Process of Electron Transport Chain (ETC), is a series of transferring from electron donors to their acceptors.  It basically means a transfer from high energy molecule to a low-energy molecule.  This process of extracting energy by transfer is classified as a chemical reaction and we see it is the path taken of cellular respiration (NADH) and FADH2) and in photosynthesis, NADPH.  It starts with an electron, NADH and FADH2, when the electron donors release a proton gradient and it creates an imbalance.  Think of it as a see-saw with one heavy person on one end and a lighter one on the other end.  The protons actually attempt to defuse back across this see-saw of a membrane and it releases energy during the cross over which we call Chemiosmosis.

The light-independent reactions of photosynthesis need
Advocard [28]

Light-independent  reactions are the second stage of photosynthesis. They make sugars. Light-independent takes place in the stroma and doesn't require light. They need carbon dioxide (CO2) from the atmosphere to build the sugars. These sugars are used to build starches and cellulose in a cycle of chemical reactions.

loris [4]

Answer:

10. View the slides on the PowerPoint to match each of the cell structures with the correct letter labels for

each of the following cells.

Elodea Cell Cell wall _B____ Chloroplast _A___ Area of vacuole _C__ Onion Cell Cell wall _B__ Nucleus __A_ Mitochondria _C__ Cheek Epithelial Cell Cell membrane _B__ Nucleus __A_ BacteriA Bacterial Cells. View the bacterial cells on the PowerPoint and identify which cell (A, B, or C) is: Coccus ________B____ Bacillus ______A______ Spirillum ______C______ Protista Amoeba can move via the extension of finger-like projections called pseudopodia

Explanation:

Amoeba can move via the extension of finger-like projections called pseudopodia, what prevents plant cells from moving in the same fashion?

Ans: The plants that prevent the information of pseudopodia have rigid cell walls. which is unlike to amoeba.  

How does the euglena compare to both plant and animal cells (i.e. - explain what structure(s) might make it similar to plants and what structures might make it similar to animals).

Ans: Euglena are similar to plants because they both have chloroplast and are similar to animals because  neither has a cell wall.

how do engineers use models and earthquakes simulations to test designs for earthquake resistant buildings and structure
Oksana_A [137]

In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.

<u>Explanation:</u>

They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.

Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.

Dafna11 [192]

Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "

The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.

Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.

Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.

Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.
