AQA A LEVEL BIOLOGY Paper 1 2024 What is the function of the cell membrane? - ANS To control what enters and leaves the cell, acts as a barrier between the cell and its environment. What structural feature of the cell membrane allows substances to enter/leave? - ANS Partially permeable What is the fluid mosaic model? - ANS States that a membrane is a fluid structure (because phospholipids are constantly moving) with a "mosaic" of various proteins embedded in it Describe t...

Biology 1108 Unit 1 EXAM Questions and Answers 100% Pass The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: A)the number of occurrences of the allele. B)the number of occurrences of the allele divided by n. C)the actual value of n D)the number of occurrences of the allele divided by twice the number of individuals in the sample (2n). E)twice the number of occur...

ADVANCED PLACEMENT (AP) BIOLOGY: Identify Evolutionary Change Mechanisms 40 Questions Correctly Answered | 100% Rated Question 1 What conclusion did Darwin draw from the finches he observed at the Galapagos Islands? Possible Answers: Organisms will evolve in order to fill unoccupied niches in their environment. Finches will all live in the same area of a tree, regardless of species type. Birds reserve a herd mentality, and will aspire to remain similar in appearance to one another...

evolution - change in gene frequency in a population over time mechanism - a way for change to occur natural selection - a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits - proposed mechanism for evolutionary change variation is determined by - the environment heredity - passing of traits from parents to offspring reproductive success - successfully passing genes to next generation...

Are chimps or humans more genetically variable? - ️️chimps surprising because there are 300,000 chimps in the world and 7 billion humans Define natural selection. - ️️Individuals less suited to an environment are less likely to survive and less likely to reproduce, individuals more suited to the environment are more likely to survive and more likely to reproduce and leave their heritable traits to future generations, which produces the process of natural selection Describe capture of...
