Hello everyone here we have a question asking which of the following describes natural selection. Natural selection is the differential survival and reproduction among individuals within a population due to different traits. The individuals with advantages traits get to go on and reproduce and continues having these traits and passing on these traits while the individuals without these traits can't adapt and don't get to go on to reproduce. So the advantages traits stay while the disadvantages traits are eventually eliminated. So we have a individuals in the population vary and this variation can be advantages for their survival. This is correct. Be all individuals in the population are jian typically and then a typically identical. We know that this is incorrect. See advantages traits are easily swept off by natural selection. Advantages traits generally stay in a population because those with advantages traits get to go on to reproduce. So C. Is incorrect. D the number of offspring will remain constant regardless of any environmental change. This is incorrect. So our answer here is a individuals in the population vary and this variation can be advantageous for their survival. Thank you for watching. Bye.
