Genetics and the environment both play roles in cell differentiation. which is the best example of an environmental factor? the cells of a chicken embryo divide to form three layers: the ectoderm, mesoderm, and endoderm during meiosis, a single cell divides to form four gametes with half the number of chromosomes that somatic cells have. the terminal bud on a runner of a strawberry plant begins growing roots when it contacts the ground. cambium cells in the trunk of an apple tree form rings of xylem and phloem annually.

Which could be a pathway of food through an ecosystem

Which feature would you expect to find in a population in which sexual selection depends on male competition?

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.
