Explanation:
They are opposites because they are the same chemical reaction but reversed. Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).
The only correct answer in this case is B - a stroke.
None of the other answers could be counted as correct here.
While A - a heart attack is conceptualy similar, when we're talking about a heart attack, we're talking about not enough oxygen that gets delivered to the heart - because something is blocking it.
C - hypertension on the other hand means someone has a higher blood pressure than is usual for a regular human being, which puts more strain on his cardiovascualr system.
and D - atherosclerosis doesn't come even close to be correct :)
Answer:
(1) Conduction - (B) A seagull stands on ice and loses heat through its feet.
heat is lost due to direct contact.
(2) Free Convection - (E) A dog stands outside on a cold, but windless, day and loses heat to the air. There is heat transfer due to difference in temperatures.
(3) Forced Convection- (A) A bear stands in a cold flowing stream and loses heat to the water. Here we consider buoyancy effects.
(4) Evaporation- An athlete sweats while running a race. water turns evaporates from the body taking a away heat.
(5) Radiation - (C) A lizard absorbs heat from the sun's rays. Sun´s heat travels as radiation.
