Cells
What type of cells are you made of?
Eukaryotic Cells!
According to cell theory, which of the following is the fundamental unit of structure and function in all known living organisms?
Cell
Recessive alleles are represented with a…
lower case letter
Evolution is:
A change in the inherited traits of a population of organisms over time.
What are the reactants for photosynthesis?
Water, Carbon Dioxide, and Sunlight
Where is DNA replicated during the cell cycle?
Nucleus
How many chromosomes do human somatic (body) cells have?
46
Natural selection is:
A. the evolution of the strongest organisms to be even stronger.
B. the evolution of the environment an organism lives in.
C. when nature selects the best traits for an organism.
D. the evolutionary process in which organisms best suited to their environment are more likely to survive and pass on their traits to future generations.
What structures are unique to eukaryotic cells? List at least 3!
Nucleus, Mitochondria, Chloroplasts, Golgi Apparatus, Rough/Smooth Endoplasmic Reticulum, etc.
Do plants have mitochondria? Why or why not?
Yes, because they still need energy from the sugar that the chloroplasts make.
A human with the genotype XX is generally…
Female
Artificial Selection is:
A type of biological evolution where humans choose which organisms survive and reproduce, a process known as selective breeding.
Name (at least) 3 principles of the Cell Theory:
Composed of 1 or more cells (Unit 1: Cells)
Reproduce using DNA (Unit 2: Heredity)
Can evolve as groups (Unit 3: Evolution)
Obtain energy from the environment
Sense and respond to their external environment
Sense and respond to their internal environment (Maintain Homeostasis)
What do our cells need to do to make a baby with 46 chromosomes if combining the parent’s cells would lead to 92 chromosomes?
Meiosis
List the order of steps of protein synthesis:
1. DNA is Transcribed into RNA
2. RNA is Translated in Protein
Define and give an example of coevolution
When two species evolve together. (Butterflies & Flowers, Wolves & Deer, Clownfish & Anemone, etc.)
List the steps of the Cell Cycle (ATCMP) and draw 1 of your choosing.
Prophase (Pre), Metaphase (Middle), Anaphase (Away), Telophase (Two), Cytokinesis
According to the principles of cell theory, why would a rock not be considered a living thing? (list 2)
Composed of 1 or more cells (Unit 1: Cells)
Reproduce using DNA (Unit 2: Heredity)
Can evolve as groups (Unit 3: Evolution)
Obtain energy from the environment
Sense and respond to their external environment
Sense and respond to their internal environment (Maintain Homeostasis)
If an organism is said to be a hybrid or have both alleles for a gene, that means they are…?
Heterozygous
List the six pieces of evidence that support evolution:
1. Direct observation of evolution through artificial selection
2. Fossil Evidence
3. Shared characteristics among living organisms
4. Similarities and differences in DNA
5. Biogeographic evidence
6. Common patterns of embryonic development
