A detective gathers cell evidence at a crime scene. The victim is a 37 year old man, killed by a blow to the head. Closer examination of the evidence leads the detective to conclude that firewoods was used. Which of the following kinds of evidence BEST supports his conclusion?
a. cells with cell walls found on the victim's head.
b. cells with mitochondria found on the victim's head
c. cells with nuclei found on the victim's head
d. cells with ribosomes found on the victim's head.
e. cells with both a and b found on the victim's head
plant cells do not have mitochrondria
okay but you still didn't answer the question...
To determine which kind of evidence best supports the detective's conclusion that firewoods was used in the crime, we need to analyze the options given and identify which cellular structure is directly related to firewoods.
a. Cells with cell walls found on the victim's head: While cell walls are present in certain types of cells, they are not specific to firewoods. This does not support the detective's conclusion.
b. Cells with mitochondria found on the victim's head: Mitochondria are involved in the generation of energy within cells. Although mitochondria can be found in various cell types, they are not exclusive to firewoods. This does not support the detective's conclusion either.
c. Cells with nuclei found on the victim's head: The nucleus is a critical component of most cells and contains DNA. While this evidence shows that the cells on the victim's head are intact and have a nucleus, it does not directly relate to firewoods.
d. Cells with ribosomes found on the victim's head: Ribosomes are responsible for protein synthesis within cells. While they are found in all cells, their presence does not directly indicate the use of firewoods.
e. Cells with both a and b found on the victim's head: This option includes cells with both cell walls and mitochondria. Since neither of these cellular structures specifically correlates with firewoods, this does not provide the best support for the detective's conclusion.
Therefore, the correct answer would be none of the options provided (a, b, c, d, or e). The given evidence does not definitively support the detective's conclusion that firewoods was used.
