Choose the best experimental design to test the question “does the gender of mice affect the time it takes to learn mazes? ” time six male mice and six female mice in the same maze; reward the male mice with fruit when they complete the maze, and reward the female mice with grains when they complete the maze. time six male mice and six female mice in the same maze; reward both male and female mice with fruit when they complete the maze. time six male mice in one maze and six female mice in a second similar maze; reward both male and female mice with cheese when they complete the maze. time each mouse in a different maze; reward the male mice with bread when they complete the maze, and reward the female mice with cheese when they complete the maze.

Option B

Explanation:

A experiment is conducted in order to test the hypothesis that Is the gender of mice responsible for the time taken by male and female mice to complete the mazes.

To test this hypothesis an experiment will be conducted in which six female mice and six male mice will be put into the same maze and the mice will be provided with a fruit as a reward just after they end the maze.

After performing the experiment in this way there will be a conclusion that whether the hypothesis is accepted or rejected.

hence, option B is correct

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
