Genetics
What does the nucleus do?
Stores genetic information (DNA) and acts as the control center of the cell; where DNA replication and transcription occur.
what does genotype mean?
Genotype is the genes of an organism
What is an adaptation?
An adaptation is a change or the process of change by which an organism or species becomes better suited to its environment.
what causes artificial selection?
artificial selection is caused by human technology that has changed the inheritance of a desired trait in an organism.
What is a fossil?
Preserved remains or traces of animals, plants, and other organism from the remote past.
What is power house of cells called?
Mitochondria
what are phenotypes?
Phenotypes are the physical appearance of a trait in an organism.
What is behavioral adaptations?
behavioral adaptations is something the animal does in order to survive in the environment the animal lives in. It's an action not a part of their body.
what is selective breeding?
The process of changing a population over time by selecting for desired genetic traits.
If a rock layer is at the bottom it is the what?
The rock layer is the oldest rock layer.
What is mirosis?
The process where a single cell divides into two identical daughter cells.
What would you use when you are using Homozygous dominant and Homozygous recessive?
TT Homozygous dominant
tt Homozygous recessive
what is structural adaptation?
structural adaptations are physical traits that allow animals to survive in the environment they live in. structural adaptation is also a part of the animal's body or structure.
What is artificial selection?
When humans choose traits and breed organisms for those traits.
What is one type of fossilization?
permineralization, molds and casts, compression, and preserved remains
What cell does meiosis occur in?
The germ cell
what is Heterozygous and what do you use to represent it?
Heterozygous is different alleles
Tt
What is genetic drift
Genetic drift refers to the random fluctuations in the frequency of alleles inside a population over successive generations.
what are GMO advantages?
being insect resistant, being weed resistant,using less chemicals (herbicides/insecticides, Soil is preserved Drought resistant, increase consumer purchasing due to taste/cost,increase nutrition, and faster growth
What is extrusion?
a manufacturing process where a material, often plastic or metal, is forced through a shaped opening (a die) to create a product with a specific cross-sectional profile.
what is the difference between a plant and animal cell?
Plant cells have a cell wall in addition to a cell membrane, whereas animal cells have only a cell membrane.
what are punnett squares used for?
They are used to predict the genetic combination of traits of offspring.
what is natural selection?
Natural selection is the process through which populations of living organisms adapt to change.
What are GMO disadvantages?
unsure of long term effects on humans (allergies),could decrease crop diversity,could have long term effects on soil, and could be more prone to mutations.
What is intrusion?
the act of intruding or the state of being intruded.
