Answer:
The field-free drift path
Explanation:
In MALDI-TOF, the sample is embedded in a matrix. A laser vaporizes the molecules in the sample with little fragmentation. The gaseous molecules are ionized, accelerated, and sent through a field-free drift path to the detector.
The proteins in the sample have different velocities based on their mass-to-charge ratio.
The fastest ions are those with the smallest m/z ratio.
The field-free drift path increases the separation between the ions, so the smallest ions reach the detector first.
Thus, the ions are separated based on their time of flight through the drift tube.
Answer:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Answer:
Sink
Explanation:
For a substance to float in water, it must be less dense than water. The density of water is 1 g/cm^3. To find the density of the substance, we can do mass/volume, which in this case is 25g/7cm^3. We see that , so the substance would sink.
Answer:
D
Explanation:
Al is a reducing agent because it removes Oxygen from another compound
Mno2 is an oxidizing agent
C They together help recycle important elements in nature.
This is because photosynthesis removes carbon dioxide and creates oxygen while cellular respiration does the opposite. This results in no increase or decrease in any of the elements, and therefore means there needs to be a cycle.
