List 3 factors that can speed up the rate of chemical reactions
zysi [14]

Answer:

  1. Temperature
  2. Greater Surface Area
  3. Catalysts

Explanation:

Temperature

  • An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

  • The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

  • A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Hope this help!!!

Food provides molecules that serve as fuel and building material for all organisms. Plants undergo photosynthesis and make their
zhenek [66]

Answer:

Read explanation.

Explanation:

Like plants, animals also need food for their bodies. But they can't produce their own food. They have to depend on others for food purposes. After eating anything, that don' t go their cells directly. It passes many stages; then, they go the cell as a fuel. From eating to consuming by the cell, many digestive processes happen, such as the degradation of larger molecules to small molecules. Many chemical reactions also occur to covert elements to that form, which can be taken by cells as fuel as the reaction in mitochondria.

This way, men and animals get food as their fuel.

What accounts for the variation Darwin observer among island species
vovangra [49]

Answer AND Explanation:

The islands had different environments, and the organisms had adaptations that enabled the organism to live in those environments. The island had been inhabited by its own kind of species found nowhere else in the world. Darwin also noticed that considerable variation exists between members of the same species. Offspring vary from their parents and between themselves.

What are the advantages of using digital waves over analog signals?
kvasek [131]

Answer:

What are the advantages and disadvantages of digital over analog?

Do you want to learn more about crypto?

“Advantages of Digital Communication. The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog.” In general, digital is far easier to handle and has (virtually) unlimited precision (limited only by hardware constraints and compute time).

Analog computation takes place at a significant portion of the speed of light (the time it takes for an electrical signal to traverse a circuit). However, it is almost impossible to correct completely for noise, and precision is limited to three (or at most four significant digits).
