Show also the selenate anion (SeO₄^2- ) could be accumulated by a root cell using a symport, and how the Mn²⁺ ion would be exported from the cell using an antiport by drawing diagrams of both.

Expert Solution

Selenate ions are rapidly absorbed and transported in plant xylem sap. ... Soil and plant management in seleniferous areas must take into account soil types and the genetic tolerance by plants of high selenium and salt concentrations. It absorbed by symport way with the phosphate ions.

Manganese (Mn) is an important micronutrient for plant growth and development and sustains metabolic roles within different plant cell compartments. The metal is an essential cofactor for the oxygen-evolving complex (OEC) of the photosynthetic machinery, catalyzing the water-splitting reaction in photosystem II (PSII). Mn toxicity occurs on poorly drained and acidic soils in which high amounts of Mn are rendered available. Consequently, plants have evolved mechanisms to tightly regulate Mn uptake, trafficking, and storage. Manganese (Mn) export from plant cell through the Ca2+/Cation Antiporter

Uniporters, symporters, and antiporters are proteins that are used in transport of substances across a cell membrane. ... Symporters and antiporters are involved in active transport. Antiporters transport molecules in opposite directions, while symporters transport molecules in the same direction.

We are doing this problem in R software. If you could also show how to do it in that along with the normal work that would be much appreciated. Problem 1 Acid precipitation id linked to the disappearance of sport fish and other organisms from lakes. Sources of air pollution, including automobile emissions and burning fossil fuels, add to the natural acidity of precipitation. The Wisconsin Department of Natural Resources initiated a precipitation monitoring program with the goal of developing...
