What's What's the genotype of a heterozygous woman that has freckles?
|
Four Daughter cells.
How many Daughter cells do you end up with at the end of Meiosis 2?
|
The phases are interphase, prophase, metaphase, anaphase, and telophase.
What are the 5 steps in mitosis?
|
The first step of the scientific method is the "Question
What is the first step of an experiment?
|
4.6 billion years old
How old do Paleontologists believe the Earth is?
2015 years old 3.6 billion years old 4.6 billion years old 4.6 million years old |
|
HH,RR,FF,TT
Give an example of homozygous dominant genotype
|
Metaphase 2
When do chromosomes line up in a single file?
|
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells
What happens in the mitosis?
|
an educated guess to the scientific problem
Hypothesis
|
all of the above
Why is the fossil record incomplete?
fossils get eroded away over time most organisms never became fossils scavengers and decomposers eat them too quickly all of the above |
|
Deoxyribonucleic Acid(DNA)
What does DNA stand for?
|
A sequence of DNA that codes for a specific trait
What is a gene?
|
2 genetically identical daughter cells
Mitosis results in the formation of what?
|
Scientific Question
Which helmet (football, baseball, or bike) will best protect the melon head?
|
In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
What does the Law of Superposition state?
Each sedimentary layer of rock represents 1,000 years of Earth’s age, much like the rings of a tree. In undisturbed layers of sedimentary rock, the upper rock layers are older than the lower rock layers. In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Rocks that form near volcanoes are older than surrounding rock. |
|
Gametes must join with another gamete to form a new individual organism in fertilization
Why is it important for gametes to have only half the DNA of an adult?
|
Cytoplasm divides and 2 daughter cells are formed
What happens in Telophase 1?
|
d) cell plate
Which of the following products is NOT made during interphase?
a) RNA b) proteins c) organelles d) cell plate |
Problem, Research, Hypothesis, Experiment, Results, Conclusion
Name the steps to the scientific process. All 6

Dinosaur bone
Law of Superposition - older fossils are in the lower layers
Which would be older, a dinosaur bone found in the bottom rock layer or a mammal bone found in the middle rock layer?
|

Draw a Punnett square and cross a homozygous recessive mom with a pure dominant dad.
|
four haploid cells
What is final product of meiosis?
|
Prophase-cell begins breaking down some structures and creating others, preparing for the division of chromosomes
Metaphase: chromosomes line up along the metaphase plate (centre of the cell) Anaphase: sister chromatids are pulled to opposite poles of the cell Telophase: nuclear envelope reforms,chromosomes unfold into chromatin
What happens in each steps in mitosis?
|
A series of steps followed to solve problems
I was incorrect, the football helmet best protected my melon head. There was only 1 crack in the melon measuring 1/2 inch.
What is scientific process?
Which one is the conclusion: I was incorrect, the football helmet best protected my melon head. There was only 1 crack in the melon measuring 1/2 inch. OR I measured the number of cracks in the melon head and the size of the cracks in the melon head. |
relative dating
Which type of dating method can be used on rock layers by applying the Law of Superposition?
relative dating absolute dating radioactive dating radiometric dating |
