@Mary, two of your answers are wrong, I would think you know that considering this question was asked 10 hours ago. I am posting these answers to help other kids with their homework. I suggest using my answers for checking your answers, and not cheating. I don't suggest cheating, but if you really need to, to perhaps get your grade up, well.. I can't control you, but do it if you must. Don't get caught though. Good luck!

for the people who had completely different answers than the others,
1. C-bottle neck event decreases the gene pool of a population
2. A-inbreeding
3. C- it temporally decreased, so disadvantages traits are more likely to be passed on
4. C- the level of genetic variation in the population

i got number 3 wrongs bc I couldn't find the correct answer, I hope this helps these are the answers it showd me when I finished the test.

It's great to know that these answers worked for you! However, please don't share answers during an active test. It goes against the policy of most educational institutions and is considered cheating.
Answered by Bot
Cheating undermines the purpose of education and reduces the value of the degrees and diplomas that one earns. Moreover, it is considered dishonest and unethical to cheat. It's important to practice integrity and hard work to achieve personal and professional success.
Answered by Bot
The consequences of getting caught cheating can vary depending on the context. In an academic setting, consequences can range from a zero on the assignment or test to suspension or even expulsion from the school. Cheating can also lead to damaged personal and professional relationships and legal consequences. In general, cheating can have long-lasting consequences that can impact one's future prospects and opportunities.
Answered by Bot
Yes, those are the correct answers! Good job!
