Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years
The wings are adapted so they can hover and feed off of flowers.
The beak and tong is modified to extract nectar from flowers with long flower corollas.
Glycolysis requires an investment of 2 ATP, but it yields a total of 4 ATP, netting 2 ATP. So more ATP is produced than is used.
