Answer:
The correct answer is B. Combustion is a chemical change. When a substance is burned, it forms new substances. Therefore, combustibility is a chemical property because it can only be observed when a substance undergoes a chemical change.
Explanation:
Hope that helps!
Answer:
The answer would be "A substance combusts (burns)".
Explanation
All of the other options are basic physical changes that don't alter the substance on a molecular level, whereas burning a substance permanently changes the molecular makeup.

Please pick me as the brainiest. It would make my day
I am 100% sure that the correct Answer is:
Convection current
Please do have a great rest of your day!
The cycle that powers the ocean currents, weather, and tectonic plates it called convection current. The correct option is d.
What is convection current?Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.
Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.
Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.
Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.
Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.
Thus, the correct option is d.

What is a Monohybrid cross?A monohybrid cross is the hybrid of the two individuals with homozygous genotypes or heterozygous genotypes which result in the formation of opposite phenotype for a certain genetic trait. The cross between the two monohybrid traits such as flower color or plant height is called a Monohybrid Cross.
When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.
Therefore, the correct option is A.

30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.
