Question

Quizplus · Accepted Answer

Each person is made up of cells, and these cells contain 23 matching pairs of chromosomes. Thus, option B is the correct choice. Option A is incorrect because while humans do have trillions of cells, the particular number of cells is not specified in the statement. Option C is incorrect because while humans do have matching pairs of chromosomes, chromosomes are not what comprise individuals. Option D is also incorrect because while cells and chromosomes are both components of individuals, the statement specifies that individuals are made up of cells and chromosomes are contained within those cells, so the correct answer choice would specifically mention cells and chromosomes as separate entities.
