Answer:
The best explanation for why tiny river has recently been experiencing increasing erosion of the sediment along its banks is increased runoff.
Explanation:
The main agents of soil erosion are wind, climate change, ice and water circulation.
Runoff is caused by precipitation, which is capable of produce erosion on the banks of a river, with some negative consequences for the environment.
Runoff depends on the flow of water, coming from rainfall, which moves across the surface of the soil, with great capacity for infiltration and erosion. In this case, runoff is the only possible cause of soil erosion
With respect to the other options:
<em>Decreased Slope
, decreased rainfall and increased vegetation are not factors related to the erosion in the bank of a river. </em>
ENSO phenomenon causes significan climate global changes, affecting especially the Southern Hemisphere. In south Asia regions, such as Philippines, the weather becomes cooler, drier than normal.
-----------------------------------
The El Nino Southern Oscillation -<em>ENSO</em>- phenomenon produces due to a complex system of climatic oscillations between the ocean and the atmosphere.
This phenomenon causes significant perturbations in the usual pluvial regimens in the tropics. It provokes
- dry seasons in areas where it usually rains
- rainy seasons in desertic regions.
ENSO phenomenon is dominant in the global climate system.
SOUTHERN HEMISPHERE
⇒ <u><em>Under normal conditions</em></u>
- Pacific warm water and air masses move westward, making it possible for cold water to ascend in South America´s coasts, in a process known as upwelling.
- Upwelling occurs in South America, providing nutrients from the bottom to the animals, especially fishes -which favors fisheries activities-.
- Humidity goes straight to the west precipitating in Eastsouth Asia, Australia, and New Zealand, among other places.
⇒ <u><em>Under El Niño conditions</em></u>
- A tropical and weak stream in the Pacific acquires strength while the opposite streams debilitate.
- This change impedes warm water go eastward, remaining on South America´s coasts.
- <em>Upwelling does not occur on the South America coasts</em>. In some regions, temperatures rise, and unusual precipitations occur in desertic or dry areas -<em>Atacama desert</em>-.
- Other affected areas are <em>Eastsouth Asia, Australia, and New Zealand</em>, where there are fewer precipitations and cooler temperatures. <em>Rainfall drops below the average</em>, affecting crops and livestock.
Among the affected areas in the Eastsouth Asia, we can mension the Philippines. Their economic activities are particularly affected during ENSO events.
NOTHERN HEMISPHERE
ENSO also provokes changes in general extratropical circulation, contributing to some abnormal situations in the northern hemisphere weather during winter, including severe precipitations and cooler temperatures in the southeast USA, north of Mexico, Gulf of Mexico, Strait of Florida, and western Cuba.

Answer: Option A
Explanation:
Before the mRNA which has been processed from DNA is taken and transported to the ribosomes in the cytoplasm for the translation process, some modifications are made to the mRNA before transport. This includes
1. Capping: addition of 5'-5' phosphate bonds to the 5' terminus of the mRNA. Forms the cap structure that is essentials for binding to ribosomes via special proteins attached to the cap structure
2. Addition of poly(A) tail: a poly(A) addition signal (AAUAAA) is attached to the 3' terminus of the mRNA. They are important in translation initiation and degradation prevention
3. Splicing: this is likely the most remarkable processing in eukaryotes. It involves the removal of intron regions by excision from the present-mRNA and then ligating the exon regions together giving rise to the mRNA.
