nuclear weapon testing.. hope that was the answer you needed
b. a layer of molten metal.
c. a layer of hot rock.
d. a layer of rock that forms Earth’s outer skin.
The correct answer is - a. a dense ball of solid metal.
Earth's inner core is the layer of the Earth that is the most dense, has the biggest mass, and is the one that mostly creates the gravitational pull of our planet. It is thought to be consisted of metal, solid one, but under enormous pressure and temperature. The metal that dominates in here is the iron, and it is accompanied by nikel. The inner core is essential for the life on Earth as it affects everything that happens on its surface. It is getting weaker over time, and once it is in function anymore the life on Earth with vanish, luckily this will be in the far future.

Answer:
d
Explanation:
Answer:
b. 15% nitrogen, 30% phosphorus, 10% potash (potassium)
Explanation:
The marks on the packages of the fertilizers are telling us what is their content. The system used id the N-P-K ratio. The N-P-K ratio is giving us information about the chemicals from which the fertilizer is made, and the percentage of each of them. N stands for nitrogen, P stands for phosphorus, and K stands for potash (potassium). In this case we have 15-30-10. This will mean that the percentage of nitrogen is 15%, the percentage of phosphorus is 30%, and the percentage of potash (potassium) is 10%, meaning that we have a fertilizer that is high on phosphorus content.
The fertilizer grade 15-30-10 corresponds to 15% nitrogen, 30% phosphorous, and 10% potash (potassium), respectively. These nutrients play crucial roles in plant health, growth, energy storage and transfer, along with various cellular functions. The fertilizer type should be chosen based on the plant's specific needs and the existing nutrients in the soil.
The numbers on a bag of fertilizer, or the fertilizer grade, represent the percentages of Nitrogen (N), Phosphorous (P), and Potassium (K), respectively. So, in the case of a 15-30-10 fertilizer, the correct combination would be b. 15% nitrogen, 30% phosphorous, 10% potash (potassium).
Nitrogen is crucial in many of a plant’s biological processes and is a major component of proteins, nucleic acids, chlorophyll, and other cell components. Phosphorus helps plants store and transfer energy. Potassium, also known as potash, is important for overall plant health due to its role in the functioning of cell membranes and its involvement in photosynthesis as well as other cellular processes.
Thus, the composition of a fertilizer should be tailored to the nutritional needs of the specific plant and the nutrient content of the soil in which it is being grown.
