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.

When a person is anxious or fearful, the autonomic nervous system shunts blood away from peripheral veins to the core of the body - TRUE
- Sympathetic stimulation of blood vessels causes arteries and arterioles (resistance vessels) to constrict, increasing vascular resistance and reducing distal blood flow.
- The increased vascular resistance that results from this across the body raises arterial pressure.
- When our bodies shift into superman mode, the second signal is transmitted to the hypothalamus, where it activates our autonomic nerve system,
- which is in charge of the fight-or-flight impulse.
- Our bodies receive an adrenaline boost as well as an increase in heart rate and blood pressure. When you are afraid, you get that rush.
