<span>A fossil leaf that is made only of carbon preserved between two rock layers is called carbon film fossil.
</span>Characteristic of the carbon film fossils is that they are primarily composed of carbon. The fossil leaf has usually lost <span>internal components (cell walls and internal cell structures ).</span>
<span>The answer is C.glycolysis ® Krebs cycle ® electron transport chain. There are 3 stages of cellular respiration: 1. glycolysis when glucose is broken down to pyruvate in the cytoplasm; 2. Krebs cycle when Acetyl CoA and oxaloacetate form a 6 C-atoms compound; 3. Electron transport chain when hydrogen molecules removed through previous stages are pumped to the chain and energy is produced.</span>
Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150
= 0.108 moles
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
= (0.108 × 2)
= 0.216 moles
But, 1 mole of Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
0.216 moles × 77
= 16.632 g
The provided question is incomplete as the options are not given, however on the general knowledge the answer is given:
Answer:
The correct answer is - cytoskeleton, plant cell wall, plasma membrane.
Explanation:
The cytoskeleton is the component that helps in the provided different functions in an organism such as maintaining cell shape, cell signaling by filament systems regulation, and facilitate movement and support.
The plant cell wall also helps in providing the cell to maintain its shape and offers the structural support and cell to cell communication is done by the plasmodesmata that also helps in the movement of the small molecules to transfer from one to another.
The plasma membrane has specific receptors present on them that help in the cell signaling, plasma membrane is semi-permeable and so are able to transport the molecules selectively or with the help of transport protein.
Thus, the correct answer is - cytoskeleton, plant cell wall, plasma membrane.
