Answer:
a. Plum pudding model
Explanation:
The plum pudding model of the atom was proposed by J.J. Thomson. It was the model he derived from his experiment on the gas discharge tube.
J.J Thomson was the first person to discover electrons which he called cathode rays because in the discharge tube, they emanate from the cathode.
- This led him to suggest the plum pudding model of the atom.
- The model reflects electrons being surrounded by a volume of negative charges.
The enzymes of the Krebs cycle are located in the matrix of the mitochondria.
Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle connects carbohydrate, fat, and protein metabolism so the products and intermediates from different metabolic pathways come to this cycle. Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
f(x) = |x-4| + 2
|a| ≥ 0 ∀ a∈R
That means the minim of the function will be when |x-4|=0 ⇒ x = 4
f(4) = |4-4|+2
f(4) = 2 ⇒ M(4,2) - minim point
<em>We notice that the function f is ascending for x ∈ [4,+∞) and is descending for x ∈ (-∞,4]</em>
Because the function is linear,the sketch of the graph will be 2 lines with the intersection in the point M(4,2) (in our case).
Let's find f(0) = |0-4|+2 = 4+2 = 6 ⇒ N (0,6) is the intersection of the function with Oy axis. (now we can sketch the graph only for x ∈(-∞,4] )
Now let's calculate the function for a value bigger than 4 : for example f(5) = 3 ⇒ P (5,3) ∈ Gf
So you can see the graph in the picture.Have a nice day :)
