Explanation:
Enzymes are known as catalysts in a chemical reaction, as they can reduce the time it takes for the reaction to occur by breaking things down. Enzymes are important to living things, because they can be found throughout the body to aid in things like digestion and fighting illnesses. A good example would be putting a Ritz cracker in your mouth and letting it dissolve. This happens because your mouth is full of enzymes that help break food down before entering the digestive system. Hope this helps! :)
For first 30 minutes the rate of change of mass
= M2 – M1/ time taken
= 16 g – 12.5/30
= 0.12 g/min
For first 30 minutes the rate of change of volume
= V2 – V1/ time taken
= 14 -10 cm3/ 30 min
= 0.13 cm3/ min
The "mechanism" is that the chromatids are being separated to show that they are being divided to later be divided in telophase
Answer:
I think its D or B. Not sure but its either one
