What are the answers for the 10.6 volcanoes and plate tectonics enrich?PLEASE HELP!
LenKa [72]
Volcanoes and tectonic plates enrich land formation. When a volcanic eruption occurs, materials are brought to the surface that results in the formation of new islands. The actions of converging tectonic plates have created the most beautiful landforms and oceanic trenches. Also, eruptions better the soil quality in a given location. The mineral deposits emitted during an eruption is absorbed by the soil and becomes a lifelong source of nutrition.

explain why the top of an energy pyramid does not have an arrow showing energy going back down to the bottom.
SCORPION-xisa [38]
<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>

Which of the following is NOT true about essential body fat?A.The human body would not function normally without essential body
alina1380 [7]

Answer:

C.The percentage of essential body fat is the same for both males and females.

Explanation:

Among the given statements, only C is incorrect. Typically, on average, women have 5-12% more body fat than men. This has been mainly linked with the female hormones (e.g. oestrogen). Firstly, women can store more fat in their bodies due to the presence of excessive adipose tissues. Secondly, they are suppose to carry a child at some stage of their life, so a better food supply and protection is necessary.

On the other hand, rest of the options are true. Essential body fat is always required by body. It accounts for 3% of total body wight. And, it can be found in organs, bones and muscles at different percentages.
