Answer from: ReaLily

Answer is preserve

1. Removing oxygen: The removal of oxygen from food preserves the food by avoiding the oxidation of food that leads to spoilage.Cover the food or vegetable tightly in air tight container to avoid oxygen reaching the cut cells which will cause spoilage of food.The fruits and vegetables should immediately be boiled or cooked to prevent oxidation.

2. Removing moisture: The removal of excess water from vegetables and fruits helps in preservation of food. The bacterial growth that spoils the food grows in moist environment hence reducing the moisture content will preserve food.

3. Killing spoilage organism: The ultraviolet light and infrared light are used to kill the organisms causing spoilage of food. Flash technique is also used for preserving food from microorganism.

Answer from: Quest

increase soil erosion reduce soil erosion

cattle grazing hydroseeding

deforestation contour plowing

planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

Answer from: Quest

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

Mike was adopted, and his biological family history is unknown. although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. mike has heard about commercial laboratories that can compare segments of your dna to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. the results of these types of tests are highly inconclusive. if mike's dna showed that he shares similarities in a segment of dna with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. these tests can cost more than $2,500 and are not covered by many insurance companies. do you think that mike should undergo the genetic tests? explain your answer. what are the potential pros and cons of having such tests done? describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations.
