Which of these statements is false? O In humans, each of the 22 maternal autosomes has a homologous paternal chromosome. O In humans, the 23rd pair, the sex chromosomes, determines whether the person is female (XX) or male (XY). Single, haploid (n) sets of chromosomes in ovum and sperm unite during fertilization, forming a diploid (2n), single-celled zygote. O At sexual maturity, ovaries and testes produce diploid gametes by meiosis. O Sexual life cycles differ with respect to the relative timing of meiosis and fertilization.

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
