Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.
- After death, the stomach contains identifiable ingested foods within two hours.
- Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.
- Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.
- The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).

Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
<span>On the left, they drain into the renal vein
which in turn drains into the inferior vena cava. By contrast, all the
lumbar veins and hepatic veins usually drain directly into the inferior vena cava.</span>
Scientific method includes some steps that are necessary for conducting the successful experiment.
1. Make an observation
You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.
2. Ask a question
How does the light influence plant growth?
Are the wavelengths of the light important?
Is natural light source (sun) better for plant growth...
3. Form a hypothesis - it is a testable potential answer to the question
For example: Sunlight induces higher phototropic reaction.
4. Make a prediction
Sunlight is richer in red and blue hues which are both extremely important to plant growth.
5. Test the prediction
Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.
6. Analyze the data and make a conclusion.
In the us- Anchorage, Alaska because the natural environment is far more resilient to a major weather event than a large city setting and can better adapt to changing sea levels or temperatures. With less people and man-made infrastructure, there are fewer things to be maintained in the area, allowing the wilderness to react naturally to changing weather patterns and climate.
outside the us- Denmark because the country has continued to make strides forward, in air quality in particular. On the previous report, 78.8% of the population was exposed to unsafe levels of fine particle air pollution; now, the figure has dropped to 56.9%. Denmark tops the list of countries doing the most to protect the environment, among them having at least half its energy consumption come from renewables by 2030 and to be independent of fossil fuels by 2050.
