Which testing method is considered better than traditional chemical analysis testing?
methods of analyzing trace evidence are more accurate, faster, and can be automated. These include mass spectroscopy, infrared spectroscopy, and gas-liquid chromatography.
The Trace Materials Unit uses methods and techniques to predict items of evidence. Instrumental methods are considered faster in providing results as compared to traditional chemical analysis.
What is the Instrumental method?Instrumental analysis is a field of analytical chemistry that helps to investigate analytes using some sort of scientific instrument.
Many of the instrumental methods can be done for both qualitative and quantitative analysis.
The major categories of instrumental methods are as follows:
Spectral. Electroanalytical. Separatory.Instrumental methods are considered much faster at producing results as compared to traditional chemical analysis. This factor is often important during a crime investigation.
Thus, the instrumental method is considered better as compared to chemical analysis.

Charles Darwin’s theory of evolution states that evolution occurs by natural selection. Individuals in a species shows variation in physical characteristics. This variation is because of the differences in their genes.
What is evolution?Evolution is the process by which species adapt over time in response to their changing environment.
Individuals with characteristics best match to their environment are more likely to survive, finding food, avoiding predators and resisting disease. These individuals are more likely to reproduce and pass their genes on to their children.

PLEASE HELP ME FAST. How would a reduction of carbon dioxide emissions affect the oceans? Select the two correct answers.
It would reduce ocean temperatures.
It would increase ocean temperatures.
It would lower the pH of the oceans.
It would raise the pH of the oceans.
Answer:
It would lower the pH of the oceans.
Explanation:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact.
CO2 emissions are also making the ocean more acidic, making many marine species and ecosystems increasingly vulnerable. Ocean acidification reduces the ability of marine organisms, such as corals, plankton and shellfish, to build their shells and skeletal structures.

The plants in this ecosystem are dark in color to absorb sunlight, covered in hair and grow in clumps. What type of ecosystem could a plant with these
adaptations be best fit for?
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.
What is tundra ecosystem?Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.
Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.

The plant tissue that is pointed out by the lines in the enlarged diagram is ground tissue. Therefore, option B is correct.
What are ground tissues?Ground tissues are one of the three types of plant tissues. The other two tissues are dermal and vascular tissues. Ground tissues are responsible for most of the metabolic functions of the plant, including photosynthesis, storage, and support.
Ground tissues are composed of several different types of cells: parenchyma, collenchyma, and sclerenchyma. Parenchyma cells are the most common type of ground tissue cells. They are responsible for photosynthesis, storage, and gas exchange.
Collenchyma cells provide support to growing parts of the plant. Sclerenchyma cells provide structural support to mature parts of the plant. Thus, option B is correct.
