Answer: alpha
Explanation: Alpha particles are fast moving streams of positively charged particles that are shown to be Helium nuclei. They have a mass
number of 4 and an atomic number of 2 and a charge of +2. Alpha particles are represented as 4He2. When 238U92 becomes 234Th90, it emitted a helium nucleus 4He2. The equation for the decay is 238U92 ---> 234Th90 + 4He2.
It's not a mole, it's a gene flow.
1.A control group is important to an experiment because it allows you to eliminate and isolate those variables.
2. Controlling variables is important because slight variations to the experiment set up could affect the outcome significantly
Hope this helps :)
Response would be an epinephrine pen, which basically derived of a triple dose of epinephrine...
You’re confusing me, what exactly is the question
