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.
Answer:
The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.
Explanation:
To help you remember this distinction:
EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.
PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.
I hope this helps and good luck with your assignment.
Answer:
B. bituminous
Explanation:
Bituminous coal is an organic sedimentary rock produced by compression of peat bog material by diagenesis and submetamorphics.
Bituminous coal has low moisture and high carbon content and hence used for the production of steel and cement, coke production an electricity generation.
Coking coal is a type of Bituminous coal are best used as fuel dource in metal industry having very narrow range of volatility and plasticity. Volatility is maintained by smelters to optimize the ease of burn rate, ignition, and energy output of the coal as this determines the burn rate of the coal.
Hence, the correct option is B. bituminous.
Answer:
Any change in the level of a limiting factor will affect the rate of reaction. If the level is too low or too high, the rate of photosynthesis declines rapidly.
