Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
The answer to this question would be A:growth factors
Hope this helped!!
The given statement is false.
The fires are essential to both the grassland and savanna ecosystems. The grasslands and savannas are featured by two seasons, which are sustained by fire, and exhibit species that are impervious to drought. These fires help in following on the sequences and permit for habitats to maintain their resolution.
The African savanna ecosystem refers to a tropical grassland with warm temperatures over a year, and with its highest seasonal rainfall in the summers.
The answer is D: poaching, since it harms wildlife and destroys ecosystems.
Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.
