It’s true (a) because bones become brittle and easier to break if theyre not used. bones more frequently used become stronger.
It is controlled by negative feedback loop.Let's say you have high glucose level in your blood,that will be registered and pancreas will produce more insulin to keep it in the normal range.Therefore by negative feedback loop it will regulate homeostasis
Answer:
D. MicroRNA-1/206 targets c-Met mRNA for destruction via RISC.
Explanation:
microRNA's are non-coding RNA's, that is, they are not translated to proteins. MicroRNA-1/206 leads to gene silencing by 'tagging' the c-Met mRNA for cleavage by RISC proteins.
RISC: RNA-induced silencing complex is a ribonucleoprotein complex that leads to the incorporation of a single strand of micro RNA (or siRNA) that will bind to the targeted mRNA. The microRNA or siRNA strand will tag the targeted RNA for cleavage by proteins from the ribonucleoprotein. No translation will occur.
It destroy's their habitats and other resources they need to survive. <span />
I think water is indeed an inexhaustible resource. We can keep using it, but it will always come back as rain, snow, ice etc. Water energy sources are one of the biggest renewable energy sources in the world.
