A way of learning about the natural world!
What is "science"
100
What is the name of the scientist who boiled broth to prove that living things (in this case, bacteria) could only be produced by other living things (no spontaneous generation!)?
What is "Louis Pasteur"
100
The stage of mitosis in which the chromatin condenses into chromosomes and the nuclear envelope begins to disappear is called ________.
What is "prophase"
100
The community of organisms that live in a particular area, along with their nonliving surroundings = ?
What is "ecosystem"
100
The area between the highest high-tide line and the lowest low-tide line is called the _________.
What is "intertidal zone"
200
This scientific skill involves making a forecast of what will happen in the future based on past experience or evidence.
What is "predicting"
200
What did Anton van Leeuwenhoek do?
What is "He was a Dutch cloth salesman who made his own simple microscopes. He looked at drops of pond water under his microscope, and was the first to observe living, moving cells"
200
When 2 or more elements combine chemically, the form a _________.
What is "compound"
200
This type of interaction between organisms is when one organism kills another for food.
What is "predation"
200
Trees that produce their seeds in cones and have leaves shaped liked needles are called _________.
What is "coniferous trees"
300
Name 4 examples of careers in life science
What is "botanist, marine biologist, park ranger, health-care"
300
Name 3 of the 5 characteristics of living things.
What is "1.) made of cells, 2.) made of similar chemicals (water, carbohydrates, proteins, nucleic acids, lipids), 3.) respond to their surroundings, 4.) grow and develop, 5.) reproduce"
300
Which elements are proteins made of? Name one function of a protein (must answer completely to get points)
What is "CHON(S) - carbon, hydrogen, oxygen, nitrogen, sulfur. Enzymes, or molecules that speed up reactions in the cell, are proteins. Proteins also make up cell organelles, and can be found in the cell membrane"
300
Is soil a biotic or an abiotic factor? Why?
What is "soil is both abiotic and biotic - it contains components that are nonliving (such as sand, pieces of rock), but also components that are living (bacteria, fungi)"
300
Name 3 characteristics of the deciduous forest biome.
What is "1.) trees shed their leaves and grow new ones every year, 2.) enough rain to support tree and plant growth (at least 50cm/yr), 3.) temperatures vary greatly throughout the year (hot summers, cold winters), 4.) different species include oak & maple trees, chipmunks, black bears, deer, etc"
400
A scientist wants to test the effect of temperature on mold growth. Name 3 factors that s/he needs to control in order to tease out this relationship?
What is "examples: light, water, type substrate (i.e. food for the mold - bread? apple? pasta?"
400
Name 2 of the cell organelles that are involved in protein synthesis. What exactly do these organelles do?
What is "nucleus: DNA codes for how to make the protein; ribosomes: manufacture the proteins; rough endoplasmic reticulum: modifies the proteins; golgi apparatus: packages and transports the proteins"
400
In the process of diffusion, molecules move from an area of _____ concentration to an area of ________ concentration.
What is "high, low"
400
Name 4 predator adaptations that enable predators to hunt and kill their prey more effectively.
What is "e.g. speed, sharp teeth & claws, camouflage coats, poisons, large eyes for spotting prey, etc"
400
Describe how humans are impacting both the carbon cycle and the nitrogen. Provide 2 ways for each cycle.
What is "carbon cycle: burning fossil fuels, clearing forests; nitrogen: fertilizer runoff, burning fossil fuels releases nitrogen-containing compounds into the atmosphere"
500
What do the 3 safety symbols that Emily d. has projected mean?
What is "1.) Corrosive, 2.) slipping hazard, 3.) heat-resistant gloves"
500
How does the structure of the plant cell reflect the overall needs of a plant? Provide examples.
What is "chloroplasts: where photosynthesis takes place, sugars and oxygen are produced; cell wall: provides rigidity, helps support overall plant structure; vacuole stores lots of water - water is needed for photosynthesis, also provides added support to cell overall"
500
What are the names of the nitrogenous bases that make up the steps of the DNA "ladder"? How do they pair up with each other? (must answer completely correctly to score points)
What is "adenine pairs with thymine, guanine pairs with cytosine"
500
Provide examples of the 3 different types of symbiosis among the Anacapa community.
What is "1.) mutualism: both benefit, 2.) commensalism: 1 benefits, 1 is not harmed, 3.) parasitism: 1 organism lives on or inside another organisms and harms it"
500
Pick 2 biomes, one with high rainfall and one with low rainfall. First, how much rainfall per year do they each get? Second, name 2 adaptations of organisms that live in this biome that reflect how much rainfall the biome receives.
What is "e.g. desert: low rainfall (<25cm/yr), not much vegetation, plants are especially adapted to dry conditions (succulents) and animals are most active at night when it's cooler; rainforest: >300cm/yr, lots of vegetation so there are understory plants that grow well in the shade, and tall trees that can reach the light above the other plants"
