Which iof ithe ifollowing iis ia icharacteristic iof ithe ihuman iorganism?
A. iAutotrophic iwith ia igenome istored iin iDNA
B. iHeterotrophic iwith ia igenome istored iin iDNA
C. iAutotrophic iwith ia igenome istored iin iDNA
D.Heterotrophic iwith ia igenome istored iin iRNA
i- iCorrect iAnswer-B.Heterotrophic iwith ia igenome istored iin iDNA
Humans iconsume irather ithan imanufacture inutrient imolecules i(heterotrophic), iand
ihuman igenes iare iencoded iin iDNA
Which iof ithe ifollowing icell itypes iis iresponsible ifor ithe iproduction iof isoluble
iantibodies?
A. iCytotoxic iT-Cell
B. imacrophage iCell
C. iHelper iT-cell
D. iB-Cell
i- iCorrect iAnswer-D. iB-cell
The iproduction iof iantibodies iby iB-cells iis ipart iof ithe ihumoral iresponse ito iantigens.
Cytotoxic iT-cells idestroy ipathogens iand iinfected icells.
Macropahges iingest iand idigest iboth inon-self iand idead icells.
Helper iT-clls ihelp icytotoxic iT-cells iand iother iimmune icells.
A iperson iis isuddenly ifrightened. iWhich iof ithe ifollowing ireactions ioccurs inext?
A. iliver icells iabsorb iglucose ifrom ithe iblood istream.
B. iBlood ivessel isupplying iskeletal imuscles iconstrict.
C. iBlood iVessels isupplying ithe iintestines idilate.
D. iLiver icells irelease iglucose iinto ithe iblood istream.
i- iCorrect iAnswer-D. iLiver icells irelease iglucose iinto ithe iblood istream.
, Epinephrine icauses iliver icells ito ibreak idown iglycogen, iwhich icauses ian iincrease iin
isugar iin ithe iblood istream.
Unlike iskeletal imuscle, icardiac imuscle iis ihighly iresistant ito ilactate-mediated ifatigue
ibecause icardiac imuscle:
A. iuses iaerobic irespiration iin imitochondria ifor ienergy
B. ioperates iwith ielectrical ienergy isupplied iby ithe isinoatrial i(SA) inode
C. iprimarily imetabolizes iglucose iusing ithe ifermentation ipathway
D. idoes inot ineed ioxygen ifor ithe iproduction iof ienergy
i- iCorrect iAnswer-A. iuses iaerobic irespiration iin imitochondria ifor ienergy
Aerobic irespiration i(oxidative irespiration) iis ialmost iexclusively iused iby ithe iheart. iThe
ibyproducts iof ithis itype iof irespiration iare iwater iand icarbon idioxide, inot ilactate. i
The iSA inode, ialso iknown ias ithe ipacemaker, iproduces ielectrical iimpulses ifor iheart
icontraction. i
The ilactose-producing ifermentation ipathway ioperates iduring ioxygen ideprivation iin ithe
iskeletal imuscle.
The iheart iis ihighly isensitive ito ioxygen ideprivation, iand irequires ia isteady ioxygen
isupply ifor iATP iproduction iby ioxidative iphosphorylation iduring iaerobic irespiration.
Ca+H2SO4
Which iof ithe ifollowing istatements icorrectly idescribes ithe iproduct iof ithe ireaction
iabove?
A. iCalcium isulfate
B. iHydrogen isulfide
C. iCalcium isulfide
D. iHydrogen isulfate
i- iCorrect iAnswer-A. icalcium iSulfate
Calcium iand isulfuric iacid ireact ito iproduce icalcium isulfate iand ihydrogen igas
On ian iimaginary iplanet icalled iAlpha iVega, ipurple ieyes i(F) iare idominant iover ipink
ieyes i(f). iWhich ione iof ithe ifollowing icombinations iwill iproduce ionly ioffspring iwith
ipink ieyes?
