Hello!
You forgot the alternatives!!
Here we have:
<span>a. thymus
b. spleen
c. tissues
d. lymphatic ducts
</span>
The only structure listed above that is not a specific part of the adaptive immune system is the letter c) tissues. The tissues are a group of cells that do the same job: connective (maintain the organs in their place), muscle (produce movement within internal organs), nervous (sensory input, control of homeostasis etc), and epithelial (protection).

Search it up!! it’s a multiple choice questions and all you need to do it search
The first living things on Earth, single-celled micro-organisms<span> or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have </span>first<span> appeared on </span>Earth<span> almost four billion years ago, just a few hundred million years after the formation of the </span>Earth<span> itself.</span>
The first layer is the cell wall.
And the second layer is the cell membrane.I think
The group of choices associated with the question is:
Tyr-Phe-Glu-Asn-Leu
Met-Phe-Pro-Ile-Leu
Val-Ala-Val-Glu-Val
Glu-Asn-Ser-Thr-Gln
Answer:
The correct answer is - Met-Phe-Pro-Ile-Leu
Explanation:
There is various type of amino acid residues that are located in the water-soluble globular protein, depend on the location inside the globular protein, that could be the center of the particular protein or interior of the protein.
Met-Phe-Pro-Ile-Leu is the amino acid residue among given options is the most likely the sequence as all the amino acids are nonpolar in this residue.
Thus, the correct answer is - Met-Phe-Pro-Ile-Leu
