What process creates sexually reproducing cells?
meiosis
How many parents are needed for asexual reproduction?
One parent.
What are the two main types of cell division?
Mitosis and Meiosis.
What is the purpose of the menstrual cycle?
To prepare women's bodies for pregnancy.
What is a piece of DNA called?
A gene.
How many parents are needed for sexual Reproduction?
Two parents.
What is the offspring of asexual reproduction compared to its parent.
Genetically identical.
What is the purpose of mitosis?
To create body cells/growth, repair of pre-existing cells.
On what day of the menstrual cycle does ovulation occur?
Ovulation occurs on day 14 of the menstrual cycle.
Before cell division.
What are sexually reproducing cells called?
Gametes (Sperm and Egg cells).
What is an advantage of asexual reproduction?
no mate required/ quick/ saves energy/ no disease exposure
How many daughter cells are created in meiosis?
Four daughter cells.
Where does fertilization occur?
In the females fallopian tubes.
What is the function of DNA?
What is an advantage of sexual Reproduction?
Offspring has genetic variation.
What happens in the metaphase in mitosis?
Chromosomes line up at the middle.
What is the difference between the daughter cells chromosomes in Mitosis and Meiosis?
Mitosis daughter cells end with diploid(full/46) chromosomes, and Meiosis daughter cells end with haploid(half/23 ) chromosomes.
The testes.
What do genes code for?
Proteins that determine characteristic traits.
Why is there a larger percent of sexually reproduced organisms?
Because they are less likely to face extinction.
How many offsprings are the result of mitosis?
(Two) new identical daughter cells are formed from mitosis.
How does the DNA of mitosis derived cells compare to the DNA of meiosis derived cells?
Mitosis derived cells are genetically identical and Meiosis derived cells are genetically different.
What is testosterone responsible for?
The stimulation of sperm production, and the stimulation of puberty.
