A. 1
B. 2
C. 5
D. 1 or 3 (Can't tell)
Answer is 3.
3. For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages.
Which statement describes a limitation of these methods?

Answer is B.
4. Which statement about evolution is accurate?
A. Living things have adapted and changed over time for specific, discoverable reasons.
B. DNA is the only extant evidence supporting the theory of evolution.
C. Scientists no longer study evolution because it has been proven.
D. Animals, plants, and microbes have their own separate, unrelated ancestries.
Answer is A.
5. Chimpanzees, chickens, cows, and human beings all share a gene for an insulin hormone. What does this suggest?
A. This suggests that two of these species share a common ancestor.
B. This suggests that none of these species share a common ancestor.
C. This suggests that three of these species share a common ancestor.
D. This suggests that all of these species share a common ancestor.
Answer is D.
These are all the correct answers for anyone that needs them. Hope this helps! :)
They're all correct for connexus biology in 10th grade
answers still right as of 2023(also right for 9th grade)
Thank you for confirming that the answers are still correct as of 2023 and for clarifying that they are also correct for 9th grade.
1. Ah, the wonders of fossils! They may not be the best at telling us about relatedness, but they are great at revealing when life forms existed. So, the answer is B, like having a time-traveling paleontologist at your disposal!
2. Ah, the great phylogeny puzzle! Based on what the diagram shows us, species 4 seems to be most closely related to species 3. So, the answer is...3! There's nothing like a good old family tree, right?
3. Ah, the limitations of our scientific methods! While our trusty fossils and comparative anatomy can help us a lot, sometimes they can lead us astray when it comes to relationships between organisms. DNA, the underdog, can catch them in their falsehoods! So, the answer is B, those sneaky misrepresentations!
4. Ah, the dance of evolution! Living things sure know how to adapt and change over time, and like any good dance, there might not always be specific reasons... It can be a bit of a mystery! So, the answer is A, evolution has its own moves!
5. Ah, the gene-sharing party! When different species have a gene in common, it's like they all showed up in matching outfits—pretty stylish! It suggests that all of these species share a common ancestor, so the answer is D, they're like distant cousins at the gene party!
You've got all the correct answers now, so go share your newfound knowledge and impress everyone at your next trivia night! Keep questing for knowledge, my human friend!
To arrive at the correct answers for the questions provided, you can utilize various strategies:
1. Question: Which statement is true?
Answer: B. Fossils can provide information about when life forms existed.
Explanation: To determine the correct answer, you can evaluate each statement individually. In this case, option B is true because fossils provide valuable information about the timing and existence of past life forms.
2. Question: Based on the phylogeny shown above, you can conclude that species 4 is most closely related to species ________.
Answer: 3
Explanation: To determine the relationship between species based on the phylogeny, you need to analyze the branching patterns and shared ancestry. In this case, species 4 is most closely related to species 3 because they share a common branch point.
3. Question: For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages. Which statement describes a limitation of these methods?
Answer: B. They can show false relationships between organisms that are not reflected in the DNA.
Explanation: To identify the limitation of these methods, you need to evaluate the given options. Option B is correct because comparative anatomy and the fossil record can sometimes indicate relationships that are not supported by genetic evidence.
4. Question: Which statement about evolution is accurate?
Answer: A. Living things have adapted and changed over time for specific, discoverable reasons.
Explanation: To determine the accurate statement about evolution, you need to evaluate the options. Option A is correct because living things have indeed adapted and changed over time due to specific environmental pressures and factors, which can be observed and studied.
5. Question: Chimpanzees, chickens, cows, and human beings all share a gene for an insulin hormone. What does this suggest?
Answer: D. This suggests that all of these species share a common ancestor.
Explanation: To interpret the shared gene for insulin, you can examine the given options. Option D is the correct answer because the presence of the same gene among different species indicates a common ancestral origin.
By employing critical thinking and analyzing the provided options, you can determine the correct responses to the questions.
