Answer;
-Skin cells do not need crystallin for their function.
-Skin cells have the crystallin gene but do not express it.
Explanation;
-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.
-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
B. synapomorphy
A synapomorphy is a shared apomorphy that distinguishes a clade from other organisms.
A clade also known as monophyletic group, is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life".

Answer:
See the answer below
Explanation:
Since bacteria are prokaryotes, they have no nucleus and membrane-bound organelles. The outside of a bacterial cell is protected by a structure called a capsule. The cell wall provides a rigid structure that gives the cell its shape. The cell membrane helps to transport ions, nutrients, and waste. The plasmids allow DNA to be transferred from one bacterium to another.
<em>The bacteria are microscopic organisms that are generally classified as prokaryotes. The prokaryotes lack nucleus and other membrane-bound organelles, unlike the eukaryotes. The bacteria cells are enclosed in a protective structure known as the capsule. Immediately after the capsule is the cell wall whose components vary depending on whether the bacteria is Gram-positive or negative. </em>
<em>Towards the innermost part of the cell, after the cell wall is the cell membrane. It acts as a channel for the transport of materials in and out of the cell. Some bacteria cells have short, circular, extrachromosomal DNA known as plasmids which can be transferred from one cell to another.</em>
