ANSWER:
I think it's the second one.
EXPLANATION:
in primary succession newly exposed or newly formed rock is colonized by living things for the first time. in secondary succession an area that was previously occupied by living things is disturbed, then recolonizeed following the disturbance.
Light excites the electron in the electron transport train and once it goes down the train water replaces the missing electron. the electron transport chain brings it down, hydrogen gets pumped across then when it slides back down the other side, energy is created. chlorophyll is the goo stuff that lets it absorb the light. carbon dioxide goes into the calvin cycle and it rearranged uses energy from the first part. the products of this part is sugar (C6H12O6) and oxygen.
water and carbon dioxide go in, oxygen and sugar come out
Answer:
a. Reduced siRNA-mediated mRNA degradation
Explanation:
The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.
