What is agricultural monoculture and why is that bad for crops?

Katarina [22]

<h2>EXPLANATION:</h2>

<h3>Modern monoculture requires vast amounts of rain for irrigating crops as moisture retention is limited in the soil. A lack of topsoil also increases rain runoff. To achieve this vast amount of extra water it means draining from lakes, rivers, and reservoirs, which is exhausting natural resources and aquatic ecosystems.</h3>

When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.

When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.

When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.

All of these observations indicated the presence of covalent bonds.

Pol determined that the pH of the sample is 7, which shows the sample is neutral.

Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.

The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
Active transportation comes in two flavors:

Primary active transport
Secondary active transport.
