Answer:
The phylum Hemichordata is the one that could form an evolutionary connection between the chordates and non-chordates.
Explanation:
To the phylum Hemichordata belongs a genus that scientists believe could explain how the chordates could evolve from the non-chordates. This genus is Balanoglossus, of the class Enteropneusta.
Balanoglossus is similar to a worm, whose habitat is the seabed, and like other hemicordates it has a stomach, a structure that forms part of its digestive system and fulfills the functions of a spine.

Answer:
<em>Staphylococcus</em> is a gram negative bacteria that belongs under family Staphylococcaceae.The name is given as their body shape is spherical(Cocci).
Explanation:
The important characters of Staphylococcus are-
- <em>Staphylococcus </em>are facultative anaerobic organism.
- They are spherical in shape.
- As they are gram positive bacteria, thus the cell wall is prominant and easily stained with crystal violet and they are grown in bile salts.
- They are capable of producing coagulase enzyme that cause blood clot.
- These bacteria divides along two axes and thus form clump of bacteria.
Difference between <em>S. aureus</em> and <em>S.epidermis-</em>
- <em>S. aureus</em> is round in shape where as<em> S.epidermis</em> is spherical in shape.
- <em>S. aureus</em> is a opportunistic pathogen that cause different diseases like skin infection where as<em> S.epidermis</em> is non pathogenic bacteria.
- <em>S. epidermis</em> form white raised cohesive colony with 1-2 mm in diameter whereas, <em>S.aureus</em> form golden yellow color colony.
- <em>S.aureus</em> causes hemolysis when it is grown in agar plate whereas <em>S.epidermis</em> is not hemolyse in blood agar plate.
