Biology |
Study of life |
|
5 characteristics of all living things |
Energy, reproduction, organization, cells, homeostasis, growth/development, evolve |
|
Organization of life from smallest to largest{12} |
Atom>molecule>organelle>cell>tissue>organ>organ system>organism >population>community>ecosystem>biosphere |
|
How do humans receive their energy? |
Through consumption,we are consumers |
|
How do producers get their energy? Give an example |
They extract their energy and nutrients from the enviornment. Ex. Plants and some bacteria |
|
How do decomposers obtain energy? Give and example. |
Obtain nutrients from dead organisms and organic wastes. Ex. Fungi and some bacteria |
|
Name the 7 classification systems |
Kingdom, phylum, class, order, family, genus, species |
|
Organisms that do not move and are rooted to one spot are considered what? |
Sessile |
|
Evolution |
Change in a species over time |
|
Which type of reproduction contains gametes? |
Sexual reproduction |
|
Name four types of eukaryotes |
Animals, protista, plants, fungi |
|
Name two types of prokaryotes |
Bacteria and archaea. |
|
Matter |
Is anything that takes up space (solid,gas,liquid) |
|
What does "CHNOPS" stand for? |
Carbon. Nitrogen. Phosphorous Hydrogen. Oxygen. Sulfur |
|
Why do elements either chums hare of steal from other elements? |
To become stable |
|
Name some aspects of inorganic compounds. Give two examples |
They are nonliving, nonbiodegradable, do not contain carbon. Ex. H2o, acids, bases, salts. |
|
Name concepts or organic compounds and three examples |
Biodegradable, contain carbon or hydrogen, and living. Ex. Carbs, lipids, proteins, nucleic acids. |
|
What's stronger: covalent or ionic bonds? |
Covalent, since they are sharing. |
|
Which bond breaks easier in water? |
Ionic bonds |
|
What does ph measure? |
The amount of acids and bases. |
|
How do buffers maintain their constant ph? |
By releasing or consuming hydrogen. |
|
Asexual reproduction |
Usually don't by sponges or fungi, asexual reproduction leads to the offspring almost looking identical and they only come from one parent. |
|
Sexual reproduction |
Comes from two parents and avoids children looking identical, they are very diverse. Exeternal anf internal fertilization Ex. Plants, animal, humans |
|
Name two heterotrophs |
Decomposes and consumers. |
|
Name the three domains |
Eukarya, bacteria and archaea |
|
Taxonomy |
Study of naming and classifying organisms |
|
Element |
Substance that cannot be broken down through chemical means. |
|
True or false: Animals contain two sets of genetic material. |
True, they are diploid |
|
What are hydrogen bonds? Are they strong or weak? |
It is the superglue of bonds containing hydrogen. They are weak and happen through adjacent water molecules. |
|
Solvent |
A chemical in which solutes dissolve |
|
Solution |
Consists of one or more solutes dissolved in a liquid solvent. |
|
"Like dissolves like" |
Polar molecules can dissolve polar molecules. Same with nonpolar. |
|
Hydrophilic Give example |
Polar Water loving. Substances dissolve in water ex. Sugar,salt, ions |
|
Hydrophobic Give examples. |
Nonpolar Water fearing. Substances do not dissolve in water. Ex. Fats and oils |
|
Zygote |
A fertilized egg |
|
How do we behave towards achieving homeostasis? |
We can behave physiologically or behaviorally towards hypo- or hyper- thermia. |
|
Extant |
Adaptation towards enviornment over time. Antibiotic resistance |
|
Are archaea unicellular or multicellular |
Unicellular |
|
Independent variables |
Altered in an experiment. |
|
Dependent variable |
A response that can depend in the value of the independent variable. The MEASURED part of an experiment. |
|
Standardized variable |
The constant part of an experiment, including the control group. |
|
Theory |
An explanation for natural phenomenon |
|
Scientific method |
Begins with questions and observations. Then hypothesis>prediction >experiment>analysis> peer review |
|
Characteristics of water. Name 6 |
Cohesion, adhesion, chemical reactions, regulate climate And temperature, expands when it freezes,participated photosynthesis and respiration. |
|
Denature |
Ph and temperature affect proteins and their functions. (Ruins them) |
|
Enzymes and in what suffix |
-ase |
|
Monosaccharides |
Quick energy. Ex. Glucose and fructose |
|
Dissacharides |
Used for energy. Ex. Sucrose and lactose |
|
Polysaccharides examples |
Glycogen, starch, cellulose, chitin>exoskeleton |
|
Glycogen |
How animals store energy ex. In Liver, muscle |
|
Name 7 types of proteins |
Structural/support/storage proteins, hormones, receptor, enzymes, transport, defensive, contractile |
