-
definition: intersection of altitudes
how to: perpindicular line through angle bisectors - Science differes from other disciplines, such as history and the arts, because science relies on
- testing explanations
- Information gathered from observing a plant grow 3 cm over a 2-week period results in
- data
- A hypothesis
- may be disproved by a single experiment
- The amount of light and temperature are examples of
- factors to which living things respond
- To observe a small, living organism, a scientist must use a (an)
- compound light microscope
- A substance with a pH of 6 is called
- an acid
- Amino acid is to protein as
- simple sugar is to starch
- RNA molecules are made of
- nucleotides
- Diffusion is the movement of molecules from
- an area of high concentration to an area of low concentration
- Plants gather the sun's energy with light-absorbing molecules called
- pigments
- Most plants appear green because chlorophyll
- does not absorb green light
- In the presence of oxygen, glycosis is followed by
- the Krebs cycle
- When the body needs to exercise for longer than 90 seconds, it generates ATP by carrying out
- cellular respiration
- If you want to control your weight, how long should you exercise aerobically each time that you exercise?
- more than 20 minutes
- The energy needed to win a 2-minute footrace is produced by
- lactic acid fermentation
- Why do well-conditioned athletes have to pace themselves for athletic events that last several hours?
- cellular respiration releases enery more slowly than fermentation does
- If a normal cell divides, you can assume that
- it has grown to its full size
- In the P generation, a tall plant is crossed with a short plant. The probability that an F2 plant will be tall is what percentage
- 75%
- How many different allele combinations would be found in the gametes produced by a pea plant whose genotype was RrYY?
- 2
- Unlike mitosis, meiosis results in the formation of
- haploid cells
- DNA replication results in 2 DNA molecules, each with
-
1 new strand
1 original strand - How many codons are needed to specify three amino acids?
- 3
- A mutation that involves one or a few nucleotides is called a(an)
- point mutation
- Biogeochemical cycling ensures that nutrients will be
- circulated throughout the biosphere
- Darwin's concept of evolution was NOT influenced by his
- knowledge about the structure of DNA
