Removing vegetation and soil, grading the land surface, and constructing drainage networks increase runoff to steams from rainfall and snowmelt. As a result, the peak discharge, volume, and frequency of floods increase in nearby streams. Changes to steam channels during urban development can limit their capacity to convey floodwaters. Roads and buildings constructed in flood-prone areas are exposed to increased flood hazards, in clouding inundation and erosion, as new development continues.

The researchers introduced a small RNA complementary to a portion of the mRNA encoding protein A into the Brec-MUT cells growing
Sonbull [250]

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.

If a pea plant that is herterozygous for rounds, yellow peas is crossed with a pea plant that is homozygous for round peas but h
Keith_Richards [23]

Answer: There re two different types of phenotypes in the offsprings that is Round yellow and Round green.

Explanation-

As per the Mendelian inheritance, Round shape and yellow color of pea are dominant over wrinkled shape and green color of pea.

According to the question, genotypes of parents are- RrYy ( heterzygous for round and yellow) and RRYy ( homozygous for round and heterozygous for yellow).

The first parent can produce four different gametes that is RY, Ry, rY, ry whereas the second parent will produce only two types of gametes that is RY and Ry.

When they are crossed, they will produce two different phenotypes in the offsprings.
