Scientific method is one of then I'm pretty sure because that's a way of studying the world around you in a series of steps

Exercising doesn't mean you have to spend hours in the gym. Exercises can be done at the comforts of your home too, and there's plenty of exercise available, especially for those who have less time to do so. Just like for example, waiting time. While you are waiting for your clothes in the washing machine to finish, you may use this time to do some basic exercises such as running in place, jumping jacks or carrying weights. It may only take a few minutes, but performing these exercises in less time is better than not doing it at all.
Answer: Rh boold factor is determined by the presnce or absence of a particular erythrocyte protein
Explanation:
The Rh factor is an integral protein of the membrane of red blood cells (erythrocytes) and, by its determination, the blood type RH + or RH- is detected, -regardless of the types of groups known as 0, A, B and AB- .
People who are RH + are those who have this protein in their red blood cells, and people with RH - refer to those who do not have the protein.
The Rh factor (Rhesus) was discovered by Karl Landsteiner and Wiener in 1940.
