What type of generations do plants alternate between during a life cycle? | All plants have a life cycle that alternates between haploid and diploid generations. Plants vary in terms of which generation is dominant. Most modern plants have a dominant diploid generation. | https://huggingface.co/datasets/allenai/sciq |
Genetic diversity in a population comes from two main sources - sexual reproduction and what else? | Variation and Adaptation Natural selection can only take place if there is variation, or differences, among individuals in a population. Importantly, these differences must have some genetic basis; otherwise, selection will not lead to change in the next generation. This is critical because variation among individuals ... | https://huggingface.co/datasets/allenai/sciq |
What state of matter completes the list: solid, liquid, gas? | A snowflake is made of ice, or water in the solid state. A solid is one of four well-known states of matter. The other three states are liquid, gas, and plasma. Compared with these other states of matter, solids have particles that are much more tightly packed together. The particles are held rigidly in place by all th... | https://huggingface.co/datasets/allenai/sciq |
The heart, blood vessels, and blood make up which system in the body? | The cardiovascular system is made up of the heart, the blood vessels, and the blood. | https://huggingface.co/datasets/allenai/sciq |
Which elements fall between metals and nonmetals in the periodic table? | Metalloids are elements that fall between metals and nonmetals in the periodic table. Just seven elements are metalloids, so they are the smallest class of elements. In Figure above , they are color-coded orange. Examples of metalloids include boron (B), silicon (Si), and germanium (Ge). | https://huggingface.co/datasets/allenai/sciq |
What kind of reactions are involved in processes ranging from the contraction of muscles to the digestion of food? | The rates at which chemical reactions take place in organisms are very important. Chemical reactions in organisms are involved in processes ranging from the contraction of muscles to the digestion of food. For example, when you wave goodbye, it requires repeated contractions of muscles in your arm over a period of a co... | https://huggingface.co/datasets/allenai/sciq |
Mycorrhizae functions as a physical barrier to what? | Mycorrhizae: The Symbiotic Relationship between Fungi and Roots A nutrient depletion zone can develop when there is rapid soil solution uptake, low nutrient concentration, low diffusion rate, or low soil moisture. These conditions are very common; therefore, most plants rely on fungi to facilitate the uptake of mineral... | https://huggingface.co/datasets/allenai/sciq |
What do skeletal muscles enable the body to do? | Skeletal Muscles. Skeletal muscles enable the body to move. | https://huggingface.co/datasets/allenai/sciq |
What is the sum total of all body reactions? | Water is an essential part of most metabolic processes within organisms. Metabolism is the sum total of all body reactions, including those that build up molecules ( anabolic reactions ) and those that break down molecules ( catabolic reactions ). In anabolic reactions, water is generally removed from small molecules i... | https://huggingface.co/datasets/allenai/sciq |
What type of reproduction involves combining genetic material from two parents to create distinct offspring? | That is the main difference between sexual and asexual reproduction. Sexual reproduction is combining genetic material from two parents, usually from two gametes. How the two cells combine may take many forms, but does not necessarily involve physical contact. Sexual reproduction produces offspring that are genetically... | https://huggingface.co/datasets/allenai/sciq |
