Term

List the steps of SALI in order.

 

Definition

1. Orientation

2. Safety

3. Use

Term
How much solvent must you add to 1 mL of a 50% solution to make a 10% solution?
Definition

C1V1=C2V2

(1 mL) (.5) = (X mL) (.1)

5 = X mL

 

5 mL - 1 mL (the initial amount ) = 4 mL added

Term
How much NaCl (MW = 58.4 g/mol) should you add to water to make 100 mL of a .01 M solution?
Definition
58.4 g/mol * .01 mol/L = 5.84 g/L * .1 L = .584 g
Term
What is the minimum volume that a p10 micropipet will uptake?
Definition
5x10^-4 mL
Term
An organized group of cells, working together as a functional unit is defined as ___?
Definition
Tissue
Term
Which plant clade has the greatest number of species and is the most abundant on land?
Definition
Angiosperms
Term
The anther is located in the ___ of a flower.
Definition
Stamen
Term
The meristem of a plant is comprised of what?
Definition
Tissue whose cells reproduce as long as the plant lives.
Term
Carnivorous plants digest ___ to obtain ___. They live in ___ soil.
Definition
Carnivorous plants digest insects and small vertebrates to obtain nitrogen. They live in acidic soil.
Term
True or false? Hair on plants was adapted to fight off the cold.
Definition
False, it was adapated to diffract sunlight and is common among xerophytes. 
Term
Biotic factors are ___ and abiotic factors are ___. 
Definition
Biotic factors are living and abiotic factores are not living.
Term
What do aerenchyma do?
Definition
They allow for gas exchange within submerged tissue of the plant.
Term
What are pneuomatophores?
Definition
They are roots which protrude from the ground.
Term
What happens during a type I error? Is it a false negative or a false positive?
Definition
In a type I error, the null hypothesis is rejects and the alternate hypothesis is accepted when it should not be. This is a false positive.
Term
What happens during a type II error? Is it a false negative or a false positive?
Definition
In a type II error, the null hypothesis is rejected when the alternate hypothesis should be accepted. This is an example of a false negative.
Term
What is the difference between a positive and negative control?
Definition
In a positive control, a known result is produced. In a negative control, there is no result from the treatment.
Term
What does the P value obtained tell you?
Definition
The P value is the chance that the results are due to change; the chance the the null hypothesis is correct.
Term
Why are samples used in experiments?
Definition
Samples are used to differentiate between random variation and variation among treatment.
Term
What are advantages of closed circulatory systems compared to open circulatory systems?
Definition

Closed circulatory systems can:

1. Transport blood rapidly and to specific tissue

2. Keep blood and organs separate

3. Support higher levels of metabolism 

Term
Why is segmentation important in animal evolution?
Definition
It has allowed organisms to alter their body in complex ways.
Term
Earthworms have a ___ skelton and movement of ___ muscles allow it to move.
Definition
Earthworms have a hydrostatic skeleton and movement of its longitudinal muscles allow it to move.
Term
The crop in a cockroach is equivalent to a ___ in a rabbit.
Definition
The crop in a cockroach is equivalent to a stoumach in a rabbit.
Term
What type of tissue is responsible for secreting digestive enzymes?
Definition
Epithelial
Term

Definition
Phylogeny is the evolutionary relationship among organisms.
Term
What is an anthropod?
Definition
An invertebrate with a chitinous exoskeleton.
Term
What is cephalization?
Definition
Cephalization is when the nervous system develops on a certain side of the organism.
Term

Definition

1. Foot

2. Visceral mass

3. Mantle

Term
The segment of a population all born at the same time is called a what?
Definition
Cohort
Term
If a birth rate is x, then the intrinsic rate of increase is what?
Definition
x
Term
When a population is at its carrying capacity (K), what is true about the birth rate and the death rate?
Definition
The birth rate = death rate when the carrying capacity is at its K.
Term
What does a mortality rate of 1.00 mean for a certain age interval?
Definition
It means 100% of the organisms in that age interval will die before they reach the next age interval.
Term
What is fecundity?
Definition
Fecundity is the number of offspring produced by a cohort.
Term
What does an operon consist of?
Definition
An operon consists of a promoter, an operon and two or more genes.
Term
True or false? Plasmids are integrated into the host's genome.
Definition
False, the genome is separate from the plasmid of a cell.
Term
True or false? Recombinant DNA is effective in altering traits controlled by multiple genes.
Definition
False
