7th grade Heredity
| Question | Answer |
|---|---|
| compared to the offspring produced by sexual reproduction, the offspring produced by asexual reproduction will be | more genetically uniform |
| when comparing the offspring of sexually and asexually reproducing organisms we would expect the genetic material of the sexually reproducing organisms to | show more variation |
| the offspring of an organism produced through sexual reproduction is always | different from its siblings |
| a potato that is covered with "eyes" or buds is buried in the soil. The eyes grow into new potato plants. What type of asexual reproduction is this? | vegetative propagation |
| A paramecium is a one celled organism that reproduces by splitting in half to become two new cells. What type of asexual reproduction is this? | binary fission |
| some animals such as hydras reproduce by budding. During budding a part of the hydra pinches off and forms an organism. Which of the following would be a characteristic of this kind of reproduction? | offspring are genetically identical to the parent |
| genes are located on an organisms | chromosomes |
| the primary function of the chromosome is to | store the genetic instructions needed to specify traits |
| the inherited traits of an organism are governed by | genes |
| heredity defines the passage of genetic material from | parent to offspring |
| genetic material is primarily responsible for | governing inherited traits |
| the smallest unit of life in plants are | cells |
| tissues working together to perform specialized functions are called | organs |
| sieve tube cells and companion cells work together to transport sugar and nutrients inside plants. Together sieve tube cells and companion cells form | a tissue |
| xylem tissue transports water inside plants. Xylem tissue is made up of | cells |
| which of the following examples best represents the levels of organization from least to most complex? | lungs -> lung tissue -> lung ->respiratory system -> human |
