1 Answer/Comment
Bitter is the taste that may be detected at very low concentration.

Since a large number of natural bitter compounds are known to be toxic, the ability to detect bitter-tasting, toxic compounds at low thresholds is considered to provide an important protective function.

Which statements are true about atmospheric circulation patterns? Wind is another name for atmospheric circulation patterns. Atmospheric circulation patterns keep the temperature of an area constant. Atmospheric circulation patterns are often responsible for hurricanes. Wind that moves from west to east is called a westerly. Air circulation patterns generally follow a straight line. Winds move easily across the plains.
Weegy: Atmospheric circulation is the large-scale movement of air, [ [ and the means (together with the smaller ocean circulation) by which thermal energy is distributed on the surface of the Earth.The wind belts and the jet streams girdling the planet are steered by three convection cells: the Hadley cell, the Ferrel cell, and the Polar cell. While the Hadley, Ferrel, and Polar cells are major players in global heat transport, they do not act alone. Disparities in temperature also drive a set of longitudinal circulation cells, and the overall atmospheric motion is known as the zonal overturning circulation. ] ] User: Select the statement that is false. Ocean currents move cold water from the equator toward the poles. Ocean currents generally flow clockwise in the Northern Hemisphere. Ocean circulation patterns and the water cycle are physical processes. Ocean circulation patterns are caused by their interaction with the atmosphere, pressure, and the earth's rotation. Weegy: Ocean currents generally flow clockwise in the Northern Hemisphere. (More)

Select all that apply. An ecosystem could probably survive without _____. carnivores producers Sun water herbivores climate soil decomposers
Weegy: All of the above. Here is why: An ecosystem, a contraction of "ecological" and "system", refers to the collection of components and processes that comprise, and govern the behavior of, some defined subset of the biosphere. [ [ The term is generally understood to refer to all biotic and abiotic components, and their interactions with each other, in some defined area, with no conceptual restrictions on how large or small that area can be. To many, ecosystems, like any other system, are governed by the rules of systems science and cybernetics, as applied specifically to collections of organisms and relevant abiotic components. To others, ecosystems are primarily governed by stochastic events, the reactions they provoke on non-living materials and the corresponding responses by organisms. So by definition, an ecosystem could have only abiotic components. A sandy beach ecosystem with no life in it. ] ] User: A rainforest is an example of a _____. biome community habitat population Weegy: The answer is A.biome User: Select all that apply. Environmental factors that create different habitats include _____. light temperature animals elevation plants minerals topography growing seasons User: Which of the following can upset the balance of an ecosystem? too much water not enough water too much light not enough light all of the above none of the above User: Ecology that focuses on dynamic changes occurring in one species is _____ ecology. population applied systems Weegy: B.applied User: In a 10 m2 ecosystem, there are 40 possums. What is the population density of possums? 2 per m2 4 per m2 10 per m2 40 per m2 Weegy: In a 10 m2 ecosystem in which there are 40 possums, the population density equals 4 possums per m2. User: The number of organisms that the environment in an ecosystem can handle is called its _____. growth rate carrying capacity population density Weegy: Carrying capacity. Growth rate is how fast the population is ... (More)
