all science stuff we need to know for EOC
| Question | Answer |
|---|---|
| The process by which an organism's internal enviornment is kept stable in spite of changes in the external enviornment | homeostasis |
| What structure directs the activites of a cell? | nucleus |
| Messages are carried back and fourth between the brain and other parts of the body by | nervous tissue |
| Which organ system makes blood cells? | skeletal system |
| Which type of human body tissue can contract or shorten? | muscle tissue |
| What is NOT a function of hte skeleton? | obtaining oxygen |
| The spaces in bones are filled with a soft connective tissue called | marrow |
| Which type of muscle is found only in the heart? | cardiac muscle |
| Which type of muscle tires quickly during excercise? | skeletal muscle |
| How do pairs of skeletal muscles work together? | While one muscle in the pair contracts, the other returns to its original length. |
| How does the skin protect the body from disease? | by keeping disease causing microorganisms from entering the body. |
| How does the skin help regulate body temperature? | by enabling excess heat to escape from the body. |
| Beneath the outer membrane of bone there is a layer of | compact bone |
| Which is NOT a function of the cardiovascular system? | controlling many body processes by means of chemicals |
| blood vessels that carry blood away from the heart are called | arteries |
| In which vessels are materials exchanged between the blood and body cells? | capillaries |
| Which component of blood carries oxygen to the body cells? | red blood cells |
| If a person's blood lacked platelets, what process couldn't take place? | clotting of blood |
| Which component of blood is 90% water? | plasma |
| The function of white blood cells is to | fight diseases |
| What structure enable the small intestine to absorb large ammounts of nutrients? | villi |
| Which process takes place in the large intestine? | Water is absorbed from undigested food. |
| what substance in the mouth contains an enzyme that begins chemical digestion? | saliva |
| what process involves muscle contractions that move food through the esophagus? | peristalsis |
| What substance coats and protects the inside of the stomach? | mucus |
| IN what part of hte body does most chemical digestion take place? | small intestine |
| What organ produces bile? | liver |
| What digestive organ releases enzymes that help break down starches, proteins, and fats in the small intestine? | pancreas |
| Vascular plants are differ than nonvascular plants in | how they transport materials |
| What is not a characteristic of a plants vascular tissue? | it transports egg and sperm cells for reproduction |
| What happens in the phloem? | Food moves down from leaves |
| Plants that produce seeds | can live in relatively dry enviornments. |
| What characteristic do gymnosperms share? | They produce seeds that are not enclosed by fruits. |
| The reproductive structures of most gymnosperms are called? | cones. |
| All angiosperms | produce fruits. |
| How are angiosperms different from gymnosperms? | Angiosperms produce fruit. |
| Gases pass in and out of a leaf through the | stomata |
| What is not a root function in plants? | to produce food. |
| Which substances are produced during respiration? | carbon dioxide and water |
| Where in the respiratory system does gas exchange occur? | in the alveoli. |
| The role of the respiratory system is to bring what substance into the body? | oxygen |
| The dome-shaped muscle that plays an important role in breathing is the | diaphragm. |
| What is the main function of the excretory system? | to collect and remove wastes from the body. |
| Which excretory organ eliminates water and some chemical wastes in perspiration? | skin. |
| what term do scientists use to describe the chemical process in which oxygen and glucose react to realease energy inside body cells? | respiration |
| Each alveolus is surrounded by a network of | capillaries |
| When the nervous system makes you feel hungry or thirsty, what body process is it helping to carry out? | maintaining homeostasis. |
| a change or signal in the enviornment that can make an organism react is called an | stimulus. |
| What part of the brain controls memory? | cerebrum |
| A synapse is the space between | an axon and hte structure that recieves the nerve impulse |
| The three regions that make up the brain include the cerebrum, cerebellum, and | brain stem |
| What are the products of photosynthesis? | oxygen and sugars |
| What happens during photosynthesis? | The cell uses the energy in sunlight to make food. |
| How does photosynthesis benefit heterotrophs? | It creates food that they can eat. |
| What happens during respiration? | Glucose is broken down, releasing energy. |
| How are photosythesis and respiration related? | The have opposite equations |
| Together, respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere | constantly changing |
| Consumers that eat both plants and animals are called? | omnivores |
| Which is a consumer that is a herbivore? | deer |
| A diagram that shows the amount of energy that moves from one feeding level to another in a food web is called? | energy pyramid |
| IN an energy pyramid, which level has the most available energy? | producer level |
| In which process do producers use carbon from carbon dioxide to produce other carbon-containing molecules? | photosynthesis |
| An organism that can make its own food is called? | producer |
| The first organism in a food chain is always | producer |
| What do producers release as a result of photosynthesis? | oxygen |
| The number of organisms an area can support is called? | carrying capacity |
| What is NOT a limiting factor? | soil |
