Answer:
b. Phalanges
Explanation:
The metacarpals are the five bones that form and support the hand and articulate distally with the proximal phalanges, the bones that form the fingers, and proximally with the distal carpals. The carpus is composed of eight bones that connect the hand with the forearm, those bones are divided into distal and proximal, distal means far from the midline and proximal means near to it. Therefore, the distal part of the carpus is the one that articulates with the metacarpals.
The ulna and the radius are the bones that form the forearm and articulate with the proximal carpals.
Answer:
The false statement is : d. the axial skeleton includes the vertebral column and upper limb
Explanation:
The human body is composed of a hard structure of bones called skeleton. The human skeleton is divided into : appendicular skeleton portion and axial skeleton portion.
The appendicular skeleton consists of the upper and lower limbs, the pelvic and pectoral girdles.
The axial skeleton makes up the central axis of our body and includes the skull, thoracic cage or the rib cage, sternum and the vertebral column.
Therefore, the statement d is false. As the axial skeleton does not include the upper limbs. The appendicular skeleton includes the upper limbs.

Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%
