Basically, cells are the basic units of life and living organisms are made up of one or more cells
Some prokaryotic cells are "anaerobic" referring to their:
They don't need oxygen to live
Small cells tend to have:
Increased membrane surface area
The process of making proteins is:
transcription & translation -- engineer & factory -- copy plans & send them off to be assemble
Specialized, membrane bound structures within cells are known as:
The endoplasmic reticulum is:
the “cell highway” that performs transportation duties within a cell
Every cell has the following three components:
Cell Membrane, cytoplasm, genetic material
One of the functions of a vacuole in a plant cell is to:
store, support, and regulate water
The universal form of energy in all living cells is:
Moving hydrogen ions from one side of a membrane to the other:
The lifespan of a lipid bilayer in the membranes is generally:
measured in hours
The “Endosymbiosis Hypothesis” proposes that:
Mutualistic relationship between different organisms and capable of independent reproduction
The overall function of mitochondria is to:
“Cell power plant” Used to generate most of the cells store of ATP -- also Break down fats and sugar to ATP.
Which of the following are examples of kinetic energy?:
Wind, flowing stream, electricity, heat
The First Law of Thermodynamics tells us that:
whatever energy you put into a system is energy you will get out
As “energy organelles” plant cells have:
The first orgasms on Earth occurred about:
3.8 billion years ago
Autotrophic organisms get their energy from:
The early atmosphere of the Earth had:
Hydrogen, ammonia, methane, water vapors, but NO oxygen
“Family” is a level in the Linnaean classification hierarchy between:
Order and Genus
When tectonic plates tipped, they influenced evolution by:
Changing the environment with the movement of continents, coastlines varied, sea levels changed
The multicellular kingdoms differ in their:
cells (prokaryotic/eukaryotic) - how they eat - plants: photosynthesis, fungi: absorbtion, animals: ingestion Modes of Nutrition
Scientific names are used instead of common names because:
Universal and more efficient
Linnaeus named a plant “Siegesbeckia” in order to:
Spite the guy that the plant is named after
In which Kingdom do we classify viruses?
Viruses are composed of:
capsid & genetic material.
are viruses that attack bacteria.
HIV infection attacks the:
T4 lymphocytes (immune system cells); basically attacks the whole immune system
Which of the following is true of viruses outside the host cell?
viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert --- someone double check this!
Which of the following human diseases is not caused by viruses?
HIV stands for:
Human Immunodeficiency Virus
The Spanish Flu:
influenza pandemic that spread widely across the world.-- also known as H1N1. 20-50 million deaths worldwide.
A problem associated with the development of a vaccine against the Bird Flu virus:
The virus is constantly mutating, vaccines are developed from chickens, eggs, and embryos and the virus is killing them all
In the movie, what epidemic did Dr. John Snow prevent in 1854 in London?
The Bird Flu is caused by what strain of virus?
Why were young children the first casualties of the Bird Flu in Thailand?
The task of plucking the feathers off chickens is usually the job of children.
Where did the Bird Flu come from?
What percentage of the people who catch the Bird Flu die from it?
Which of the following might be effective in preventing the Bird Flu from becoming a pandemic?
Global surveillance, response teams, developing a vaccine.
New DNA data will probably be most important in showing evolutionary relationships in kingdom:
The two kingdoms that are most different are:
Monera vs. Protista
Azolla and its associated cyanobacterium are:
Symbiotic and helpful to the growth of other plants
An example of why the two kingdom system of classification was not workable is:
Didn’t describe the MANY differences and variations of species efficiently
The reason the Kingdom Protista is difficult to characterize is:
Has a very wide and complex variety of species
Members of Phylum Sarcomastigophora feed by:
Pseudopods and cilia
Characteristics of Phylum Myxomycota include:
Fungus-like i have a feeling this will be one of those “Which of the following is NOT one of …”
Diatoms often look like:
The evolutionary process of “cephalization” is the development of:
being able to eat and excrete at the same time
The stiffness of a sponge is due in part to:
Spicules in endoskeleton
Organ systems are found in all animal phyla except:
Oxygen and carbon dioxide are distributed in flatworms by:
Diffusion through body
Which of the following phylum are characterized by having stinging cells?
Which of the following is radially symmetrical?
Cnideria and adult Echinodermata
The animal phylum with the most species is:
Anthropoda -- Correct. They have 10 million species yay! :D lol
A key evolutionary development in phylum Nematoda was:
Having a separate anus and mouth
Cell wall of fungi is composed of:
The mode of nutrition in fungi is:
The reason why one fungal Phylum is called Imperfect Fungi is because:
Sexual reproduction unknown
An infection by mycorrhizae:
is a fungus root
Modern terrestrial plants probably evolved from which algae?
Chlorophyta (green algae)
Sexual reproduction in ferns and bryophytes requires ____.
The most successful plant Phylum based on the number of species is:
Flowering plants aka Diverse Anthophyta
Fruits are produced by flowering plants to promote:
pollination Also dispersion right? (animals)
According to the movie, the human population originated in _____.
______ Was/were used to determine the lineage of the human race.
Blood and DNA
The first humans to leave Africa migrated to:
Why did the early humans migrate from their original homeland?
Which of the following are not "closely" related to the others?
How long ago did humans first leave their place of origin?
50,000 years ago
How did humans migrate from Siberia to North America?
