Ecosystems
What is carrying capacity?
The maximum population size of a species an environment can sustainably support over time.
What is a cladogram?
A model showing how closely related different species are to each other by showing a common ancestry.
Photosynthesis
What are the three components of DNA nucleotides.
Phosphate, sugar (ribose), and nitrogenous base.
Which cells do not have DNA?
Red blood cells
Name three limiting factors that impact carrying capacity.
-Water
-Food
-Competition
-Predators
-Space
-Disease
-Climate/weather
-Availability of mates
-Others at teacher discretion.
-Overproduction of offspring
-Competition
-Adaptation
-Variation
Which of the life processes converts glucose into energy?
Cellular respiration
What are the names of the four nitrogenous bases in DNA?
-Adenine
-Thymine
-Guanine
-Cytosine
Which cells are considered pluripotent?
Stem cells because they have the potential to become any type of cell and do different roles in the body.
Name and describe one of Earth's spheres.
-Geosphere: all rock, sand, soil on Earth
-Atmosphere: all gases on Earth
-Hydrosphere: all water on Earth
-Biosphere: all living things on Earth
How do homologous structures prove common ancestry?
Similar structures require similar DNA, which comes from common ancestors.
What process causes muscles to get sore with exercise?
Anaerobic respiration/lactic acid fermentation.
What do you call the sides of the DNA?
What is the name of the process of cell replication?
Mitosis
If a primary consumers receive 950 kcal from producers, how much energy would the secondary consumers.
95 kcal
Why is variation in a species essential for evolution to occur?
There need to be differences in the genes of individuals for some to be naturally selected over others in response to environmental pressures.
Yes, for cellular respiration.
Name the pairs of nucleotides that bond to each other in DNA.
Guanine and Cytosine
Adenine and Thymine
What is cell theory?
1. All organisms are made of cells.
2. Cells come from cells.
3. Cells are the smallest functional unit of living things.
Describe a path carbon could take through all four of Earth's spheres. Include the names of the processes involved.
Answers vary.
Combustion, decomposition, cellular respiration, photosynthesis, sedimentation, fossil fuel formation, weathering, calcification, diffusion.
Teacher discretion
What are vestigial structures and how do they support the theory of evolution?
Vestigial structures: leftover/remnant structures in modern species that once had a function in the common ancestor.
What distinguishes autotroph cells from heterotroph cells?
Chloroplasts.
Which nucleotides are purines?
Adenine and Guanine
List three organelles and their functions. You may not use nucleus, mitochondria, or chloroplasts.
Answers will vary.
