Answer: Minerals
Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.
In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
One possible strategy would be to find the cane toads natural predators. if the cane toad does have natural predators, then it can control the population by hunting it and etc. one limitation to this however would be that there has to be an balance between the toad and that natural predator. for example, they need to survive off of each other so there can’t be too many of the toads not so many natural predators and vise verse.

Answer:
He found that the planets do not all move at the same speed. (A)
Explanation:
Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal
According to the table above, we can calculate required value:
29x4 + 6x4 + 1x9= 149 kcal/g
