Answer:
A. Lancelet
B. All chordates
Explanation:
A. Dorsal nerve chord is the only <u>unique feature</u> among all members of <u>phylum chordata</u> (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas <u>snail belongs to phylum Mollusca</u>, <u>grasshopper belongs to Arthropda</u>, and <u>jellyfish belongs to Cnidaria</u>. Dorsal nerve cord runs along the length of organism's body.
B. <u>Gill slits</u> are <u>opening structures</u> to gills through which water passes from pharynx/throat to exterior. Their main purpose is to help filter the food particles available in surrounding water. Although they are typical for amphibians and fishes, chordates also possess gill slits at embryonic stages.

A line graph where the x axis is time and the y is velocity.
Be sure to include increments of measurements.
<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>
Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?
- The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
- Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .
What is cell membrane ?
- All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
A semipermeable lipid bilayer makes up the cell membrane. - The movement of materials into and out of the cell is controlled by the cell membrane.
What are the functions of a cell membrane?
- The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
- second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
