Researchers can genetically select lettuce crops to cultivate plants that are pest-resistant. One of the concerns of genetically

selected crops is that some traits such as tough leaves for pest resistance may affect a suitable taste and texture desired by humans for eating. What question could be asked to begin this investigation by looking at a measurable dependent variable?
What is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by humans?

What is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants?

What is the effect of crop selection for pest resistance on the sale of green salad in grocery stores?

What is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by grasshoppers?

What type of human activities cause the elevation of atmospheric greenhouse gases
Leto [7]
The amount of greenhouse effect on Earth is directly proportional to the concentration of greenhouse gases in the atmosphere. In this era of industrialization, although it may seem that it has greatly improved the global economy, it also downplays the importance of consistently upholding our role as a steward to Earth. 

The most common types of human activities that continuously worsen the greenhouse effect are: burning of fossil fuels, agriculture, and industrial processes.

The burning of fossil fuels such as coal, oil, and gas emits carbon dioxide which accounts for approximately three-quarters of the warming impact caused by the greenhouse gas emissions. This is amplified significantly through deforestation. 

Methane, which accounts for 14 percent, and nitrous oxide, which accounts for eight percent are one of the major greenhouse gas emissions on earth. This can be sourced out from livestock and rice fields and also fossil fuel extraction and organic waste decay in landfill sites.

Industrial processes would incept fluorinated gases which accounts for one percent of the warming effect of current human greenhouse gas emissions.

Although it may seem that the values are not that high, but it must also be taken into consideration the several or a superfluous number of industries all around the world that simultaneously worsens the already groveling site of the continuously deteriorating and exploited planet Earth.
