Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases. The animation at right shows a water wave travelling from left to right in a region where the depth of the water is greater than the wavelength of the waves. I have identified two particles in orange to show that each particle indeed travels in a clockwise circle as the wave passes.
Connecting the worlds of engineering and regenerative medicine is no small feat and I hope that our last blog, which connected the human brain and the controller of an automation system, opened your eyes and allowed you to make some realistic associations between two distinct processes. With these blogs, we are propelling the industry forward by familiarizing both engineers and scientists with the worlds of a “different” industry.
Answer:
Environmental Resistance
Explanation:
Environmental resistance can be defined as all the factors including physical factors, chemical factors and environmental factors including biotic and abiotic factors (e.g drought, mineral deficiencies, and competition) limiting the life forms of an organism or kind of organism and impose a restriction on their numerical increase. These factors limit the growth of species in a population.
Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle and Theophrastus tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.
Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.
So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.
Goal of modern classification system:
Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.
Thus modern goal is better in many terms and is more reliable than old classification goals.
Hope it helps!
