sasho [114]

<h2>Howdy, </h2>

FiRsT PaRt of The QuEsTiOn:

The Risks of Modern agricultural practices are-
contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.

The benefits of Modern Agricultural practices are-
An increase in yield of primary crops and lower food prices is as the result of modern technology like new crop varieties, the use of big data and precision agriculture.

Modern machinery like tractors and threshers when used up in farming make ploughing and harvesting faster.

SeCoNd PaRt Of ThE QuEsTioN:

No, I don't think the Benefits outweigh the RISKS of hurting the nature because we are compromising the needs of the future for more yield of crops. Modern practices may give you faster results but it takes away the fertility of the soil instead, It makes the land infertile. After using these modern practices you may not even have the land to do agriculture with.

Why do phospholipids tend to spontaneously orient themselves into something resembling a membrane such as the lipid-bilayer sphe
KatRina [158]

The phospholipid bilayer functions mainly as a structural framework for the membrane where the polar heads of the phospholipids tend to orient towards their polar surroundings, preserving the hydrophobic part from any contact with water.

<h3>What are phospholipids?</h3>

They are lipid molecules that have a strongly polar group in addition to the hydrophobic hydrocarbon chain.

<h3>Characteristics of phospholipids</h3>

  • The polar heads are oriented towards the aqueous medium (intra and extracellular).

  • The hydrophobic tails tend to be oriented towards the lipid medium, that is, inside the bilayer, constituting the membrane matrix.

Therefore, we can conclude that phospholipids, due to their amphipathic nature, tend to orient or organize themselves spontaneously, forming the so-called lipid bilayer.
