Answer:
b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
Answer:
rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)
Explanation:
Proteins go through the secretory pathway.
The correct answer is A. Pelvis
Explanation:
The ossa coxae, more commonly known as the hip or pelvic bone is one of the main bones in the pelvis which is joined to the sacrum and coccyx. Besides this, the ossa coxae connect the legs or posterior limbs to the spine and therefore it is an important bone for vertebrates placed at both sides of the pelvis. On the other hand, the sacrum is a triangular small bone that is placed int eh middle of the ossa coxae connectin the last vertebras. This along with the ossa coxae and coccyx form the pelvis (set of bones between the spine and limbs). Thus, according to this, the ossa coxae and the sacrum make up the pelvis.
