Answer:
Countries become better at making the product they specialize in. Consumer benefits: Specialization means that the opportunity cost of production is lower, which means that globally more goods are produced and prices are lower. Consumers benefit from these lower prices and greater quantity of goods.
Explanation:
Answer:
Fossil record is used to study macro evolution.
Explanation:
Macroevolution may be defined as the change above the species level. Fossils are the impressions of dead plants and animals buried under the surface of rocks.
Fossils provide the direct evidence of macroevolution. For example : Paleozoic era was dominated by trilobites, crinoids and brachiopods. Rocks that one part of paleozoic era are now contains the fossils of trilobites, crinoids and brachiopods. These species may either extinct or not common in today's world. Thus, fossil record can be used to study macroevolution.
Scientific knowledge refers to a generalized body of laws and theories to explain a phenomenon or behavior of interest that are acquired using the scientific method. Laws are observed patterns of phenomena or behaviors, while theories are systematic explanations of the underlying phenomenon or behavior.Scientific Knowledge is Based on Empirical Evidence Identifies accurate examples of data used for evidence. For example: Much of the data about the seafloor is collected without direct observations. ... For example: the sonar mapping activity graph can serve as a model of the seafloor.Scientific knowledge allows us to develop new technologies, solve practical problems, and make informed decisions — both individually and collectively. Because its products are so useful, the process of science is intertwined with those applications: New scientific knowledge may lead to new applications.Scientific knowledge refers to a generalized body of laws and theories to explain a phenomenon or behavior of interest that are acquired using the scientific method. Laws are observed patterns of phenomena or behaviors, while theories are systematic explanations of the underlying phenomenon.It is derived from perception, learning, and discovery. Scientific knowledge, in particular, is organized in a systematic way and is testable and verifiable. It is used to provide explanations of the occurrence of events.Scientific knowledge is fully objective, verified by independent scientific research. The course of the conducted research, applied research methods and their nature and research issues should be determined objectively by scientists, ie independently of other entities and institutions.
10 ng is the minimum amount of DNA to visualize it on agarose gel. The amount of DNA to load per well is variable. The least amount of DNA that can be detected with ethidum bromide is 10 ng.
Cell utilize this process to transport materials across the cell membrane without the expenditure of energy.
