b. Red blood cells that lack nuclei

d. A fully erect posture associated with bipedalism

Explanation:

Eccrine glands can be found on horses, you may have seen horses sweeting. The pressure sensors can be found in other apes too. Fully erect posture is a characteristic of humans, other apes or monkeys may walk sometime like this, but their main locomotion is in 4 extremities. Non nucleated is a characteristic that gives an advantage because more oxygen can be carried inside red blood cells making respiration more efficient.
