The observation that abnormal cleavage of mannose residues from glycoproteins causes an autoimmune disease in mice supports the role of this structure in the normal immune response. Identify the most likely subcellular site for the deficient or mutant protein in this scenario.
A) Nucleolus.
B) Nucleus.
C) Agranular endoplasmic reticulum.
D) Granular endoplasmic reticulum.
E) Golgi apparatus.
F) Endosomes.
G) Peroxisomes.
H) Lysosomes.
I) Cytosol.
J) Cytoskeleton.
K) Glycocalyx.

K) Glycocalyx

Explanation:

The glycocalyx (also known as pericellular matrix) is a surface that surrounds the membrane cells, this coat is esecially composed by glycoproteins and is found both ineukaryotic and prokaryotic cells. The glycocalyx has many carbohydrates which have diverse cellular functions, including cell recognition, cell adhesion, and intercellular communication

"a scientist studying a whale and its surroundings would need to understand the structure of atoms in case something was negatively affecting the whale or its surroundings."

explanation:

this was from the link provided:

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
