Answer:
Yes, mitochondria transfers energy to the cell.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Muscle cells use more energy than most other cells in the body. Because of this, muscle cells must have more mitochondria.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Answer:
A = 4000 years
Explanation:
Given data:
Half life = 2000 years
Total mass = 100 g
Mass remain = 25 g
Time taken to reduces to 25 g = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At 2nd half life = 50 g / 2 = 25 g
Time taken:
Half life = Time elapsed / number of half lives
2000 years = Time elapsed / 2
Time elapsed = 2000 years × 2
Time elapsed = 4000 years
