B) They are biologically invalid due to clinal variation in genetics
C) Head shape and nasal shape are distributed into discrete groups
D) Most genetic variation among human populations occurs between groups, instead of within groups

B) A cell with a nuclear membrane
C) A cell with no nuclear membrane
D) A cell that has only RNA, lacking DNA

Answer 1

6. c

Blood group AB individuals have both A and B antigens on the surface of their RBCs, and their blood plasma does not contain any antibodies against either A or B antigen.

7. a

The mid-twentieth century racial classification by American anthropologist Carleton S. Coon, divided humanity into five races:

• Negroid (Black) race.
• Australoid (Australian Aborigine and Papuan) race.
• Capoid (Bushmen/Hottentots) race.
• Mongoloid (Oriental/Amerindian) race.
• Caucasoid (White) race.

8. b

Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. ... These organisms are grouped into the biological domain Eukaryota. Eukaryotic cells are larger and more complex than prokaryotic cells, which are found in Archaea and Bacteria, the other two domains of life.

9. b

During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.

10. c

population with most individuals inheriting various combinations of alleles and falling within the middle range of the curve for a particular trait. Examples of polygenic traits include skin color, eye color, hair color, body shape, height, and weight.
