Mitosis is a type of cell division that results in two daughter cells that have the same number and kind of chromosomes. Meiosis happens when it's time to reproduce an organism, meanwhile it only has one division.
What is the difference between meiosis and mitosis?
100
Fertilization is the joining of the sperm and the egg.
What is exactly fertilization?
100
One of the main disadvantages of a asexual reproduction is limited genetic variation because the organisms will turn out identical to it's parent.
What is one of the main disadvantages of a asexual reproduction?
100
Genetically identical No fertilisation Quick method of reproduction
What is one example of a characteristic that an asexual organism would inhairit?
200
The four steps of mitosis are Interphase, Prophase, Metaphase, Anaphase, and Telophase.
What is the four steps of mitosis?
200
External fertilization is when the sperm and egg are joined outside of the body. Internal fertilization is when the sperm and egg are joined inside of the body.
What is the difference between external and internal fertilization?
200
Saves time and energy, mobility is not required, numerous offspring can be produced at minimal cost to the parent, populations grow quickly, and offspring are genetically identical to parent.
What is an advantage of an asexual reproduction that doesn't compare to sexual reproduction?
200
They say that they have won the "genetic lottery".
What is it called when a species's genes have allowed them to have an advantage to able to adapt to change?
300
In the first division the number of cells in doubled but the number of chromosomes is not. This then makes half as many chromosomes per cell. The second divison is a lot like mitosis, and the number of chromosomes do not get reduced.
What is the reason why there are two stages of meiosis?
300
An example of an animal who fertilizes externally would be a female fish. An example of an animal who fertilizes internally would be a dog.
What is two examples of animals who fertilize externally and internally?
300
No adaptation and prone to extinction.
What is two more disadvantages of asexual reproduction?
300
Genetic diversity can be permanently lost.
What is possible if the population of these survivors becomes too small?
400
Prophase, Metaphase, Anaphase, and Telophase.
What is the first half of meiosis's four stages?
400
Budding, Spores, Fragmentation, Vegitive Reproduction and Binary Fisson
What is one way for an asexual organism to reproduce?
400
Permits Variation, Allows Removal of Bad Genes, Increases Diversity, Multiple Unique Offspring and Increased Survivability.
What is the advantages of sexual reproduction?
400
Allows Removal Of Bad Genes Multiple Unique Offspring Increased Survivability
What is one example of why variation is so important for the survival of a species?
500
Cytokinesis is responsible for the division of four haploid cells. That are now gametes.
What is the meaning of the word Cytokinesis?
500
The meaning of the word budding is (of a plant) having or developing buds. The process of budding is where an offspring grows out of the body of a parent. So yes, I would say that the definition helps to understand the word as the offspring is developing.
What is the meaning of the word budding? What is it and how does it relate to asexual reproduction?
500
It's sexual reproduction! The reason for this is because you need two parents to provide half the genetic code of the gamete.
What is the reproductive way that involves gametes?
500
This again leads to much more variation in population and increased diversity.
What is unique about the comboination of genes, half from each parent?
