Building Blocks in Life Science Chapters 13-17

Question 1

large proteins with “active sites” that hold molecules with matching shapes for speedy reaction

Answer 1

enzymes

Question 2

consist of proteins in a phospholipid bilayer

Answer 2

membranes

Question 3

Long ago, Miller accepted the evidence that his spark chamber experiment (did/did not) support chemical evolution. He tried other starting materials and conditions: these also seemed to (prevent/ promote) belief that chemicals produced life.

Answer 3

did not; prevent

Question 4

Without seeing either the creator or the creative act, is there any way a scientist could tell whether an object were produced by time and chance or plan and purpose? Explain.

Answer 4

What does it take to recognize evidence of creation? Just the ordinary tools of science: logic and observation. Even when we don’t know who or what the creative agent is, there are cases where “creation” is simply the most logical inference from our scientific observations. For example: A pebble and an arrowhead can be made of the same material. Yet, the rock will show signs of weathering and processes over time. The arrowhead is clearly something deliberately made.

Question 5

regulate what gets in and out of the cell

Answer 5

membranes

Question 6

provide energy to make “build up” reactions go faster than “break down”

Answer 6

ATP

Question 7

The popular slogan “Evolution is science; creation is faith” is (obviously the absolute truth/nearly exactly the opposite of the truth) and is meant to (start/stop) discussion of scientific evidence.

Answer 7

nearly exactly opposite of the truth; stop

Question 8

provides the motion that destroys structure and can bring death

Answer 8

water

Question 9

DNA bases have interlocking shapes forming base pairs G-C and __-__. In RNA, U pairs like T, so interlocking DNA-RNA bases are G-C and __-__. DNA makes “messenger RNA” (mRNA) by DNA-RNA base-pairing, so the DNA for disease-causing HBS (GGACATCTT) would make mRNA sequence _____.

Answer 9

A-T; A-U; CCUGUAGAA

Question 10

provides the motion to molecules that make life possible

Answer 10

water

Question 11

used as a code to “tell” the cell how to make proteins, including enzymes

Answer 11

DNA

Question 12

pass hereditary instructions from one generation to the next

Answer 12

DNA

Question 13

The Bible says living things are made of (not by) “dust,” simple “earthly” substances like the hydrogen, oxygen, nitrogen, carbon, and phosphorus that make up over 95 percent of “living matter.” Write the symbols for these five kinds of atoms: _____, _____, _____, _____, _____.

Answer 13

H, O, N, C, P

Question 14

select which molecules get an “energy boost”

Answer 14

enzymes
