Answer:
D. Useless
Explanation:
According to Dictionary.com, “in vain” is defined as “without real significance, value, or importance; baseless or worthless.”
Answer:
The living organism is the organism that responds to external stimulus, moves, grows, respire, reproduce, eat and excrete.
Movement - An organism moving from place to place.
Respiration - The release of energy from glucose, occurring in every cell. we respire in order to produce energy
Sensitivity - the ability to detect and respond to stimuli. When we touch something hot, we remove our hand suddenly.
Growth - The production of new cells in an organism.
Reproduction - The process which is used to create offspring similar to parents.
Excretion - The release of harmful substances from the body. We excrete carbon dioxide when we exhale.
Nutrition - Consumption of food for energy. We get nutrition by eating three meals a day.
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
The 2 molecules that carry energized electrons to the second stage of the cellular respiration process, would be D. NADH and FADH2. These are carrying corresponding electrons via or with hydrogen atoms attached to the molecules.
