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.

Taking diphenhydramine and consuming alcohol will lower the activity of the CNS too much.
<h3>What is drug interaction?</h3>
Drug interaction is the interaction that occurs when two drugs are taken concurrently.
Drugs interactions may have positive or negative effects.
Some drugs are taken together to enhance their efficacy.
In the case of diphenhydramine and alcohol, both drugs are central nervous system (CNS) depressants. Therefore, taking both of them together will lower the activity of the CNS too much.
In conclusion, drug interaction is the effect of two drugs when they are taken together.

Gorillas are a predator. They eat food and rarely ever get killed for food. But if we take away their habitat by making buildings and houses then they will die for other causes like hunger. If the gorillas go extinct then the food change will get all messed up. The food they normally eat will over populate meaning the food gorillas eat (like fruit) will over populates and take over the area. That means it will start to take up the space that other plants need to grow. The other plants that other animals will need to eat will slowly start moving away because their food is dying. They will start to go somewhere else and mess up that habitat too. Those animals will eat the food needed by the animals that lived there originally and food will become scarce for animals that all need the same type of resources.
        
             
        
        
        
Explanation:
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
