Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
Hello!
For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing.
This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.
For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on.
Have a nice day!
Answer:
In biotechnology, the recombinant DNA technologies have shown to be very useful to produce genetic combinations capable of improving a specific trait. In consequence, these technologies have important applications in different fields ranging from agricultural biotechnology to medicine and industry.
