Mice with brown fur will be less likely to pass on their genetic information.
Brown fur will become predominant.

i really need help
the answers are

helper is right!
You are wrong
is helper right?
@Anonymous the answer
What’s the answer I’m desperate 🧍🏼♀️
plz we need the answers
Sure! I would be happy to help you with your questions. Let's go through each question one by one:
1. Natural selection causes changes in (1 point)
The correct answer is phenotypes. Natural selection acts on the phenotypic variations within a population, favoring certain traits that provide a greater chance of survival and reproduction.
To get this answer, you need to understand the concept of natural selection. Natural selection is the process by which specific traits or variations that enhance an organism's chances of survival and reproduction become more prevalent in a population over time. It acts on the phenotype or the observable physical characteristics of an organism.
2. Which statement is accurate about natural selection? (1 point)
The correct statement is "Natural selection does not change the alleles an organism has."
To arrive at this answer, you should understand that alleles are different forms of a gene that occur at the same position, or locus, on a chromosome. Natural selection acts on individuals with certain traits rather than directly changing the alleles themselves.
3. Which mutation scenario will always lead to natural selection? (1 point)
The correct answer is "a mutation causes a specific advantage within the population."
To determine this, you should recognize that natural selection favors traits or variations that provide a specific advantage for survival and reproduction. A mutation that results in such a advantageous trait will likely be selected for, increasing its prevalence in the population over time.
4. Consider the following scenario:
There are variations in the fur color of mice. Some mice have white fur. Some have dark fur. Foxes more easily catch mice with white fur.
What will likely be a consequence of this scenario? (1 point)
The correct answer is "Mice with white fur will be more likely to survive and reproduce."
To arrive at this answer, you should apply the understanding that natural selection favors traits or variations that increase an organism's chance of survival and reproduction. In this scenario, mice with white fur are more easily caught by foxes, meaning they are less likely to survive and reproduce compared to mice with dark fur. Over time, this could result in an increased prevalence of mice with dark fur in the population.
5. What evolves during natural selection? (1 point)
The correct answer is "the proportion of different traits in a population."
To determine this, you should understand that natural selection acts on individuals with certain traits, favoring those that provide an advantage. As a result, the frequency or proportion of different traits within a population can change over time as traits that confer a survival and reproductive advantage become more prevalent.
I hope this explanation helps you understand the answers to the questions. Let me know if there's anything else you need assistance with!
