DECK 1

Question 1

sodium pump most active in cells of

Answer 1

loop of henle

Question 2

gastric cancer will results if genetic mutations happen (bacterial infection)

Answer 2

mutations in proliferating somatic cells - gastric as with mucosal cells in stomach

Question 3

in hyperglyceima what in response

Answer 3

insulin secretion

Question 4

___ has to be distributed throughout the body for necessary osmosis, and dehydration to occur

Answer 4

glucose

Question 5

You can simplify it by thinking in terms of the equation osmotic pressure= iMRT. Therefore, the only thing you have to focus on is solute concentration (M). Since in this case, the excess unabsorbed fats increases solute concentration, osmotic pressure increases.

Question 6

expect to find ice in the ECF examples

Answer 6

blood plasma, lymph NOT CYTOPLASM

Question 7

if it asks when relying on anerobic resp based on heart rate what is it

Answer 7

HR is zero

Question 8

inflation on lungs, inspiration, causes what to diaphram and the muscles? also is it neg or pos intrapleural pressure

Answer 8

dia contract, muscles expand, negtaive - boyle law

Question 9

if it says genes for rRNA located extrachromosomally means

Answer 9

self replicating, must do just as chromosomes do if they are passed from on gen to the next

Question 10

if extra S phase will happen triggered by

Answer 10

low concentrations of DNA in the macronucleus

Question 11

binary fission leads to

Answer 11

uneven distribution of chromosomes and uneven distribution of alleles pass

Question 12

meiosis produces cells that are genetically unique from the parent and contain only half as much DNA.

Question 13

template strand is the

Answer 13

antisense strand

Question 14

order of embryo

Answer 14

Zygote –> Morula –> Blastula –> Gastrula –> Embryo.

Question 15

if mrna was not degraded rapidly by intracell agents then which processes would be most affected

Answer 15

coordination of cell differentiation

Question 16

if someone was so excited caused her urine more this bc of

Answer 16

inc in bp, caused by excitement or anx

Question 17

which binds oxygen tighter

Answer 17

myoglobin in muscle and organs

Question 18

what control heart rate

Answer 18

brain stem

Question 19

what control motor coordination

Answer 19

cerebellum

Question 20

what control the appetitie

Answer 20

hypothalamus

Question 21

if one would randomly vasodialte blod vessel after being in the cold where used to conserve what would be reason

Answer 21

maintain sufficient oxygen to cells

Question 22

if we want to modify the reflex arc thing for feeling pain we add neurons where

Answer 22

internurons or synpase sites - not at the painful stimuls and NOT at the muscle itself - for pain recognized need path travel up to the CNS

Question 23

ribosomes are found

Answer 23

both prok and euk

Question 24

euk cells only have

Answer 24

mitochondria - membrane bound, prok NOT

Question 25

how does fungi produce

Answer 25

asexually

Question 26

synpasis is the pairing of ______ and binding togther

Answer 26

homolog chromo only meiosis 1

Question 27

splitting of centromeres specifc to

Answer 27

mitosis

Question 28

inbreeding can reduce the fitness of population in short term bc in increases the

Answer 28

incidence of expression of deleterious recessive traits

Question 29

lower than normal bp correlated with dec rate of urine output

Answer 29

so more absorption - There is less blood flow for filtration when blood pressure is low

Question 30

increased blood pressure means

Answer 30

inc urinary output

Question 31

increased glomelaur fultration rate means

Answer 31

inc filtration rate means less time to absorb water and this more water leaves the body through urine

Question 32

cardiac output formula

Answer 32

SV times HR

Question 33

main factors to determine BP

Answer 33

cardiac output and the resistance to blood flow

Question 34

during hemorrahe waht do blood vessels do

Answer 34

contrcti

Question 35

angitension 2 causes blood vessels to

Answer 35

constrict - inc bp

Question 36

liver can partially regenerate folllowing illness/damage so how does it do this

Answer 36

mitosis

Question 37

most bacterial cells and human cells are alike in that

Answer 37

we both can produce ATP via ATP synthase

Question 38

reduced vit D activity will cause

Answer 38

reduce absorb ingested calcium levels in the blood

Question 39

PTH and calcium

Answer 39

promote breakdown of calcium - more in the blood floating

Question 40

: Vitamin D aids in calcium absorption in the small intestine. -

Answer 40

Vitamin D will stimulate both osteoclast and osteoblast activity, and therefore increase bone turnover. * increase absorption of calcium and phosphate from the gut - does both still (absorb and break)

Question 41

when already have high calcium levels then we dont need Vitamin D

Answer 41

When vitamin D level is low, the absorption of calcium in the intestines becomes less, which then causes the level of calcium in the blood to go down. As a consequence the parathyroid glands become more active and produce more PTH that causes calcium to come out of the bones, therefore weakening the bones.

Question 42

where is calcitonin released from

Answer 42

thyroid gland

Question 43

natural selection assocaited with

Answer 43

evolve where individual have UV reflective dewlaps produces more offspring than did ppl without them

Question 44

decrease in blood volume means dec in bp too
