Answer: Antigens
Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).
Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
Answer:
1. Brain imaging such as CT scans or MRI's can provide evidence of a brain tumor.
2. Brain tumors are hard to treat because of where they are. The brain is the most delicate organ we have. The nerves, veins, blood vessels and more can make treating the tumor very difficult. Brain surgeries can be so complicated when it comes to tumors because any wrong moves and someone can be impaired for life.

I am going off my general knowledge here. I am not entirely sure but I am trying my best to help. Please let me know if it was close or not.
Answer:
In the explanation. :)
Explanation:
Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.
Hope this helps, have a great day!
Show them a glass of water.
<span>tell them that the water is obviously in 3d because its not flat. Because this water takes up space in this glass it has a volume </span>
<span>Say anything that's 3d has a volume, even a 3d movie possibly. I know SPY KIDS 3 came out and some of the characters or things would jump off the screen. Since they aren't flat like a normal tv they have a volume</span>
