We have collected a blood sample from a crime scene. We want to know if it is the blood sample from the victim. When typing the blood you find that the blood clumps (coagulates) with anti-A serum and anti-Rh serum. The victim's blood type is B-. Is this the victim's blood?
No. This is an unknown sample, possibly a suspect sample. The victim's blood is A+.
If we remove a mitochondria from a plant cell, what biological process would stop?
Subject: Cognitive Science
In many cases, observers may think that they have noticed every detail in a situation (car wreck, classroom fight, chaotic food court), but when questioned, they seem to have missed a very obvious detail because they were so focused on another detail. A wonderful example of this is the video with basketball players and a gorilla. While observers count the basketball passes, they completely miss a gorilla walk right through the court! What cognitive science phenomenon is this referring to?
needs and Emili will reply soon.
