Alimentary canal definition ✔✔begins at mouth, ends at anus... digestive system A neuron that transmits impulses from receptors to the spinal cord ✔✔sensory neuron Kinetic energy is at a maximum when the potential energy is... ✔✔at a minimum, for example at the bottom of an incline The more rapid the vibration of sound is, the ____________ the __________ is ✔✔higher, pitch What is the temperature during a phase change from liquid to gas? ✔✔Temperature is constant at 100 degrees Celsius per 1 atm If the temperature rises to 300 degrees Celsius of a gas, the substance would do what? ✔✔It would remain a gas.... it would change back to liquid or condense if heat was withdrawn Neutralization reactions from _____ and _______. ✔✔Water and a salt What organ controls the amount of calcium in the blood? ✔✔Parathyroid - Secreted PTH - Calcium low = release calcium - Calcium high = calcium deposits in bone Celsius to Farenheit equation ✔✔9/5 x Celsius + 32 What tells you that a formula is an alcohol? ✔✔-OH If a car's rate of change of velocity is negative, the car is ________. ✔✔Slowing down What type of solution is an alkaline solution? ✔✔Basic What type of facilitation is needed to go down a concentration gradient? ✔✔Active transport Which of these biological processes includes the other 3? a) cell respiration b) Krebs cycle c) ETC d) anaerobic splitting of glucose ✔✔Cell respiration - Cell resp begins with splitting glucose. Products enter Krebs cycle and then ETC In the classification of 2 organisms, which of the following is the best evidence of a close relationship? a) # and arrangement of bones b) similar sequence of AA and proteins c) similar methods of sexual reproduction d) similar methods of cell respiration ✔✔b) similar sequence of AA and proteins Bending of light ✔✔Refraction What makes up proteins? ✔✔Amino Acids Einsteins equation E=mc^2.... what does c represent? ✔✔c = speed of light More energy is used pushing an object up an inclined plane than lifting the box straight up. Why is this? ✔✔work is done against friction in pushing the box. Energy goes into counteracting friction Tip of crest to tip of crest in a wave is called ✔✔wavelength Most of the work done by the human kidney occurs in the ✔✔nephron Where is food stored in a growing embryo of a bean seed? ✔✔The endosperm... large area inside the embryo
