Biology Exam

3. Identify the 3 domains of living things. Which domains include one-celled organisms with no nucleus?

retains the bacteria’s characteristics and an outer layer that keep characteristics of the cell that engulfed it. Mitochondria and chloroplasts are very similar in size to prokaryotes. Mitochondria and chloroplasts have their own DNA and lack histone proteins, the DNA is circular and

4. Describe the test used to detect the presence of each type of biologically important

The next organism you discover is about 1 micrometer in length, lacks a nucleus, and contains chlorophyll. Describe and defend two possible Linnaean classifications and two group classifications for this organism. (5 pts)

B. Chemoheterotroph- all protozoa, fungi, and animals and most bacteria use chemicals such as glucose for carbon and energy. Their energy and carbon is organic compounds.

B) Seasonal fluctuation of temperature is not a limiting factor in biome distribution if areas have the same annual temperature and precipitation means.

Draw a prokaryotic and a eukaryotic cell and list 3 differences between prokaryotes and eukaryotes. Be creative in drawing, but be detailed! (1.5 point)

How should the unknown microscopic organisms be classified? The concept of the experiment was to conduct a systematic observation about the traits of unknown organisms, and classify them to the right group. Making detailed observations about the traits, made it possible to identify which cell the trait belonged to because different cells have different traits. Animal cells do not have a cell wall, and has one or more small vacuoles. Plant cells has a cell wall, rectangular (fixed shape), and has a chloroplasts. Cytoplasm, Endoplasmic Reticulum, Ribosomes, Mitochondria, and Golgi apparatus to name a few.

39) Name the specific type of plant tissue or cell that performs the following functions:

4. Compare and contrast the structure of a fungal mycelium with the structure of a filamentous alga.

7. What are the different taxonomic levels (in order from the largest to the smallest taxon)?

Test taking is one of the most nerve-racking things for most people. Most of the time tests can either make or break your grade, especially if it's worth majority of your grade. That fact that one piece of paper can show how much knowledge you have attained is very scary. In my experience of test-taking, I have found out that I get nervous about tests. The first AP Biology test of the year was no exception. To prepare for the test I studied for hours on end, when the day of the test finally came I went to the review session and took the test, and then the day after I was pleased with my results.

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

Others were multicellular, and others had structures or organelles. It was hard to tell which one was which when it came to the

Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists?
