The Great Electron Chase: Describe the flow of electrons from rain falling on your strawberry garden into the strawberry plant (
JulijaS [17]

Answer:

As the rain water is absorbed by the strawberry roots to the leaves, the first step of light independent stage of photosynthesis; Photolysis takes place.

                               H20 = 2H+ + 2e + 2O2.

Generally, the chlorophyll is made up of primary and accessory pigments in its photosystems I and II. These photosystems emitted their electrons through photo activation; these are picked up by electron acceptors; for photophosphorylation in ATPs synthesis. Therefore, these photosystems are positively charged. Hence, PI takes electrons from P II (since it is Cyclic photophosphorylation).Thus P1 is now stabilized, why PII is unstable. To regain its stability, it replaces its lost electrons from the electron of photolysis of water above. This is the electron from the rain water on the (stored in chlorophyll) strawberry. The electron from PI combines with H+and picked up by NAD to NADH. (2H+2e+NADP= NADH).

When the strawberry is consumed, it undergoes digestion and its cellulose metabolized to glucose (the electrons are trapped in the elements C,H,O in the glucose) which flows into the blood stream. As the individual undergoes cellular respiration the glucose with its electrons are the substrate. The glucose, undergoes substrate level phosphorylation (Glycolysis).These electrons are transferred from glucose to the new elements in pyruvate as glucose moves from one stage to another. The electrons are also transferred as part of  H picked up by NAD to NADH. They are transferred from pyruvate to Acetyl, as the latter forms Acetyl Co A with coenzyme A.  

The Acetyl CoA, enters the Krebs’s Cycle, and as, moves from one step to another, these electrons are transferred from one intermediate to another. They are eventually transferred by NADH, FADH2 into the matrix of the mitochondria, where they splits from hydrogen atoms, and carried by electron carriers. As they move from one carries to another, PMF is generated which pumps the H+ across into the inner membranes, to generate the electrochemical gradients for ATPs synthesis, as the protons returns to the matrix.

When these electrons reached the end of the carrier molecule, they are accepted by oxygen the final electron acceptor, to form water. These electrons is transported as water, to the kidney where they are pass through the stages of glomerular filtration, reabsorption, secretion before they are emptied in urine as waste.

Organisms are classified as producers or consumers according to the way they…
Ratling [72]
I believe the answer is 1) Obtain Energy

You can classify them according to the way they get their food because if they eat plants, then they are herbivores. If animals eat herbivores, then they are consumers. Etc.

yaroslaw [1]

Answer:

Fairy penguins (Eudyptula minor), also known as little penguins, are tiny, slate-blue animals found along the coastlines of southern Australia and New Zealand. Not only are they more colorful than most aquatic birds, but they're also notably smaller, growing to be less than a foot tall and about 2.5 pounds.

Is neon different from oxygen?And how is it different? Please explain.
EleoNora [17]

Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.

Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.
