The pinkish hue of individuals with fair skin is the result of the crimson color of oxygenated hemoglobin (contained in red blood cells) circulating in the dermal capillaries and reflecting through the epidermis- is a <u>true</u> statement.
Explanation:
The color of skin of an individual is due to the presence of three main pigments present in the integumentary system – melanin, hemoglobin, and carotene.
Melanin released by the melanocytes gives a black to brown complexion depending upon the number of pigments present.
Carotene obtained through dietary sources gets accumulated in dermal layers and gives a yellow-orange tinge to the complexion.
The hemoglobin, which contains the red colored pigment ‘heme’ is the reason for the pink hue of fair skinned people. This hemoglobin present in the dermal capillaries running through the entire length integumentary system adds the unique pink hue to the fair complexion. So higher levels of oxygenated blood and skin blood perfusion lead to bright skin coloration.

The binary fission , is the asexual reproduction which is found in prokaryotes. In binary fission a cell divide into two daughter cell. Amoeba is the best example of binary fission in which gentic material is divide and via mitotic division further cell is divide into to daughter cell . So we conclude that, the result of binary fission is formation of daughter cell.
Answer: Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
