Experimental designs produce results that contain either quantitative data or qualitative data. Which scenario below produces qualitative data? A) Tim conducts an experiment in which he sees how many fish he can catch by varying the time of day he goes fishing. He fishes on the same boat in the same spot each day for one week. Each day he varies the time he comes out by one hour. He records how many fish he catches each day and analyzes his data. B) Sean notices that his mood is different based on the color of shirt he wears. He decides to conduct an experiment in which he wears a black, red, blue and yellow shirt each day and records his mood in one of four categories: sad/angry/happy/indifferent. He does this for 5 days in each color and records his results. C) Brooke notices that her performance at work is increased when she drinks coffee in the morning. She decides to test her theory by seeing how many emails she can answer in one day. She answers emails for 5 days without drinking coffee and then answers emails for 5 days after drinking coffee on her way to work. She records her answered emails in a data table and compares her results. D) John is using a hair product to help his hair grow. He decides to conduct an experiment on himself and 3 other participants using this hair product. He wants to test the amount of product applied to see how long it takes for one inch of hair to grow. He applies one ounce to himself, two ounces to friend A, and three ounces to friend B. His third friend gets no prod

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
