Draw a picture of DNA
|
|
|
What is a nucleotide?
|
A subunit of DNA or RNA made up of a sugar, a phosphate and a base.
|
|
What makes everyone's DNA unique? (Different from each other?)
|
The order of the bases.
|
|
In the process of making proteins, what carries the code to tell your cells what amino acids to join together?
|
mRNA
|
|
What does transfer RNA do?
|
It carries amino acids to the ribosome to make proteins.
|
|
What is made in the process of replication?
|
DNA
|
|
Describe DNA
|
Double stranded
Shaped like a twisted ladder Made of deoxyribose sugar Has four bases - T, A, G, C |
|
In what way is RNA different from DNA?
|
Is single stranded
Has ribose sugar. Has uracil instead of thymine |
|
Which bases pair together?
|
A - T , G - C Except in RNA, A would pair with U
|
|
Create a complement mRNA strand for the DNA strand shown
TAC GGT CGA |
AUG CCA GCU
|
|
How are traits passes from parents to offspring?
|
Through genes - usually in pairs, one from each parent. They can be dominant or recessive.
|
|
What is meant by the word phenotype?
|
What you physically look like.
|
|
The gene combination that determines your phenotype is called?
|
Your genotype - there are 3 genotypes, homozygous dominant, heterozygous and homozygous recessive.
|
|
How could a child get a genetic disorder if neither parent has the disease?
|
If it was caused by recessive alleles and both parents were carriers. The child could inherit a recessive allele from each parent.
|
|
What do you call this genotype? TT
|
Homozygous dominant
|
|
What do you call this genotype? Tt
|
Heterozygous
|
|
What do you call this genotype? tt
|
homozygous recessive
|
|
Make a punnett square crossing a Yy pea plant with a yy plant. If Yellow is dominant, how many of the offspring will be green? What is the phenotype ratio?
|
2 will be green. The phenotype ratio will be 2:2
|
|
Make a punnett square crossing a Blue Bb chicken with a Bb chicken. What will be the genotype ratio?
|
1 BB: 2 Bb: 1 bb
|
|
Traits related to the X or Y chromosome are called?
|
Sex-linked
|
|
What do you call the picture of the chromosomes shown?
|
a karyotype
|
|
What are the 4 possible human blood types?
|
A, B. AB and O
|
|
Define natural selection.
|
Survival of the best adapted organisms
|
|
What causes evolution?
|
natural selection
|
|
How do you know if two organisms are in the same species?
|
They can breed together and produce fertile offspring.
|
|
Define evolution
|
Change in organisms over time
|
|
What is the function of the digestive system?
|
To obtain nutrients from food
|
|
What is the function of the respiratory system?
|
To get oxygen to your cells
|
|
What is the function of the nervous system?
|
To send messages through the body
|
|
Name the major organs of the digestive system.
|
mouth, esophagus, stomach, pancreas, liver, small intestine.
|
|
How does genetic variation help a species survive?
|
By increasing chances of survival through diversity.
|
|
Due to misuse and overuse of antibiotics, bacteria are becoming resistant to many common antibiotics. (This means they are no longer being killed by the antibiotics.) What would this be an example of?
|
The bacteria are evolving
|
|
If you remove the sparrowhawk from this food chain, what will happen to the blue bird population?
|
It will increase
|
|
Who is the producer in the food chain?
|
The Holly
|
|
Is the producer an autotroph, heterotroph, consumer, decomposer, carnivore, herbivore or omnivore. Why?
|
It is an autotroph because it can photosynthesis and make its own food.
|
|
Is the leaf minor an autotroph, heterotroph, consumer, decomposer, carnivore, herbivore or omnivore? Why?
|
It is a first level consumer because it is eating a producer. It is a heterotroph because it has to consume its food. It is a herbivore because it is not eating meat.
|
|
Give an example of an omnivore.
|
A dog. It eats both meat and plants.
|
|
Who is the Father of Genetics?
|
Gregor Mendel
|
|
Who developed the Theory of Evolution?
|
Charles Darwin
|
|
Who discovered the shape of DNA?
|
Watson & Crick
|
|
Who developed binomial nomenclature?
|
Carolus Linnaeus
|
|
What are the 3 major biomes that cover the united states? Which one is Michigan in?
|
Temperate Forest, Grassland and Desert. Michigan is in a Temperate Forest.
|
|
What is the primary source of energy for a food chain?
|
The sun
|
|
What is a biotic factor? Give some examples.
|
Any living thing in an organism's habitat that has an impact on is life. Plant life, predators, food sources.
|
|
What is an abiotic factor? Give some examples.
|
Any non-living thing in an organism's habitat that has an impact on its life. Water, temperature, sunlight, humidity, wind, rocks, minerals.
