In doing the experiment in root pressure, it is always a priority to know and apply precautions in doing experiments. It is best to consider precautions that will be of help and to prevent any damage that could occur. Precautions that are needed to be applied: Safety handling has always been a priority in handling experiments because if this is not done correctly, a lot of things may go wrong. Follow the correct procedure in order to have the correct outcome because not following the instruction could fail the experiment. Lastly, materials needed should be organized and complete in order to provide the needs of the experiment.
Soot is mainly composed of carbon. The black particles is ALL carbon because of the incomplete combustion of the hydrocarbons. Therefore, your answer is B, black carbon.
Answer:
Consider the alleles of the red cow to be CR, CR. Consider the genes of the roan cow to be CR and CW.
CR CW
CR CRCR CRCW
CR CRCR CRCW
The results of the punnet square show that there is a 50% chance that the offsprings will be red cow. The chances for Roan cow will also be 50%. The chances for white cow will be 0%.
Such kind of phenomenon is termed as co- dominance. In this case, the dominant allele is not fully dominant over the recessive allele.
The Circulatory System is about the Blood and the heart: they deliver oxygen to the rest of the body (except lungs). AFTER they deliver the oxygen they get the waste (Carbon Dioxide) and deliver it to the LUNGs (Respiratory System)
The Respiratory system is about the Lungs, Bronchi, Alveoli, Trachea, etc. They EXCHANGE the carbon dioxide from the blood with oxygen, they do this in the ALVEOLI (a small, grape-like sockets in the lungs).
The Digestive System consist the Esophagus, Stomach, Intestines, Gallbladder, and Anus. They Digest the food, they ABSORB the nutrients from the food we eat and we poop out the UNNECESSARY wastes.
