Building Blocks in Life Science Chapters 1-3

Question 1

Barriers or preferences in the choice of a mate separate some parts of a gene pool from others (e.g. culture and language separates humans; size and temperament separate dogs)

Answer 1

reproductive isolation

Question 2

varieties that consistently look different but still interbreed

Answer 2

morphotype

Question 3

many defects and diseases result from chance changes in heredity called mutations

Answer 3

corruption

Question 4

Members of a kind separating into distinctive subtypes as they “multiply and fill” earth’s environmental diversity (e.g. generalized bears leaving the Ark becoming black, brown, grizzly, and polar bears).

Answer 4

specialization

Question 5

Created kinds may be called ___________, a combination of the Hebrew words bara for ___________ and min for ___________.

Answer 5

baramins; create(d); kind

Question 6

adaptions are design features that suit each organism for its special role in the web of life

Answer 6

creation

Question 7

several small groups separate from a large population, each with percentages of alleless different from those in the original gene pool (e.g. language groups moving away from the Tower of Babel)

Answer 7

genetic drift/founder effect

Question 8

black, brown, grizzly, polar, and panda bears

Answer 8

morphotype

Question 9

Why is it important for Christians to relate God’s world and God’s Word – science and Scripture?

Answer 9

It builds faith and trust in Scripture (the Bible), and it helps believers use the wonders of science to introduce others to the wonders of new life in Christ revealed in God’s Word.

Question 10

look-alike species of fruit files with different chromosome numbers

Answer 10

fertilotype

Question 11

differences in mating ritual or chromosomal rearrangements of the same genes (genons) prevent interbreeding

Answer 11

fertilotype

Question 12

can change appearance when moved to different environments

Answer 12

ecotype

Question 13

Random changes in genes that often change normal genes into alleles producing defects or disease (e.g. sickle cell hemoglobin)

Answer 13

mutations

Question 14

Only a few members of a species with a large gene pool survive a major disaster (e.g. animals aboard the ark)

Answer 14

genetic bottleneck

Question 15

effects on gene regulators make willow trees dwarfs in the Arctic

Answer 15

ecotype

Question 16

flood conditions are ideal for forming fossils

Answer 16

catastrophe

Question 17

land animals saved on the Ark and the immune system healing deadly infections both illustrate God’s deliverance from death and disaster.

Answer 17

Christ
