What is the result of a new organism develops that has its own unique identity?
Chapter 4 Review
| Question | Answer |
|---|---|
| As a result of _______________, a new organism develops that has its own unique identity. | reproduction |
| An error made during the copying of DNA is called a ____________.? | mutation |
| A double spiral molecule with pairs of nitrogen bases? | DNA |
| What is in RNA but not in DNA? | uracil |
What is the result of meiosis?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
What is a type of reproduction when a new organism is produced that has hereditary material identical to the parent organism?
Chapter 8-Cell Reproduction Vocabulary
| A | B |
|---|---|
| chromosome | in a cell’s nucleus that contains hereditary material. |
| asexual reproduction | a type of reproduction in which a new organism is produced from one parent and has hereditary material identical to the parent organism. |
How these organisms grow develop and reproduce?
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent.
When a new organism is produced from one organism it is called?
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – “offspring” – are produced from their “parent” or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.
What process results in the formation of a zygote?
Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. This process ultimately leads to the formation of a diploid cell called a zygote. The zygote divides to form a blastocyst and, upon entering the uterus, implants in the endometrium, beginning pregnancy.
Which of the following is unique to meiosis?
Correct. Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
Which are produced as a result of meiosis *?
The result of meiosis is 4 gametes, or sex cells, that each contain half of the genetic information in the parent organism. A process in cell division during which the number of chromosomes decreases to half the original number.
How an organism creates new organisms that are similar to itself?
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – “offspring” – are produced from their “parent” or parents. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself.
What is the process by which organisms make new organisms?
reproduction, process by which organisms replicate themselves. In a general sense reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species.
Why do organisms differ in their methods of reproduction?
Organisms that reproduce through asexual reproduction tend to grow exponentially and rely on mutations for DNA variation, while those that reproduce sexually yield a smaller number of offspring, but have larger genetic variation.
