D. Convection heat transfer is<span> caused within a fluid by the tendency of getting hotter and that causes less dense material to rise and colder material to sink caused by gravity, which results in convection heat transfer. Hope this helps </span>
Answer:
The gravitional pull of the Earth
Explanation:
Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Since the earth has more it will cuase you to be, almost attracted by it.
Also, Gravity is inversely proportional to the square of the distance that separates the two bodies. Hence gravity will decrease as one will go higher in altitude, and hence away from the center of mass.
But since your falling from a plane, or some other type of aircraft, your moving closer to the center of mass, hence your gravitational pull get stronger as you falling closer-and-closer to the ground.
Answer: Chlorophyll which are enclosed in the thylakoids captures light energy from the sun. Because of this chlorophyll becomes excited and vibrates and releases free electrons. Because of this vibrations water molecule is also split into H and O2 molecules due to photolysis the splitting of water. Oxygen gas is released out of the leaf as the by product of photosynthesis and H is added to NADPH.
3. In the photosynthetic process under light reaction the plant takes in carbon dioxide and water to produce NADPH and ATP
For plants under dark reaction it occurs in the stroma the outer part of the thylakoids. Since there is no light energy during night time the cell uses ATP and NADPH to fix CO2 to produce sugar molecules and other organic molecules for cell metabolism. The dark reaction cannot function without the products formed under light reaction.
4. The actual or approximate size of an organelle is important because it is an indicator for cellular metabolism such as absorption of food. Larger organelles requires more amount of space inside a cell compared to smaller organelles. Also it requires more energy to sustain cellular activities for much bigger cell organelles compared to smaller ones.
