| what affect does testoterone have on song birds? |
|
Definition
active song-regions in brain that
affect singing behavior are
greatly expanded due to
testosterone production in
the spring |
|
|
Term
| how is fitness and singing related in song birds |
|
Definition
| males with highest fitness can sing the best, directly related to genetics |
|
|
Term
| describe E.O. Wilson's theory of sociobilogy |
|
Definition
| social behaviors have rigid genetic controls, behavior is like an organ, should consider biology before pyschology, sociology, theology (all depend on conciousness) |
|
|
Term
| how would sociobiology be weakened? |
|
Definition
| if social interactions are not due to genetics |
|
|
Term

|
|
Term
| what are two possible explanations of sociality? |
|
Definition
| genetic chromosomal factors, predation factors |
|
|
Term
| what could be one impotus for social behavior |
|
Definition
| if males resulted from unfertalized eggs and females resulted from fertilized eggs |
|
|
Term
| what affects did human child birth have on sociology? |
|
Definition
| it gave males an interest in helping for child care; for successful reproduction energy must be put into family care |
|
|
Term
| wat does alitricial imply |
|
Definition
| offspring require long periods of care |
|
|
Term
| what is the primary means for transmitting culture in humans and what is it linked to |
|
Definition
| language; linked to brain size |
|
|
Term
| what causes the large size of the human head? |
|
Definition
| the growth of the cerebreal cortex |
|
|
Term
|
Definition
| a highly folded, greatly expanded portion of the forebrain. It is the center for higher reasoning ability and language; a mass of neural cells |
|
|
Term
|
Definition
predictably disproportionate change
in one measurement (say, brain
weight) with respect to another (say,
body weight), in ontogeny or
phylogeny |
|
|
Term
| what happens in embryo development in terms of neural cells and dhnc |
|
Definition
| neural cells amass near the dhnc |
|
|
Term
| what rate do the neural cells amass at during embryo development? |
|
Definition
|
|
Term
| what happens in humans embryos after 50 days? |
|
Definition
cells migrate from the ventricular
surface to the developing cortex. Cortical cells do not undergo mitosis
any longer due to genetic switch |
|
|
Term
| what affect can a short time have on stem cell mitosis? |
|
Definition
| only slightly longer period can result in many more neural cells |
|
|
Term
A mutation in a single gene
causes |
|
Definition
a reduction in the time
that stem cells are produced |
|
|
Term
| The development of the cortex is produced by |
|
Definition
tool-kit genes that are
also found in other members of the Animalia. Manipulation of the tool-
kit might produce cures to genetic diseases such as microcephaly |
|
|
Term
| how many base pairs long is the human genome |
|
Definition
|
|
Term
| how many genes in human genome? |
|
Definition
|
|
Term
| how many base pairs per gene in human genome? |
|
Definition
|
|
Term
| how much of the genome shows base pair polymorphism |
|
Definition
|
|
Term
| what is interesting about the length of the genome in organisms such as amoebas? |
|
Definition
| much longer than humans (290 bbp) |
|
|
Term
| how is the human proteome in relation to the genome (lenghth wise) |
|
Definition
proteome significantly larger than our
genome |
|
|
Term
|
Definition
a protein that facilitates
chemical reactions. |
|
|
Term
| what are drugs in terms of enzymes? |
|
Definition
they are molecules that
can block the active sites of
enzymes |
|
|
Term
|
Definition
a proteobacterium
that readily infects plant tissue, and
lives inside the plant |
|
|
Term
|
Definition
extra-chromosomal DNA
rings that are transcribed and translated
into proteins |
|
|
Term
| how are plasmids exchanged |
|
Definition
exchanged by lateral
transfer (aka HGT) and share their
genes with other cell’s chromosomes |
|
|
Term
| what is one possible problem of bacillus toxin? |
|
Definition
it is 80,000
times more toxic than commercial pesticides |
|
