Tunicates is your answer!
faltersainse [42]3 years ago

The answer is tunicates. Tunicates are commonly known as sea squirts and are in the Chordata phylum, even though they don't have a back bone. Which is really weird. But they just got put into the same category as humans. This is because they have a notocord and a back bone when they are larvae. But they lose all these when they become adults.

Both myoglobin and hemoglobin exhibit cooperative binding to oxygen. True or False
lys-0071 [83]

Answer:

False.

Explanation:

An Haemoglobin molecule  is made up of 4-polypeptides, with each of the polypeptide chain containing an haem group. These haem group can bind with one oxygen atom each.

T<u>he binding of the first oxygen atom  by the first haem group weakens the tertiary protein   structure  of  Quaternary structure  Hb, thus it makes it easier for the second Oxygen atom to bind faster, and the 3rd oxygen very fast and the 4th oxygen atom the fastest.These accelerated binding of the oxygen atoms, facilitated by the first binding O2, is called cooperative binding.It aids oxygen binding capacity and tranport functions  of Hb,</u>

<u />

<u>Myoglobin is an oxygen storage protein in  muscles, and not oxygen carrying molecule, It releases  stored O2 only in condition of low oxygen supply</u>.It has   one haem group in its molecule.Therefore its structural features can  not  carry out  cooperative binding.

1. Which image represents the flow of a longshore current in relation to a sandy beach?​
Dimas [21]

Answer: Option C

Explanation:

When waves of water approach the beach, they do so as an angle because they have been slowed down by the first parts of the beach that they have encountered.

When they hit the beach at an angle, they come back to the water and keep doing so like the movement shown in option D. This constant motion moves the sand and other particles on the beach progressively and the current that does so is the Longshore current which <em>moves parallel</em> to the coastline.
