How is the number of chromosomes in a human sex cell different from the number in a human body cell?
A sex cell has 23 chromosomes and a body cell has 46.
Dante wants to match the types of cells with how they are produced. Which choice correctly pairs a type of cell with how it is produced?

body cell is made by → mitosis in females


sperm cell is made by → mitosis in males


egg cell is made by → meiosis in males



body cell is made by → mitosis in females
The sperm is a human cell. What type of cell is this?
a reproductive cell made from meiosis
What does meiosis create?
reproductive (or sex) cells

Which of these choices is a made from the process of mitosis?

skin cell
Which of these choices is NOT a reason for mitosis taking place in a multicellular organism?



growth


repairing wounds


making sex cells

making sex cells
During a lab experiment, Rahul looks at six unlabeled slides showing different stages of the cell cycle. The teacher asks Rahul to place the slides in order, starting with interphase. In what order should Rahul place the slides?
interphase → prophase → metaphase → anaphase → telophase
Interphase is the longest stage in the life cycle of a cell. What occurs during this stage?
the cell grows and does its job
Which of these phases of mitosis takes place first?
prophase
Select the best description of a chromosome.
tightly wound DNA that is ready for cell division
Which of these statements is true of asexual reproduction?


It produces offspring genetically identical to each other and requires one parent.




It produces offspring genetically identical to each other and requires two parents.




It produces offspring genetically different from each other and requires one parent.

It produces offspring genetically identical to each other and requires one parent.
A small, aquatic animal is called a hydra is reproducing. Which term best describes this process?
budding
Which type of reproduction involves two parents and results in offspring that are not genetically identical to either parent?
sexual reproduction
In what way are the processes of sexual and asexual reproduction alike?
Both produce offspring.
Which reason BEST explains why reproduction is necessary?
The survival of every species depends on the ability of organisms to reproduce.
A group of scientists test three different types of cells – muscle cells, nerve cells, and skin cells – to find out which cell type goes through the steps of mitosis the fastest. The scientists time 100 cell divisions for each type of cell. The temperature and amount of light is the same for all of the cells. What is one controlled variable in this investigation?
temperature
