When the M phase begins during the cell cycle, it starts with prophase
Answer:
after meiosis, each new cell will be genetically different due to random exchanges of chromosomes.
Answer: Answer below
Explanation: pH is a measure of the acidity or alkalinity of a solution. What the pH scale measures is basically the concentration of hydrogen and hydroxyl atoms in a solution. So, the last option is the answer. Another thing to keep in mind is solutions with a pH under 7 are acidic, solutions with a pH of 7 are neutral, and solutions with a pH over 7 are alkaline or considered a base. I hope this helped! Good luck:)
Answer:
The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.
Rate of reaction= Amount of substrate utilized or product formed/ Time taken
Explanation:
Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.
Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.
Answer:
The mechanism by which organisms use oxygen to break down food molecules in order to obtain chemical energy for cell functions is known as cellular respiration. In the absence of oxygen, cells can generate energy by fermenting food, a mechanism known as anaerobic respiration.
