questions.
4. Use keywords from each question to search for relevant information. For example, for question 1, you can search for "definition of adaptive radiation in biology." Look for reliable sources, such as educational websites or scientific articles, that can provide accurate explanations.
5. Read the information you find carefully and find the answer that matches the question. Take notes or highlight important points to help you remember the answer.
Remember, understanding the process of finding the answers is just as important as knowing the answers themselves. By following these steps, you can learn how to research and find information effectively, a crucial skill for any learner.
