Build several models of his tree house out of different materials, and see which model holds up best to wind, water, and ice.
Answer:
Explanation:
NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.
On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
Answer:
Option 4. Autonomy vs. shame and doubt is correct answer.
Explanation:
Erik Erickson presented theory of personality development which is very popular and acceptable. He divided his theory into 8 sages each having 2 components. I have attached an info graph explaining clearly each stage.
Explanation:
This statement is correct because the concept of integrating body and mind in physical activity was responsible for the expansion of physical activity, in addition to activities that promote only the well-being of the body aesthetically, but as a set of activities responsible for improvement of health, intelligence, emotional, creativity, as well as an instrument of social integration. The practice of physical activity releases endorphins in the brain, which is a natural substance produced by the brain that is associated with well-being, mood and joy, and this effect occurs during and after physical activity.
