First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst.
Scorpion cells undergo aerobic respiration, during aerobic respiration oxygen is used, and ATP is created.
During aerobic cellular respiration, glucose is absorbed with oxygen to form ATP, which can be used by cells. Carbon dioxide and air are formed as by-products. The overall extension to aerobic cellular respiration is: During cellular respiration, glucose and oxygen form ATP.
This process takes place in the mitochondria. So respiration occurs in animals and plants because both have mitochondria.
Aerobic respiration is respiration that requires oxygen while anaerobic respiration is respiration that does not require oxygen. Aerobic respiration consists of several stages, namely: glycolysis, oxidative decarboxylation, Krebs cycle, and the electron transport chain which have been discussed in the previous material.

Answer:
1. DNA and RNA I'm pretty sure
Answer:
It looks like Telephase 1
Answer:
It is difficult to obtain a final conclusion with this information, but it is possible that the sample doesn't contain living organisms whose genetic material is composed of DNA. Another possible reason for this result is that the DNA extraction protocol used in the experiment is not suitable for this sample.
