Explanation:
Significance. The cycle's importance is based on the prevention of lactic acidosis in the muscle under anaerobic conditions. However, normally, before this happens, the lactic acid is moved out of the muscles and into the liver. The cycle is also important in producing ATP, an energy source, during muscle activity.
Answer:
A
Explanation:
Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well. Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.
2
This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.

The mantle is a layer inside a planetary bodybounded below by a core and above by a crust. Mantles are either made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. The mantle is bounded on the bottom by the planetary core and on top by the crust. In addition to the Earth, the other terrestrial planets, a number of asteroids, and moonshave mantles.
Answer:
Physical change
Any change to the physical properties of a substance is called a physical change.
Physical changes are usually reversible as no new substance is formed. It is the same substance but with changed physical properties.
Chemical change
A change in which one or more new substances are formed is called as a chemical change.
Usually a chemical change involves a chemical reaction, which forms new products.
Example : Rusting of Iron, or burning wood.
