It is: D. it produces male and female sex cells.
Explanation:
Answer:
Oxytocin
Explanation:
The release of oxytocin is signaled by the fetal brain about 38 weeks after conception. Oxytocin is also called birth hormone as it stimulates uterine contraction.
The uterine contractions stimulate the release of more oxytocin through a positive feedback loop. Oxytocin stimulates contraction of the smooth muscles in the wall of the uterus which in turn finally leads to childbirth.
Anaerobic exercise is one situation that would cause a buildup of lactic acid in human muscle cells. As the cells switched over from aerobic respiration to fermentation in order to produce ATP, lactic acid would be produced in relatively large quantities as a byproduct. This allows NADH and FADH2 electron carriers to be oxidized without the electron transport chain and would allow Glycolysis to continue.
Answer:
Embryological evidence
Explanation:
Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.
It is the trigeminal. check my spelling though.
