ATI TEAS PRACTICE Test for 2024-2025
The iprice iof ia i20" itelevision ichanged ifrom i$450 ito i$400. iFind ithe ipercentage
ichange iin iprice.
A.
-10%
B.
-11%
C.
-13%
D.
-15% iCorrect ianswer: i-11%
Change iin iprice: i450 i- i400 i= i50
To idetermine ithe ipercentage ichange, idivide ithe ichange iin iprice iby ithe iinitial
iprice:
50 i= i0.1111
450
Multiply iby i100 ito idetermine ithe ipercentage: i0.1111 i× i100 i= i11.11%
Because ithe iprice idecreased, ithe ichange iin iprice iis inegative: i-11.11%, ior
iabout i-11%
,Which iof ithe ifollowing iis inot ia itype iof inatural ilipid?
A.
Supersaturated
B.
Polyunsaturated
C.
Saturated
D.
Unsaturated iCorrect ianswer: iSupersaturated
There iare ithree itypes iof inatural ilipids: iunsaturated, ipolyunsaturated, iand
isaturated. iSupersaturation iis ia inot ia inaturally ioccurring ilipid.
Unsaturated iand ipolyunsaturated ilipids ihave ione ior imore idouble ibonds
ibetween icarbon iatoms iof ifatty iacid ichains; isaturated ilipids ishare ino isuch
idouble ibonds.
A icommon iexample iof isupersaturation iis irock icandy, iwhich iis icreated ifrom ia
isupersaturated isugar isolution.
Which iof ithe ifollowing iis inot itrue iof imitosis?
A.
Daughter icells iare idifferent ithan iparent icells
, B.
Daughter icells iare iidentical ito iparent icells
C.
It iproduces idaughter icells
D.
It ioccurs ionly iin ieukaryotic icells iCorrect ianswer: iDaughter icells iare idifferent
ithan iparent icells
Mitosis iis ia icell icycle iduring iwhich ia iparent icell iproduces ian iidentical
idaughter icell. iIt ihas ifour imain iphases: iprophase, imetaphase, ianaphase, iand
itelophase. iSince ithe iparent iand idaughter icells iare iidentical, iboth idiploids iand
ihaploids ican iundergo imitosis.
Mitosis iis ia ifour-stage iprocess ithat icreates itwo iidentical icells ifrom ione
ioriginal icell.
Prophase iis ithe ifirst iand ilongest istage iof imitosis. iIn ithis istage, ithe
ichromosomes ibecome ivisible iand ithe icentrioles iseparate iand imove ito
iopposite ipoles iof ithe icell.
Metaphase iis ithe isecond istage iof imitosis. iIn ithis istage, ithe ichromosomes iline
iup iacross ithe icenter iof ithe icell iand ibecome iconnected ito ithe ispindle ifiber iat
itheir icentromere.
Anaphase iis ithe ithird istage iof imitosis. iIn ithis istage, ithe isister ichromatids
iseparate iinto iindividual ichromosomes iand iare ipulled iapart.
Telophase iis ithe ifourth iand ilast istage iof imitosis. iDuring ithis istage, ithe
ichromosomes igather iat iopposite iends iof ithe icell iand ilose itheir idistinct irod-
like ishapes. iTwo inew inuclear imembranes ithen iform iaround ieach iof ithe itwo
iregions iof iDNA iand ithe ispindle ifibers idisappear.
What iis ithe irole iof ithe iGolgi iapparatus iin ithe icell?
The iprice iof ia i20" itelevision ichanged ifrom i$450 ito i$400. iFind ithe ipercentage
