S. Midterm Review
This is a study guide for my science midterm :)
| Question | Answer |
|---|---|
| Decide whether characteristics of living things are something robots do or robots do not do. Which things can robots and living things do? | Respond to their environment and Use energy. |
| The best way for farmers to prevent fungi from growing is to make sure there is not enough ________ for fungi to survive. | Water |
| What is the difference between a unicellular organism and a multicellular organism? | .Unicellular organisms perform all functions for life with one cell. Multicellular organisms have many cells that work together to keep them alive. |
| Lizette deduces that the weeds must be reproducing because there is no such thing as ____. | Spontaneous generation. |
| What must also be present for the vegetables to grow and thrive? | Food |
| What variables should Lizette keep the same between the control group of weeds and the sprayed weeds? | Lizette should keep the same amount of solution or water, same amount of sunlight, and same kind of plant. |
| How did all these animals end up using similar poisons? | All the animals evolved similar characteristics by convergent evolution. |
| Order the species based on their relationship to the black bear from closet-related animal to the most distantly-related. | 1. Polar bear 2. Giant Panda 3. Gray Wolf 4. Zebra |
| Which domain do anteaters belong to? | Eukarya |
| Look at the table showing the Linnaean levels of classification for the giant anteater. Then create the scientific name for the species. ( Genus goes first than species ) | Myrmecophaga tridactyla |
| What are the levels of classification aardvarks have in common with anteaters? | A. Domain B. Kingdom C. Phylum D. Class |
| How do taxonomists decide classification of organisms in the Linnaean system? | Taxonomists decide classification of organisms by separating them by characteristics and ancestors. |
| Even though termites are animals and Trichonymphs are protists, what do both organisms have in common? | Both are Eukaryotic. |
| Which one of these groups is a non-living agent of disease? | Viruses |
| Mushrooms are _____ that use spores for ______. | fungi, reproduction |
| How do bacteria survive for so long during harsh conditions until finding a host? | They form an endospore with thick walls and await better conditions. |
| Explain why it isn't accurate to call a virus that kills bacteria a "bacteria eater". What happens when a virus attacks a cell? | It is not accurate to call a virus that kills bacteria a "bacteria eater" because it doesn't eat bacteria or anything else. It gets its genetic material to the host cell, forces it to make copies, than destroys the cell and moves on. |
| Which cell parts contribute to plant cell functions and are not found in animal cells? | Large vacuole, chloroplasts, and a cell wall. |
| Characteristics that animals inherit to survive in their environment are called _____. Along with water conservation, animals also have uniques characteristics for _____. | adaptations, movement |
| How would she describe the characteristics of the organisms? | Eukaryotes, made of one or more cells, nucleus that holds DNA. |
| Vascular Plants have | xylem and phloem, true roots, and a cuticle |
| Nonvascular Plants have | no roots and thin cell walls |
| What kind of organization describes and animal's body structure? | cells, tissues, organs, organ systems |
| Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms? | Their body structure becomes increasingly more complex. |
| Identify and explain the traits that vertebrate have in common. | Vertebrates have a notochord, nerve chord, and pouches in their throat . Ectotherms are the way they maintain homeostasis and most have a back bone to protect their nerve chord. |
| Which other kinds of organisms are composed of cells? | All organisms are composed of cells. |
| Which functions must all cells perform to survive? | Bringing in nutrients and water, getting rid of wastes, and obtaining energy. |
| Even without knowing anything else about the cells he sees, what can Terry reasonably conclude about them? | The cells were produced by other cells. |
| What is wrong with Terry's suggestion? | Cells are the basic unit of life, and they do not have more cells inside of them. |
| Predict how James will improve the view of the sample. How will the magnification and resolution of the image change? | James will improve the view of the sample by changing the objective lens to 40x and will make the magnification and resolution increase, giving more detail to the image. |
| If all these cells are mouse cells, why do they look so different from each other? | Different cells specialize in different functions. |
| A group of similar _____ make up a tissue. Several tissue make up an _____. | cells, organ |
| Which organelle is affected by Lauren's disease? (cystic fibrosis) | cell membrane |
| Which organelle is affected by mosaic viruses? | chloroplast |
| Which organelle is affected by Joe's disease? | mitochondrium |
| How do these structures help plant cells to meet a plant's needs? | Plants have a cell wall and chloroplasts. The cell wall protects and supports the cell while chloroplasts take energy and convert it into food for the cell. |
