| Question | Answer |
|---|---|
| if n is haploid and 2n is diploid, write the equation for fertilization | n+n= 2n |
| when an organism grows a "bud" or branch that breaks off and becomes a separate organism, what type of asexual reproduction is this? | budding |
| how could you tell if single celled organisms are reproducing | you will get more single celled organisms |
| why is a control group used in an experiment | it is what you compare the results to |
| why do some adaptations get passed on to offspring | they were beneficial to survival and reproduction |
| what must occur for evolution to continue | sexual reproduction |
| how are alleles passed on to offspring by parents during sexual reproduction | each passes half of their alleles randomly |
| what do all plant cells contain | cell walls and chloroplasts |
| what is a change in the genetic code called | mutation |
| a diploid cell has on set of what from each parent | chromosomes |
| what type of reproduction involves egg and sperm | sexual |
| what is natural selection and how does it relate to reproduction rate | leads to the production of more offspring |
| in animals sexual reproduction begins with these two cells | egg and sperm |
| when one egg is fertilized by a sperm, what is the fertilized egg now called | zygote |
| does locomotion help or hinder reproductive success | helps |
| how does an offspring created through asexual reproduction compare genetically to the parent | it is identical |
| which cell organelle controls the cell | nucleus |
| when two gametes unite to form a zygote what type of reproduction is occurring | sexual |
| asexual reproduction of a diploid cell results in what | two diploid cells (2n reproducing asexually is splitting into two identical cells- 2n in each) |
| how do butterflies reproduce | sexually by laying eggs |
| what process requires light in plants | photosynthesis |
