Phylogeny

You are a chordate. What four unique characteristics do all chordates possess during some point in their development? List when during development (gestation) each of these traits can be seen in humans.

The 4 unique characteristics are what I have listed below, but I can't seem to find anything on "when" these traits can be seen during developement.

1. Notochord

2. Dorsal, hollow nerve cord

3. Pharyngeal gill slits

4. Muscular post-anal tail

1) Which characteristic is not possessed by all Chordates at some time during their life?

a) notochord

b) pharyngeal slits

c) post-anal tail

d) dorsal hollow nerve cord

e) vertebral column

2) Sponges, adults and larvae, do not ____________________________.

a) eat other organisms for food

b) move by their own processes

c) have multicellularity with tissues and organs

3) ____________________ are the radial symmetric, Eumetazoa?

a) Chordates b) Mollusks c) Arthropods d) Cnidaria e) Flatworms

4) Divergence of the bilateral animals was about 630 million years ago and one difference defining this split is ‘digestive system development’ with __________________ having their mouth develop first and their anus last. a) Protostomes b) Deuterostomes

5) Tunicates and Lancelets are _________________ although they are not among the best known types of this well known animal subgroup.

a) Chordates b) Mollusks c) Arthropods d) Cnidaria e) Flatworms

6) The spinal cord and brain of Vertebrates evolved from the _____________________ of ancestral Vertebrates and Chordates

a) notochord

b) pharyngeal slits

c) post-anal tail

d) dorsal hollow nerve cord

e) vertebral column

7) Which subgroup of Animals is a Deuterostome?

a) Arthropods b) Roundworms c) both a & b d) Echinoderms e) Annelids

8) Which subgroup of Animals has growth with molting (ecdysis)? Ecdysis is to shed an external protective layer of chitin as body size increases.

a) Arthropods b) Roundworms c) both a & b d) Echinoderms e) Annelids

9) The distinction of Animals as ‘vertebrates’ and ‘invertebrates’ continues to be of great convenience; however, ________________ the only subgroup with ‘vertebrates’ also has ‘invertebrates’. a) Arthropods b) Echinoderms c) Chordates

10) Which characteristic is not possessed by all Chordates at some time during their life?

a) notochord

b) pharyngeal slits

c) post-anal tail

d) dorsal hollow nerve cord

e) vertebral column

Discuss one characteristic that distinguishes living from nonliving things and provide an example of that characteristic.

What is a characteristic that distinguishes bryophytes from the other plant phyla?

8. In guinea pigs, short hair is dominant to long hair. What are the genotypic and phenotypic ratios of a cross between a heterozygous short haired guinea pig with a long haired guinea pig?

Which of the following is false regarding the processes of cell death - apoptosis and necrosis? A. Apoptosis results in leakage of cellular components through holes in the plasma membrane B. Atherosclerosis can be caused by inappropriate activation of necrosis C. Necrosis can be induced by heat stress, hypoxia, and pathogen infection D. The contents of apoptotic cells are recycled for the creation of new cellular material
