How would the soil biota be afected by using traditional chemical pesticides and would this difer from using transgenic methods

Answer:

The impact of pesticides on soil biota can be either positive or negative, depending on the type of pesticide used. Genetically modified organisms (GMOs) are generally designed in order to be more resistant to pesticides, thereby GMOs might have a higher impact on the soil biota (however, the evidence is not conclusive and case by case should be evaluated)

Explanation:

Traditional chemical pesticides are chemical substances used to control pests (e.g., insect pests affecting corn yield). Examples of traditional chemical pesticides include 2,4-Dichlorophenoxyacetic Acid, DDT, Atrazine, Chlordecone, etc. The impacts of these traditional pesticides on soil biota are variable according to the type of product used, the rate at which these products are applied, the target/non-target soil biota (e.g., bacteria, algae, fungi, protozoa, insects, nematodes). For example, it has been reported long-term contamination of DDT on soil microflora (i.e., microalgae and cyanobacteria), thereby these non-target species declined with increasing DDT use; however, direct effects on fungi populations were not observed. Genetically modified organisms (GMOs) are organisms whose DNA has been engineered by using molecular biology techniques. In crop improvement, GMO plants are designed to be more resistant to chemical pesticides and also to produce pesticides themselves, for example, Bt crops that produce a toxin from Bacillus thuringiensis (Bt) that can kill insect pests. GMO plants can also be designed to be more resistant to pesticides, thereby affecting soil biota at higher scale values. Nonetheless, it is important to highlight that like chemical pesticides, the effects of GMOs on soil biota are also variable depending on the type of GMO, which pesticide GMO is producing, target/non-target soil species, etc.

Which two structures are found at the outside of the cell?

It was the big day; Lance had been training for months in anticipation of the annual “Dasher Twenty-Six-Two.” As he laced up his sneakers, he thought back to the endless grind of aerobic training he had accomplished. Hour after hour of lung-burning, quad frying jogging on pavement and dirty. He was ready mentally and physically, plus he had a secret weapon ready to go. Lance had been experimenting in the use of a thick, sugar saturated gel-nutrition to supplement his running. He anticipated finishing just before the three-hour mark and he planned to eat his special goo around hour two for a much-needed energy boost. The goo solution was a mixture of maltose, sucrose, and glucose, as well as some salt. Water would be available on the course every few miles and with his nutrition plan set he found his way to the line. *BOOM*

The start gun leaked smoke as wave after wave of runner set off. Miles started flowing by… five miles feeling good… Mile thirteen halfway there! Just as the two-hour mark was upon him, Lance pulled the gel from his pocket and slurped the gooey syrup down. Mile fifteen Phew, heavy legs… Mile eighteen Legs are burning but I got it… then came a hit of fatigue.

He had read about this before. The dreaded bonk. Bonking was said to be the final drips of glycogen being removed from the muscle’s cells, with an accompanying burn suggesting rapid production of lactate. It also meant he had spent the last two hours less aerobic than he thought. Making it to mile twenty-two, Lance noticed his heart rate ten-beats over his planned pace. His breath was getting harsher, his legs getting weaker. The mile twenty-four marker went by and he was down to nearly a walk, lips dry and stomach lurching. The last half mile was a blur as Lance crossed the line his raised arms quickly fell, and so did he, right into a chair near the finish line.

Discuss the necessity of Lance’s training to prepare for his ability to fuel a marathon with specific reference to the major organ systems involved and their purpose. Identify the needed reactants and excreted products Lance utilized during his ongoing respiring, with specific reference to where each is created or used. Finally, predict the influence of his experimental goo and suggest advantages and disadvantages to its use, as well as better use with reference to time and impact on the ability to enter and circulate to where it would be needed

Which of these is the best explanation for why the rock on the ocean floor and the rock on the continent are
NOT the same age?
There has been a lot of erosion on the continent and the older rock has been washed away.
There has been a lot of erosion on the ocean floor and the older rock has washed away.
Due to the movement of the plates, the rocks that make up the ocean floor are pulled inside the earth
more often and are much younger.
