Describe what might occur if you released a saltwater fish into a freshwater lake?
The water move into the cells of the fish, by way of osmosis. This will cause the cells to swell and burst. The salt in the fish will diffuse out of the fish's cells.
A group of organs that work together to perform a certain function is a(n) .
organ system
Inside the cell the solution is 90% water, 10% solute. Outside the cell the solution is 63% water, 37% solute.
What will happen to the cell?
shrink
Living organisms use ______________ to keep their internal environments within a certain range (they maintain a stable internal condition), despite changes in their external environment.
homeostasis
The solution with the higher solute concentration is said to be_________ .
hypertonic
A_______________ solution is the solution with the lower solute concentration.
hypotonic
An __________________is a structure composed of one or more types of tissues.
organ
A group of organs that work together to perform a certain function is a(n) .
organ system
The diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration is called .
osmosis
The substance, in a solution, that is dissolved is the .
solute
A_________________ is the mixture of a solute in a solvent.soulutionThe substance that does the dissolving in a solution is the .solventA cell with a nucleus is aeukaryoteWhich is the correct formula for cellular respiration?C6H12O6 + 6O2 --> 6H2O + 6CO2Any solution with a higher salt concentration than normal body cells so that the water is drawn out of the cells by osmosis.HypertonicWhat is the correct formula for photosynthesis?6H2O + 6CO2 --> C6H12O6 + 6O2Any solution with a lower salt concentration than normal body cells so that the water is drawn into the cells by osmosis.hypotonicWhich organelle converts the chemical energy in food into a form that cells can use?mitochondriaIf a saltwater fish is placed in freshwater, its cells will swell and eventually burst because of a process calledosmosisOne of the principal chemical compounds that living things use to store energy isATPIf a freshwater fish is placed in saltwater, the salty water is ____________ to the cells of the fish.hypertonicThe movement of water through a selectively permeable membrane from an area of high concentration to an area of low concentration.osmosisWhat do we call different tissues that work together to perform a particular functioncellsDuring heavy exercise, the reason lactic acid fermentation begins is that there isa shortage of oxygenEnergy is released from ATP whenphosphate group is removedA student is collecting the gas given off from a plant in bright sunlight at a temperature of 27oC. The gas being collected is probablyoxygenPlants gather the sun's energy with light-absorbing molecules calledpigmentsIf you continue to increase the intensity of light that a plant receives, what happens?The rate of photosynthesis increases.Which is the following is released during cellular respiration?energyIf carbon dioxide is completely removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars?No sugars would be produced.Which of the following affects the rate of photosynthesis?temperature water lightWhy are 6 carbon dioxide molecules required to make one glucose molecule?Each carbon dioxide molecule contains one carbon atom, and a glucose molecule contains six carbon atomsThe starting molecule for glycolysis isglucoseA substance that moves across a cell membrane without using the cell's energy tends to moaway from the area where it is more concentrated.Cells fall into two broad categories depending of whether or not they contain anucleusWhat type of transport uses energy?active transportHow does ADP store the energy from food in ATP?The energy is stored in the bond between the 2nd and 3rd phosphate in ATP.What are the end products of photosynthesis?glucose and oxygen
