Living organisms are placed into how many kingdoms of organisms?
|
Five
|
|
|
Monera
|
Prokaryotic ( cells without a nucleus bounded by a membrane. (i.e. bacteria)
|
|
|
Protista
|
Eukaryotic ( cells with a nucleus bounded by a membrane ) (i.e. amoebae,flagellates,algae)
|
|
|
Fungi
|
Eukaryotic ( usually with a simple mlticellular body in the form of a mass of slender filaments ) (i.e. mushrooms, molds)
|
|
|
Animalia
|
Eukaryotic (multicellular, body usually complex and with many types of true tissues) (i.e. All types of animals, such as sponges, worms, vertebrates)
|
|
|
Plantae
|
Eukaryotic (multicellular,same as animalia body..but rarely parasitic and cells always surrounded by a cell wall made of cellulose (i.e. flowering plants, conifers, ferns, mosses)
|
|
|
To be alive?
|
Always made of cells, they respond to stimuli, they reproduce, they exhibit growth and development, they obtain food and metabolize it for the generation of energy and the synthesis of materials for growth and life, they possess nucleic acid(s), and they exhibit some adaptation to environmental conditions.
|
|
|
Organisms are composed of matter: T or F
|
True
|
|
|
All matter whether organic or inorganic, obeys certain physical and chemical laws.
T or F |
True ( These laws form the foundation for the life sciences, Biology,Chemistry,Physics, Anatomy and Physicology)
|
|
|
The cell is the basic structural and functional unit of an organism.
|
All cells have cytoplasm and a cell membrane.
1. Prokaryotic- lack a nuclear membrane surrounding the DNA. 2. Eukaryotic cells possess a nuclear membrane that surrounds the DNA and separates it from the cytoplasm, creating a well-defined nucleus. |
|
|
What is an example of Eukaryotic Cells?
|
Red blood cells of humans. They lack a nucleus at maturity for functional reasons, however these cells always possess a nucleus during their development.
|
|
|
Typical plant cells lack a centriole, but have plastids and a cell wall.
|
On the flip side, typical animal cells lack a cell wall and plastids, but possess a centriole.
|
|
|
What does reproduction of cells usually involve?
|
Mitosis (a nuclear process during which nuclear materials, including DNA, are distributed equally to daughter nuclei.
|
|
|
DNA replicates itself during interphase, before the nucleus enters the mitotic process.
T or F |
True (also Mitosis may occur without division of the cell, leading to a multinucleate cell. )
|
|
|
Organelles?
|
Parts of a cell.
|
|
|
The Cell Membrane is kinda like the bodyguard for the cell, letting some pass and some not.
|
True, but materials may still pass through Osmosis, diffusion, active transport or by some other mechanism.
|
|
|
Cellular organelles in which food is oxidized for the release of energy.
|
Defined as Mitochondria
|
|
|
Examples of Plastids ( in plants)
|
Chloroplasts are green plastids in which photosynthesis occurs.
2. Chromoplasts and leucoplasts function in storage and other processes. |
|
|
Endoplasmic reticulum
|
basically a network or a passage for materials inside the cytoplasm of the cell.
|
|
|
Ribosomes
|
organelles in which protein synthesis occurs. ( RNA passes over the ribosomes to line up the amino acids to form the protein. )
|
|
|
Golgi apparatus
|
how the cell releases secretions.
|
|
|
Absolute Zero
|
The lowest temperature a gas can attain. This is 460 degrees below zero on the Fahrenheit scale and 273 degrees below zero on teh celcius scale.
|
|
|
Absorption
|
The movement of water and/or dissolved substances into a cell, tissue, or organism.
|
|
|
Acceleration
|
A change in speed of an object. Up is called pos accel and Down is called neg accel.
|
|
|
Acid
|
A compound with a pH less than 7, which means that it releases hydrogen ions when dissolved in water. An acid changes blue litmus paper to "red" and tastes sour.
|
|
|
Acquired Immunity
|
Immunity that is not natural or congenital, obtained after birth.
|
|
|
Active Immunity
|
Immunity brought about by activity of certain cells of the body as a result of being exposed to an antigen.
|
|
|
Active Transport
|
An energy-requiring process by means of which materials are moved across a cell membrane.
|
|
|
Adsorption
|
The gathering of molecules of a substance on a surface.
|
|
|
Aerobe
|
Any organism living in the presence of and utilizing free, molecular oxygen (that is, oxygen not in chemical combination) in its oxidative processes.
|
|
|
Alchemy
|
The science of transforming less valuable metals into gold or silver, and the philosophy behind this idea. The theories of the alchemists of the middle ages were false, but their experiments laid the foundation for modern chemistry.
|
|
|
Alkali
|
A compound with a pH greater than 7. An alkaline substance changes red litmus paper to blue, and it can combine with hydrogen.
|
|
|
Alkaline
|
A substance having the properties of an Alkali.
|
|
|

a. H2O b. H2O2 c. HgO d. PbO2 |
H2O
|
|
|
All of the reactions between the following pairs will produce hydrogen EXCEPT
a. copper and hydrochloric acid b. iron and sulfuric acid c. magnesium and steam d. sodium and alcohol |
Copper and Hydrochloric acid.
|
|
|
When hydrochloric acid is added to sodium sulfite, and the gas that is formed is bubbled through barium hydroxide, the salt formed is
a. BaC1(2) b. BaSO(3) c. NaC1 d. NaOH |
BaSO(3)
|
|
|
If 3,480 calories of heat are required to raise the temp of 300 grams of a substance from 50C to 70C, the substance would be:
|
Use the formula:
c=Q/MDT c=specific heat Q=number of calories M=mass T=temperature answer is ethyl alcohol ( specific heat - 0.581 ) |
