kinetochores of sister chomatids remain attached throu meiosis I
DNA replication is surpressed b/t meiosis I and meiosis II
Striation
cover muscle fibers with light and dark stripes

Using the typed original DNA strand (AAT-GCC-AGT), what would be the mRNA strand produced?
UUA-CGG-UCA
Biogeography
The study of patterns in the geographic distribution of species
homozygous
having identical pairs of genes for any given pair of hereditary characteristics.
classify
group things based on the features they share
Indeterminate growth
A type of growth characteristic of plants, in which the organism continues to grow as long as it lives.
Hydroxylating agents
* a base modifying factor* ADDS -OH
has the ability to dissolve in water

define: brachycardia
pulse at rest under 60 bpm
Name the term: episodes of ischemia with pallor and numbness in fingers and toes caused by a temporary constriction of arterioles in the skin
Raynaud disease
cell division
the ability of organisms to reproduce, the continuity of life depends on this reproduction of cells. This cell division occurs as part of the cell cycle.

Trade-Offs
A Constraint on an adaptation is a trade-off, which may involve expenditures of time or energy.A trade-off is an inescapable compromise between traits.
Which is safer to use in a ballon
Helium
activation energy
minimum amount of energy required to convert a normal stable molecule into a reactive molecule

Which of the following is produced in photosynthesis and consumed in respiration? A. carbon dioxide B. glucose C. sunlight D. all of the above
B. glucose
Sex-linked traits
carried on the X and Y chromosomes, and therefore tend to be inherited by one sex more than the other
Fish gills
Fish gills are ventilated by a current of water that enters the mouth, passes through slits in the pharynx, flows over the gills, and then exits the body. Most fishes must expend considerable energy in ventilating their gills because water is dense.
Disputive Selection
a type of natural selection in which both extreme phenotypes are favored over the average phenotype.
Current data suggests that 2 in 3 American is either ____ or _____.
obese, overweight
series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
food chain
natural selection
process by which life forms who adapt to their environment with traits tend to survive and reproduce
Founder Effect
Type of genetic drift in which only a fraction of the total genetic diversity of the original gene pool is represented as a result of a few individuals founding a colony 
What is the net production of ATP in the electron transport chain?

what is relative frequency?
the number of times that an allele occurs in a gene pool compared with the number of times other alleles occur
What is the nose piece?
The objective lenses are mounted to this part.
Currently, scientists are identifying proteins that use ATP as an energy source by
determining if the protein has a known ATP binding site.
