CH3OH + HOCH3 = CH3-O-CH3 + HOH Is this reaction an addition reaction or a dehydration reaction or synthesis or whatever? A. Addition B. Dehydration Brainliest for the correct answer. Pls help
Answer:
B. Dehydration
Explanation:
Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.
Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.
For example: RCO2H + R′OH ⇌ RCO2R′ + H2O
In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH
The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.
Hence, the correct option is B. Dehydration.

How is a clade differentiated from another clade
Answer:
A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.
Explanation:
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades
Answer:
A clade is a monophyletic grouping in which all the organisms stem from the same branching point.
Explanation:
The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.
What effect will the settling of sediment have on the shape of the stream?
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

In recent years, scientists have collected data on the extent of sea ice in the Arctic Ocean as shown in the graph. What additional data could be used to support or refute the theory of global climate change?
O A graph providing data on daily temperature fluctuations from 1980 to 2010
O A graph providing data on average global temperatures from 1980 to 2010
O A graph showing monthly fluctuations in sea ice extent for each year 1980 to 2010
O A graph showing yearly fluctuations in sea ice extent for each year 1980 to 2010
Answer:
Option 2, or B
Explanation:
The most practical data would be global temperatures during the 37+ year time period to coincide with the thinning sea ice. Option #1 is far too broad to include (daily), as is option #3 (monthly). The last option is basically proposing to duplicate what the graph already shows.
The additional data that could be used to support or refute the theory of global climate change is as follows:
A graph providing data on average global temperatures from 1980 to 2010.Thus, the correct option is B.
What is Climate change?Climate change may be defined as the long-term shifting or alteration in the average temperatures and weather patterns.
The graph given below illustrates the average temperature from 1980-2010. It is not possible to represent the daily or monthly average temperature of approximately 30 years.
Therefore, the correct option for this question is B.

Humans are actually producing more carbon dioxide than natural sources can absorb. That means the atmosphere is not at a steady state. Scientists and engineers are researching ways to remove carbon from the atmosphere faster than the current rate. This process is called carbon sequestration. If humans increase their rate of carbon emissions but also increase the rate of carbon sequestration by the same amount, what effect will that have on the residence time of carbon dioxide in the atmosphere? What effect will it have on the total amount of carbon dioxide in the atmosphere?
Answer:
no effect on the atmosphere
Nigerian way
Answer:
What effect will that have on the residence time of carbon dioxide in the atmosphere?
Individual Carbon Dioxide molecules will be in the atmosphere for less time as it is rapidly being cleared and produce.
What effect will it have on the total amount of carbon dioxide in the atmosphere?
None, because humans are producing more as they remove it.
