Answer:
Delivered small RNAs can inhibit protein A production through the RNA interference (RNAi) mechanism, and thus impairs angiogenesis
Explanation:
The pregnancy-associated plasma protein-A is a protease enzyme involved in the formation of new blood vessels by increasing insulin-like growth factor I (IGF-I) bioavailability. Moreover, small RNAs (<200 nucleotides in length, generally 18 to 30 nucleotides) are non-coding RNA molecules that function in RNA silencing through the RNA interference (RNAi) pathway. Small RNAs are widely used in molecular biology laboratories because they can be delivered into specific cells in order to silence target mRNAs such as, in this case, the mRNA encoding protein A, by complementary base pairing and thereby inducing translational repression. In consequence, mRNAs complementary to delivered small RNAs are silenced through RNAi pathways, i.e., by cleavage of the target mRNA and/or mRNA destabilization.
Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
<h3>What is humidity?</h3>
Humidity is used to determine the concentration of water vapour that is available in the air.
when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.
Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
