Answer:
I would say chordates. (Not absolutely sure so double check)
Explanation:
Chordates have a dorsal nerve cord, which is super close to a spinal cord. (Which vertebrates have.)
the body is upright, directly facing the observer, feet flat and directed forward. The upper limbs are at the body's sides with the palms facing forward ( the picture is blurry i cant choose an option )
No lesions in the mouth and throat
Weight increase of 1 lb over 3 days Correct
Temperature change from 100.2° F to 99.2° F
Capillary refill slowing from 2 seconds to 3 seconds
Weight increase of 1 lb (0.45 kg) over 3 days
Rationale: Vomiting results in fluid volume deficit. The most accurate method of evaluating fluid volume increase (the desired outcome) is weight. A temperature decrease is not reflective of fluid volume increase. Increasing capillary refill time is indicative of a fluid volume decrease, not an increase. The absence of mouth ulcers would allow the child to drink without pain but does not reflect a fluid volume increase.
