<span>The options were
a. applied research
b. field research
c. basic research
d. both a. and b.
The answer is C. basic research
Basic research is a research done because of our desire to know more, it doesn't necessarily have any consequences but only helps in expanding our knowledge on the aspect on which research is being done. Unlike applied research it cannot be directly applied to real world but only gives the required answers</span>
Answer:
Here are several reasons for that:
- Every society's population contains a lot of genetic mixture,
- Various racial categories are genetically very much alike,
- The skin color of Caucasian people ranges from very light to very dark.
Explanation:
The fact that there are a large number of similarities between people form different races and varieties between people from same race indicates that there are very little difference between races. (approximately, people form different races only has around 6% of genetic difference)
From the social perspective, differentiating and the racial difference tend to lead to tribalism that make groups of a certain race believe that the others are inferior compared to them. This will increase the risk of conflicts.

A gingival epithelial cell is attached to the basal lamina. Hemidesmosome
type of cell junction allows the cell to attach to the basal lamina.
Hemidesmosomes are very small stud-like structures found in keratinocytes of the epidermis of skin that attach to the extracellular matrix. They are similar in form to desmosomes when visualized by electron microscopy, however, desmosomes attach to adjacent cells.
Hemidesmosomes are also comparable to focal adhesions, as they both attach cells to the extracellular matrix. Instead of desmogleins and desmocollins in the extracellular space, hemidesmosomes utilize integrins. Hemidesmosomes are found in epithelial cells connecting the basal epithelial cells to the lamina lucida, which is part of the basal lamina.[2] Hemidesmosomes are also involved in signaling pathways, such as keratinocyte migration or carcinoma cell intrusion.
