A group of elderly residents were commenting on how many cell functions decline with age. One resident commented that many of hi
s friends who lived under large electromagnetic towers seemed to experience aging at an accelerated rate in comparison with residents who lived nearby in lakefront housing. This observation is the basis for which theory on aging?A) Theories of genetic influencesB) Programmed cell receptor theoriesC) Insufficient telomerase enzyme theoryD) Error theory associated with DNA damage
<em>The correct option is D) Error theory associated with DNA damage</em>
Explanation:
Error theory suggests that aging results from DNA mutation or faulty repair. Another group of theories of aging focuses on programmed cell changes with genetic influences that systematically cause cell senescence. Elimination of receptor sites is not part of aging theory. Telomerase enzyme is thought to reduce the shortening of the chromosomes and loss of telomere DNA with each cell replication.
In general, for most things, A would be correct (Any time of the day). It kind of depends on what you ar collecting the sample for. I think the earlier the better but it doesnt usually matter.
The kidneys maintain our body's water balance by controlling the water concentration of blood plasma. The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine.
