Answer:
A. Chelicerates are a group of arthropods

Chelicerates are primitive arthropods having 6 pairs of appendages. 1 oral appendage used for feeding and lack actual mouth parts for chewing up "suck up predigested food". Cephalothorax is the largest and Abdomen contains gills.

Sample A most likely came from the left ventricle, as this is the portion of the heart that receives freshly oxygenated blood to be pumped to different parts of the body. Oxygenated blood is blood that has had oxygen bounded to it by hemoglobin (a pigment made of iron found in red blood cells). The oxidation of this blood by the iron in the hemoglobin gives it the RBC bright red look. This blood containing the bright RBCs in transported to the left ventricle from the lung, after which it is spread throughout the body. Hence, in normal conditions of the heart, the Sample A most likely came from the left ventricle.
B. is the answer because the nervous system send nerves down your body telling your hand to move its a reaction to the pain of the hotness your felling
The nucleic acids that moves the code for protein synthesis from the nucleus to the ribosomes is : D. mRNA
This code is most commonly known as the Transcript, which is very important in DNA forming process
Hope this helps
