Density={ \frac {Mass}{Volume} } \\ \\ Volume={ \frac{Mass}{Density} } \\ \\ Volume={ \frac{20g+20g}{7.87g/cm^3} } \\ \\ Volume=5.08\ cm^3 \\ \\ \\ \\ Volume\ of\ larger\ cube=5.08\ cm^3

A grass starts with 30,000 kJ of energy. How much energy would a cheetah acquire after it ate a zebra that consumed the grass?
IrinaK [193]
In every trophic level, only 10% of energy is passed on.
Grass, with <span>30,000 kJ of energy, is eaten by a zebra.
Zebra then has 10% of 30,000 kJ from the grass, which is 3,000 kJ of energy.
Cheetah then eats the zebra, gaining only 10% of 3,000 kJ of energy of the zebra. Finally as conclusion, cheetah has 300 kJ of energy after having acquired the zebra.</span>

aleksklad [387]
The answer to this question would be: <span>b.electromagnetic or weak nuclear
</span>
The electromagnetic force can be repulsive or attractive because it was influenced by the magnetic charge. The same charge (positive with positive) will be repulsive but different charge will be attractive(negative and negative). The gravitational force will always be attractive, not repulsive. 
Weak nuclear can do both like electromagnetic force.

I am trying to determine reactants going into the electron transport chain. Is this right?
irina1246 [14]

Answer:

Yes, this is correct.

Explanation:

  • In each glycolytic pathway, glyceraldehyde 3-phosphate dehydrogenase produces 1 molecules of NADH as a result of reduction of NAD+.
  • Pyruvate dehydrogenase converts pyruvate to Acetyl CoA producing 1 molecule of NADH per pyruvate oxidized.
  • In Kreb's cycle, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and malate dehydrogenase reactions produce 1 molecule of NADH each. Furthermore, succinate dehydrogenase reaction produces a single molecule of FADH2 per FAD reduced.
  • Since, we began with 2 molecules of glyceraldehyde 3-phosphate, we  multiply the above figures by 2 and get a total of 10 NADH and 2 FADH2.
