Answer:

a . Fish need 10 ml of water purifier to survive.

Explanation:

Fish need 10 ml of water purifier to survive because the data of 10 ml and 20 ml purifier is the same so it is recommended to use 10 ml purifier. First the data was same but by recording next week data, it shows slightly increase in the value of tank 2 while in the last week, both has the same value so we can concluded that by using 10 ml purifier is enough for the fish to survive.

The medial cord is medial to the axillary artery and is formed by the ______ division of the inferior trunk; it contains portion
SpyIntel [72]

The medial cord is formed by the anterior division of the inferior trunk.

It contains portions of nerves C8-T1.

             The medial cord is present in our neck and is a part of the brachial plexus. It is formed by the anterior division of the lower trunk. It is called the medial because it is medial to the axillary artery.

              The medial cord leads to the formation of the medial pectoral nerve, medial cutaneous nerve of the arm, and medial cutaneous nerve of the forearm.

               The nerves labeled as C refer to the nerves affecting the motor system in our neck and upper limb. Thus nerves from C8 work for the motor conventions of our upper limb and neck.

              The nerves labeled as T are spread over our chest, shoulders, and hands. Thus, the nerve T1 works in the upper part of our body.

They are the site for where the tRNA's complementary base pair their anticodons to the codons present on the mRNA strand.

Darya [45]

Not sure if I'm correct but my best guess is the cell membrane seeing as it surrounds the cell itself and is responsible for allowing certain molecules to diffuse in or out of the cell. Good Luck! :)
