Question 3

Saartjie baartman

Answer 3

was a slave for an exhibit. McCoy twins killed themselves because they were slaves

Question 4

Sir francis galton

Answer 4

Question 5

Fran’s boas

Answer 5

He studied head shaped of US immigrants. Also helped form American anthropology association

Question 6

Carleton putman

Answer 6

Thaight I was a bad idea to see people differently because of genetics “bad idea”

Question 7

Caspari

Answer 7

Thaight new physical anthropology no longer supports the idea that races are subspecies

Question 8

Positive natural selection

Answer 8

The tendency of beneficial traits to increase in a population

Question 9

Purifying (negative) selection

Answer 9

Removes mutations as they arise, rather than promoting the spread of new traits

Question 10

Selective sweep

Answer 10

When advantages alleles that are under positive selection sweep through the population and leave distinct patterns of genetic variation in DNA

Question 11

Response to natural environment

Answer 11

Response to cold or warm climates - genetic adaptation to altitude. Also body’s shape

Question 12

Response to biological environment

Answer 12

Lactose tolerance, prevalence of sickle cell anemia in malarial zones

Question 13

Body’s size and shape

Answer 13

Linked to body’s efficiency in responding to hot/cold climates

Question 14

Bergmanns rule

Answer 14

Individuals with greater mass found in colder regions closer to the pols. Individuals found with less mass found in warmer climates

Question 15

Allens rule

Answer 15

The length of arms, legs, and other appendages has an effect on the amount of heat lost to the surrounding environment

Question 16

Phylogenic plasticity

Answer 16

Shifts in body, physiology, behavior, that are dependent on environmental change, (example - a low lander can come up to high altitude and train.

Question 17

Genetic changes

Answer 17

Rather than producing red blood cells, Tibetan highlanders actually produce less. Has to do with altitude sickness

Question 18

Lactose intolerant

Answer 18

Most people stop producing lactase around 2 years of age become lactose intolerant can no longer digest milk.

Question 19

Increase incidence of malaria

Answer 19

Farmland, and out agriculture, as well as our living de city made it easier for bacteria to be moved around. Mosquitos for example

Question 20

Sickle cell anemia

Answer 20

Caused by having sickleing mutation changing the shape of rbc that can get caught in small blood vessels.

Question 21

Race

Answer 21

A group of populations sharing certain characteristics that make them distinct from other groups of populations

Question 22

Subspecies

Answer 22

A group of local populations that share part of the geographic range of species.

Question 23

Population

Answer 23

Smaller or larger groups of populations, restricted to some extent

Question 24

Dermis

Answer 24

Inner layer of skin containing blood vessels glans and nerve endings

Question 25

Epidermis

Answer 25

Outer layer, functions to protect underlying tissue from abrasion drying pathogens and uv damage

Question 26

Keratinocytes

Answer 26

Produce keratin, which protects against water and abrasion

Question 27

Melanocytes

Answer 27

Produce the pigment melanin

Question 28

Innate immunity

Answer 28

Nonspecific defense mechanisms that come into play withing hours of antigens appearance in the body

Question 29

Adaptive immunity

Answer 29

Antigen specific immune response involving the formation of immunological memory that makes future responses more efficient.

Question 30

Antigen

Answer 30

Anything that causes an immune response

Question 31

Pathogen

Answer 31

Disease causing antigen

Question 32

Allergies

Answer 32

Inappropriate response of the body against normally harmless substances in the environment
