If you broke the distal end of two bones that articulate the carpals, which bones did you break?
Metacarpals and phalanx
Humerus and ulna
Ulna and radius
Humerus and radius
The Correct Answer is C
The bones that articulate with the carpals are the distal end of the radius and the distal end of the ulna. These two bones form the wrist joint with the carpals. Therefore, if you break the distal end of both the ulna and radius, it will result in a wrist fracture. This type of injury is also known as a distal radius and ulna fracture.

Explanation
DNA is a double-stranded macromolecule made up of nucleotides that carry genetic information. The sequence of nucleotides in DNA determines the genetic code, which controls the development and function of living organisms. Chromosomes are structures made up of DNA and proteins that carry genes. Nucleotides are the building blocks of DNA and RNA. RNA, on the other hand, is a single-stranded macromolecule that plays a key role in protein synthesis by carrying genetic information from DNA to ribosomes.
Correct Answer is A
Explanation
Also known as platelets, are cell fragments in the blood that play a crucial role in blood clotting or coagulation. When a blood vessel is injured, thrombocytes are activated and clump together to form a platelet plug that stops the bleeding. They also release substances that promote blood clotting and help to repair the damaged blood vessel. Therefore, the function of thrombocytes is important in preventing excessive bleeding and promoting wound healing. Options a, c, and d are incorrect because they do not describe the function of thrombocytes.
