Scientific method and Basics
What is an independent variable?
What the person is changing
What is a eukaryote?
Nuclei/ membrane/ bound organelles
What are the 3 types of symmetry for an organisms? Describe what they look like.
Bilateral- 2 similar halves
Radial- around center
Asymmetircal-lack clear even divisible parts
What are the reactants of photosynthesis?
Carbon Dioxide and Water
What is the definition of an ecosystem?
A community of living organisms interacting with one another as well as non-living things
Why do we only test 1 varaible at a time?
So we can gets its information
What is a prokaryote?
No nuclei/ no memebrane/ organelles
What’s unique about mammals?
Hair/fur
4 chambered heart
What are the products of photosynthesis?
Sugar and oxygen
Charles Darwin developed the theory of evolution. Give me at least one theory
Life had a common beginning
Random varaiation of tarts among individuals in populations
Changing environment in which individuals compete Fro survival of favorable traits
What is the difference between qualitative and quantitative?
Qualitative is using words
Quantitative is using numbers
List the levels of classification from most general to most specific:
-Kingdom
- Phylum- Class
- Order
- Family
- Genus
- Species
What does “amphibious” mean?
Both kinds of life
What are the two types of vascular tissue, and what do they carry?
Xylem- water and nutrients
Pholem- glucose
What is the difference between microevolution and macroevolution?
Micro- Small change to a single population(drug resistance and beak shape)
Macro- Big changes between species( common ancestors like birds and dinosaurs)
What is the difference between a control group and an experimental group?
Control- compares
Experimental- get the IV
What is an autotroph and what is another name for an autotroph?
- Make their own food
- Producers
Which organisms have “soft” bodies that must be protected by shells? Give me a least three
Snails, clams, and mollusca
What are the major organs of vascular plants, and what do they do?
Roots- organs that anchor the plants to the groun d and absorb water from the sloil
Stems- carry Tu stances back and forth between the roots and leaves
Leaves- organs that carry photosynthesis
Charles Darwin developed a theory of evolution and came up with ideas. What was at least one of his ideas?
- Life had a common beginning; new forms of life branch off from earlier forms
- There is a random variation of traits among individuals in populations
- A constantly changing environment in which individuals compete for survival results in selection of favorable traits
- Each adaptation is small but cumulative selection over time results in increasing different life forms and eventually new species
Give me an if then because hypothesis on why cleats are very good for soccer?
Your answer
What is a dichotomous key and how can it be helpful
- classification key
- helping identify the identity of the item
Compare and contrast echinoderms and sponges. Give me at least four points for each.
Echinoderms- radial, no external skeleton, but have a thin outer skin that covers an internal skeleton made of tiny plates and spines that provide RIGID SUPPORT, unique water vascular system, open circulatory system
Sponges- have pores, they cannot move, specialized cells, must filter water to separate out the organisms they want to eat from those they do not
Label the parts of the flower.
Stamen-anther-filament
Petal
Ovule
Sepals
Pistil-stigma-style-ovary
List the 5 causes of microevolution
1. Small population
2. Non-random mating
3. Mutations
4. Gene flow
5. Natural selection
