Explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Westkost [7]

Answer:

First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.

Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.

In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).

In the skeletal muscle cells of vertebrates, as many as ____________ molecules of atp are produced from one molecule of glucose.
shusha [124]
<span>In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
</span>The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the <span>cytosol, outside mitochondria. </span>

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms
Delvig [45]
<h3><u>Answer;</u></h3>

A. <em>18 hydrogen atoms </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
  • <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
  • Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
