Answer:
Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.
Explanation: Scientists: Botantist, Cytoligist, Agronomist.
Hope this helps!!
Dichotomous keys are used in research to identify organisms like plants, animals, and microorganisms. Botanists, Agronomists, and Cytoligist can use dichotomous keys.
What are dichotomous keys?Dichotomous keys are the identification method of a group of organisms based on the alternative characters and divisions. They identify an organism based on immutable features.
Botanists study plants, Cytoligist study the function and structure of cells, and Agronomists study crop plants and soil. These types of scientists use the key to identify plants and animals.
Therefore, many scientists like Botanists, Agronomists, and Cytoligist use dichotomous keys.

Answer:
In many areas, rain or snowmelt on seasonally frozen soil is the single leading cause of severe runoff and erosion events. As soils freeze, ice blocks the soil pores, greatly diminishing the permeability of the soil. This is aggravated by the tendency of water to migrate to the freezing front, causing elevated ice content and frost heave.

How does burning carbon-containing fuels contribute to Earth’s climate change problem?
The chemical reaction that happens when ethanol and oxygen mix produces two substances: carbon dioxide and water in the gas phase. Since both of these are invisible, colorless gases, it seems like nothing is left of the liquid that was in your gas tank. However, the atoms of the reactants haven’t disappeared at all—they’ve only rearranged to form the products. The carbon dioxide and water produced by this chemical reaction enter the atmosphere whenever we burn ethanol or other carbon-containing fuels. In the recent past, humans have increased the amount of carbon dioxide in Earth’s atmosphere by burning such fuels, resulting in widespread changes to Earth’s climate. In response to these effects, scientists are working to find fuels that can release energy without producing carbon dioxide.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?
Answer:
float
Explanation:
since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float
then 1.9g/ml < 1g/l
Answer:
it would sink
Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that

What is the crest and trough of a wave?
Answer:
Explanation:
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.

Read the article excerpt below then answer the question.
Why is hydrogen a “cleaner” fuel source than gasoline?
Compared to the carbon dioxide that is produced when we burn gasoline, ethanol, and other carbon-containing fuels, the water produced by burning hydrogen has a less harmful effect on Earth’s climate. If we can power our cars with hydrogen without producing carbon dioxide, then why don’t more vehicles use hydrogen fuel? Unfortunately, the technology needed to use hydrogen as a fuel is expensive, and storing hydrogen fuel can be difficult. Also, the most common way of getting pure hydrogen is by separating it from substances that contain carbon—so although burning hydrogen fuel does less harm to Earth’s climate than burning carbon-containing fuels, the production of hydrogen fuel is still a problem for scientists trying to reduce climate change.
Why is hydrogen a “cleaner” fuel source than gasoline?
hydrogen is natural created and in the air already, gas is a fossil fuel and is killing the Ozone layer. carbon dioxide is a poison and can really harm us and the world.

What are some of the reasons climate change is so bad for communities of color? HELP PLSSSSSSSS
Answer:
Here is a link that will explain more specifically.
https://www.greenamerica.org/climate-justice-all/people-color-are-front-lines-climate-crisis
Explanation:
The United Nations International Panel on Climate Change’s (IPCC) 2013 climate change science report states with “90 to 99 percent certainty” that more frequent and more severe weather events like droughts, intense heat waves, and “more frequent/ intense heavy rainfall events” are a consequence of the climate crisis. And it is communities of color that are bearing the brunt of those events, say many experts.
Other communities of color are also feeling the heat. In California, for example, record heat waves and droughts are affecting Latino communities hardest throughout the state, says Mario Santoyo of the California Latino Water Coalition.
As state farmers see their fruit and vegetable crops shrink from lack of water, it’s the state’s majority-Latino farmworkers who are struggling most as a result, as they scramble to get enough hours picking crops to earn a livable wage.

Use the reading below to answer the question.
The layer of soil above the permafrost is too shallow for plants with deep roots to live. Grasses and shrubs can survive there because they have shallow roots. A sheet of mosses and lichens grows beneath these plants. When the soil above the permafrost thaws, the soil becomes muddy. Muddy soil is an excellent place for insects, such as mosquitoes, to lay eggs. Many birds spend the summer in the tundra to feed on these insects.

Answer:
Organisms that can make the food using simple substances are called autotrophs.
1. How can systems with such different structures perform the same function?
2. How can different structures perform the same function?
Please help! And explain your answer with evidence please!
Explanation: Specialized Structures. ... This is because different organisms have developed unique structures that perform these functions and that do so in ways that fit their specific environments. So in this case, the structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Due to unique structure an organism perform similar function if the structures are different.
Different structures perform the same function because different types of organisms have developed unique structures that helps them to perform function that is specific to their environments. The structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Analogous structures refers to those structures which perform same function, but have different structures. Such type of organisms belongs to different ancestry but their body parts perform similar function so we can conclude that due to unique structure an organism perform similar function if the structures are different.
