The correct answer is d. all of the above.

About 29 % of the solar energy is reflected back to space by clouds, particles in the atmosphere and by snow or sea ice and about 23 % of solar energy is absorbed by dust, water vapor and ozone present in the atmosphere.  Only 48 % of solar energy passes through the atmosphere and is absorbed by the surface. Thus, approximately 71 % of the total solar energy is absorbed by the Earth system.

The answer is: D. all of the above.

When Earth receives energy from the Sun, some energy is reflected back into space, some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface.

Using the sliding flament theory, explain (or draw) the process of sarcomere shortening. Start from the point where calcium woul
Arte-miy333 [17]

Answer:

  1. Calcium binds to troponin C
  2. Troponin T moves tropomyosin and unblocks the binding sites
  3. Myosin heads join to the actin forming cross-bridges
  4. ATP turns into ADP and inorganic phosphate and releases energy
  5. The energy is used to impulse myofilaments slide producing a power stroke
  6. ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
  7. ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
  8. Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Explanation:  

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing <u>calcium into the sarcolemma.</u> At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join to the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.
