The nucleus
The jellylike "soup" that fills most of the cell
cytoplasm
Four animal mating behaviors

The three parts of the cell theory.
All organisms are made of cells
Cells are the basic unit of life
All cells come from the division of previously existing
Offspring of sexual reproduction have a better chance of survival because..
They have a variation of genetic material which allows the species to be able to adapt better

What is natural selection?
What are the four reasons cells undergo cell division (mitosis & meiosis)
replace old cells, for growth, repair damaged cells, and reproduction
What am I? I have cytoplasm and mitochondria but do not have a cell wall.
animal cell

sperm cells
Number of chromosomes in each human cell
46
What evidence supports the common ancestor theory? (name two)
comparative anatomy, embryology/ development, fossil record, and DNA analysis
Describe a trait that would benefit an organism's natural selection for reproduction but not natural selection for survival.
Answers can vary. Example: bright colored feathers are attractive to female birds but cause the male birds to stand out to predators.
