1.) Two changes are in the shape and function of the blood cells. Healthy RBCs (red blood cells) are biconcave and can stack, making them able to travel through narrow or curved passageways. However, individuals with sickle cell anemia have RBCs that are more rigid, making them difficult to travel through a lot of passages. Also, they die out more quickly and are more likely to cause blockages and rupture.
2.) As stated above, issues include organ damage due to lack of blood flow and filtration of toxic substances. Another issue, the worst result, is death. This can be caused by a lot of side effects. One can be the blood doesn’t get efficiently to or filter out of the kidneys.

Hi, 

I think the answer you're looking for is already in the question you submitted. However, I disagree that a frameshift could result from the mutation because frameshifts would only happen if there were insertions or deletions in the sequence. For your question, this is an example of a simple point mutation/nucleotide base substitution, and would only result to either a missense or a nonsense mutation. Depending on the bases flanking your mutation, this results to transcribing a different sequence of RNA leading to translating either a different amino acid or a stop codon.

Epithelial tissue always has an exposed outer surface and an inner surface anchored to connective tissue by a thin, non- cellula
Rashid [163]

The basement membrane is the thin, non-cellular structure of connective tissue that separates the lining of an internal surface and external surface from underlying connective tissue in metazoans.

The epithelium is a type of body tissue that covers all internal and exterior body surfaces, lines hollow organs and body cavities, and makes up most of the glandular tissue. The body comprises four types of tissues; depending on the location, connectives, muscular, nervous, and Epithelial, which perform the function of protection, secretion, and absorption.

Some examples of epithelial tissues in your body are the outer layer of the skin called the epidermis, the sweat glands, respiratory tract lining, intestines lining, etc. you can also read more on Epithelial tissue.
