Biology Test

Why do scientist use taxonomy to classify organisms? to organize organisms based on similarities.
Why do scientist need to assign scientific names to organisms? because of different virus in different languages and regions of the animal
Based on their scientific names, do Canis Latrans and Canis familiaris belong to the same genius? Yes
Based on their scientific names, do Canis Latrans and Canis familiaris belong to the same genius? No
List the 7 levels of classification in order starting with the broadest group and ending with the most specific group. Kingdom, Phylum, Class, order, family, Genius, Species
Which two levels of classification are used to name an organism? Genius Species
Which one of the two level of classification is capitalized? Genius
This type of level of classification naming is called Binomial Nomericlatures
Which two organisms listed in the above chart are most closely related to each other? Blue whale/ coyote
Which level of taxonomy shown in the chart indicates whether an organism is a mammal or not? Class
What are the key features that distinguish each group from the others for Kingdom Archaebacteria: Prokaryote, extremophiles, unicellular
What are the key features that distinguish each group from the others for Kingdom Eubacteria Prokaryote, unicellular, decomposers
What are the key features that distinguish each group from the others for Kingdom Protista Unicellular, multicellular, some move
What are the key features that distinguish each group from the others for Kingdom Fungi multicellular, no movement, cell wall=chitri
What are the key features that distinguish each group from the others for Kingdom Plantae autotroph, multicellular, cell well=cellulose
What are the key features that distinguish each group from the others for Kingdom Animalia heterotroph, multicellular, movement
The outer protein coat of a virus is called a Capsid
Where are the instructions for making new copies of virus found? DNA or RNA
List all of the viral diseases we have discussed HIV, Hepatitis A, B, C, Chicken Pox, Flu, Cold
Can viral diseases be treated with antibiotics? No
What can be used to prevent them? Vaccines
Viruses causes disease by doing what to the body? Destroying cells
What is the name of the virus that causes AIDS HIV
What does AIDs do to the immune system? Weakens it
Which type of cells does it attach? Helper T- cells
How do viruses "reproduce"? Make copies
What happen to the host organism after the reproduce? get sick, cells get destroyed
List the first step of the lytic cycle? Viruses attaches to the cell
List the second step of the lytic cycle? DNA/RNA injected into the cell
List the third step of the lytic cycle? DNA/RNA is copied
List the fourth step of the Lytic cycle? Viruses copies itself
What is the fifth step of Lytic cycle? Cell bursts and releases new viruses
Describe the lysogenic cycle incorporated into cell DNA, gets replicated and the virus attaches to the cell inserts DNA/RNA, DNA/RNA with cell DNA, no diseases shows up. Lays Clormani for a period of time or until stressed.
What do viruses and living cells have in common? Genetic material; ability to evolve
Viruses are smaller that bacteria True/False True
Viruses metabolize food for energy False
Viruses can reproduce on their own False
What type of organism is this? Bacteria

List the kingdoms of bacteria called Archaebacteria Unicellular, ancient, extremophiles
List the kingdoms of bacteria called Eubacteria Unicellular, prokaryotic, aerobic/anaerobic conditions
Why are archaebacteria able to survive in harsh environment Evolved to survive - enzymes changed
How do bacteria help maintain equilibrium decomposers
There are bacteria in the body that are beneficial to humans? True/False True
Where in the body are these bacteria found? intestines, stomach
In what food can beneficial bacteria be found? Yogurt, cheese, milk
What are the factors that help spread disease causing bacteria Having access to a new host
Last the bacteria infections we have discussed? Pneumonia, Strep, TB, tooth decay, Bacteria meningitis
What are some of the symptoms of bacteria infections? bad breath, Syphilis, anthrax, staph
