is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?

Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger

Answers

Answer 1

Answer:

c-risk trigger

Explanation:

The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA.  The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation.  As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.

Is GMO is good or bad? And why? Can you please explain to me your answer so that i can understand, thanks!

Answers

Answer:

There is no data to indicate that consumption of GMOs is bad for human health. ... In addition, over the two decades that GMOs have been on the market, there have been no occurrences of health issues due to genetically modified organism

Explanation:

but its your own opinion

Answer: GMOs are generally though of as bad

Explanation: GMO stands for Genetically Modified Organism.

People take genes from one plant, lets say from a plant that can withstand cold temperatures, and puts it into another plant. This can give the gene of withstanding cold temperatures to the new plant.

A long time ago people would breed plants until they got traits that they like. This takes a very long time. Now with GMOs, you can get the traits you want much faster.

People are concerned with GMOs for allergies, cancer, and environmental harm. Current research hasn't outlined too many risks of GMOs yet as long-term research is still needed.

Answer:

At land

Explanation:

Carbon is a raw material for photosynthesis, in the form of carbon dioxide. Green plants use it to make vital organic compounds. On the land, plants get the carbon they need as a gas from the air. In water, plants ranging from seaweeds to phytoplankton are supplied by dissolved carbon dioxide, CO2.

You've been tasked to study the movements of condensed chromosomes during cell division.
You have access to a magnifying glass, a standard light microscope, a scanning electron
microscope and a transmission electron microscope. Which piece of equipment would you choose
and why? Also why would you NOT choose the others? (max 50 words)

Answers

In order to see something as small as a chromosome, It is necessary to employ the use of a scanning electron microscope.

The question states that we wish to study the movements of condensed chromosomes during cellular division. This means that we will need a scope capable of not only looking inside of a cell but even inside of the nucleus of a cell, an extremely minute space.

Logically, a magnifying glass will not be able to accomplish this given that it only allows us to see macroscopic elements, many hundreds of times bigger than what we wish to observe. We run into similar limitations with standard light and transmission microscopes. Although these allow us to see things on a microscopic level, they fall short of the desired capability.

Though the transmission microscope can see even smaller elements than a standard light microscope, both are limited to the surface of cells. The SEM or scanning electron microscope, on the other hand, allows the user to see elements down to 0.1 nanometers in size. Given that chromosomes are between 10 and 30 nanometers in size, we can use this microscope for the desired study.

Describe the elements and compounds of coal being mined

Answers

Answer:

The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements

Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.

Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.

Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.
