Question
Please solve the problem with the circle drawn.
A "deme" is a B) population of a particular species C) a sterile organism that results from related species interbreeding D) an abbreviation for the word "demographics" The statement "Homo sapiens is a polytypic species" means A) there are many different primate species on Earth today B) modern humans evolved from ape-like ancestors. C) people look very different from other species of animals like panda bears and chickens. D) humans have a large number of populations that differ by regional concentrations of expressions. Regional concentrations of similar phenotypes (like nose shape or hair color) in human populations can be explained as a result of A) isolation from other populations over of thousands of years B) limited genetic variation in the founder population of humans in that region C) random genetic mutations that occurred in different populations over time. D) All of these answers are correct A clinal distribution map is B) used to show the concentration of a trait or allele (like blood type) across geographical space C) a chart that illustrates the location of specific populations that do not migrate for any reason. D) a way to demonstrate that evolution has or has not o in a local population A cladogram is a chart that always includes time frames for evolutionary "branching" relationships between species An allele that can cause a "bad" genetic condition is retained in a population if having a single "bad" allele helps protect people against a deadly disease. This is an example of A) heterozygous advantage B) polymerase chain reaction C) auto-immune deficiency D) kin selection Which of the following is an example of an adaptation in the human species? A) short-term hypoxia acclimatization in individuals B) high altitude plasticity over the life time of an individual C) vasoconstriction and vasodilation as body reactions in all people to temperature changes Long, thin limb proportions dissipate heat better than short, thick limbs. This observation is known as B) Allen's Rule C) Gloger's Rule D) Bergmann's RuleExplanation / Answer
ANSWER:
11) B
a deme is a term for a local population of polytypic species that actively interbreed with one another and share a distinct gene pool. When demes are isolated for a very long time they can become distinct subspecies or species.
14) B
Genetically inherited traits often have a clinal distribution
