Answer the following question given this paragraph: Observational learning is learning by watching and copying the behavior of someone else. Human children learn many behaviors this way. When you were a young child, you may have learned how to tie your shoes by watching your dad tie his shoes. More recently, you may have learned how to dance by watching a pop star dancing on TV. Most likely, you have learned how to do math problems by watching your teachers do problems on the board at school. Can you think of other behaviors you have learned by watching and copying other people?. Q: What is the term for learning by watching and copying the behavior of someone else? Choices: - consequential learning - associative learning - classical conditioning - observational learning A:
(Answer)
observational learning
Ques: Answer the following question given this paragraph: larger cities and economic growth therein leads to the construction of dams, the consequent flooding of ecosystems, and increased emissions of pollutants. Other threats to tropical forests come from poachers, who log trees for their precious wood. Ebony and Brazilian rosewood, both on the endangered list, are examples of tree species driven almost to extinction by indiscriminate logging. The number of plant species becoming extinct is increasing at an alarming rate. Because ecosystems are in a delicate balance, and seed plants maintain close symbiotic relationships with animalswhether predators or pollinatorsthe disappearance of a single plant can lead to the extinction of connected animal species. A real and pressing issue is that many plant species have not yet been catalogued, and so their place in the ecosystem is unknown. These unknown species are threatened by logging, habitat destruction, and loss of pollinators. They may become extinct before we have the chance to begin to understand the possible impacts from their disappearance. Efforts to preserve biodiversity take several lines of action, from preserving heirloom seeds to barcoding species. Heirloom seeds come from plants that were traditionally grown in human populations, as opposed to the seeds used for large-scale agricultural production. Barcoding is a technique in which one or more short gene sequences, taken from a well-characterized portion of the genome, are used to identify a species through DNA analysis. Q: What type of seeds come from plants that were traditionally grown in human populations, as opposed to the seeds used for large-scale agricultural production? Choices: - old-fashioned seeds - modified seeds - original seeds - heirloom seeds A:
Ans: heirloom seeds
(Q).
Answer the following question given this paragraph: The four types of tissues make up all the organs of the human body. An organ is a structure composed of two or more types of tissues that work together to perform the same function. Examples of human organs include the skin, brain, lungs, kidneys, and heart. Consider the heart as an example. Figure below shows how all four tissue types work together to make the heart pump blood. Q: A structure composed of two or more types of tissues that work together to perform the same function is called? Choices: - Group - order - System - organ A:
(A).
organ
Ques:Answer the following question given this paragraph: Q: What fibres are seen in some vertebrates that twitch at rates far faster than any human muscle? Choices: - fast oxidative fibres - slow twitch fibres - fast glycolytic fibres - skeletal muscle fibers A:

Ans:skeletal muscle fibers
Question: Answer the following question given this paragraph: A star like our Sun will become a red giant in its next stage. When a star uses up its hydrogen, it begins to fuse helium atoms. Helium fuses into heavier atoms like carbon. At this time the star's core starts to collapse inward. The star's outer layers spread out and cool. The result is a larger star that is cooler on the surface, and red in color. Q: What is our sun's next stage called? Choices: - blue giant - white giant - super nova - red giant A:
Answer:
red giant
