Answer:
1. 0.24255319g/l
2. 2.7g/cm^3
3. 1.3g/ml
(im not sure about the units of measurements)
Explanation:
1. density = mass/volume
5.7g/23.5l = 0.24255319g/l
2. d=m/v
m=2700g, v= 20x5x10 = 1000cm^3
= 2700/1000= 2.7g/cm^3
3. d=m/v
m= 78g, v= 60ml
= 78/60 = 1.3g/ml
A student constructs a model using a fan and a pile of sand shaped like a dune. The student turns on the fan, observes the model for changes, and lists several conclusions in a chart.
1. Wind cannot erode landforms.
2. Wind can reduce the surface heights of landforms
3. Wind cannot transport materials
4. Wind cannot weather materials.
Answer: Im sorry i dont kno
Explanation:
Based on the observations of the sand dune model with a fan, the conclusions provided in the chart are incorrect. In reality, each statement's opposite is true.
What is Sand dune?A sand dune formed by wind or water flow is known as a sand dune. When there is a lot of loose sand present and the wind or water is powerful enough to shift the sand grains, sand dunes emerge. Beaches, deserts, and some riverbeds all contain sand dunes.
Based on the observations in the provided example, the following inferences are correct:
Landforms can be eroded by wind.Sand can be moved by wind and dumped elsewhere, altering the size and shape of landforms.Sand and other materials are transported from one location to another by wind, which is a significant agent of sediment transport.Materials can weather and degrade in the wind through abrasion and deflation.Therefore, the conclusions given in the chart are false based on the observations of the sand dune model.

Which type of succession take less time and why?
Answer:
Explanation:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

use the concept of natural selection to explain why organisms typically adapt over time
Answer:
natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species
Explanation:
Answer:
Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species. Eventually, the more favorable traits are incorporated into a species as the organisms that had those traits survive while the ones who do not die. This process takes time because it occurs through individuals with the favorable traits passing those traits on to future generations. Typically, the less favorable traits will not be eradicated in one generation.

Answer:
1.The science method has 5 basic steps.
2. Make an observation. Ask a question. Test your hypothesis. Collect data. Examine the results. Draw conclusions. Report the results.
3. Science is the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
4. Pseudo-science is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
5. Pseudoscience is differentiated from science because - although it usually claims to be science- pseudoscience does not adhere to scientific standards , such as the scientific method, falsifiability of claims, and Mertonian norms.
6. The tragedy of the commons refers to a situation in which individuals with access to a shared resource (also called a common) act in their own interest and, in doing so, ultimately deplete the resources. ... In 1968 the term "Tragedy of the commons" was used for the first time by Garrett Hardin in Science Magazine.

Scientists believe that green crabs , originally from Europe, reached U.S. shores in the mid-1800s after riding across the Atlantic in the ballast water on ships. Once here in North America, they travelled to Maine, where they have been present for more than a century. Green crabs are a non-native, or invasive species, organisms that have been transported via human activities and introduced to locations in which they previously did not occur. The green crab population in some areas of Maine has increased dramatically in recent years, and they have been feeding on shellfish resources such as blue mussels and soft-shell clams, threatening the state's third-largest wild fishery. The increase in the green crab population has coincided with an increase in ocean temperatures. A similar cycle occurred in the early 1950s when the ocean temperatures rose and the green crab population increased, devastating the soft-shell clam resource in Maine. What can be done to mitigate the environmental impact of this invasive species
Answer:
b
Explanation:
i got the queston right
Green crabs are exotic species is being transported through human activities. It can be mitigate by controlling their spread.
What are green crabs?Green crabs are extremely rare in the environment. These are efficient predators and prey on clams and scallops and destroy sea-grasses by hunting and burrowing.
One must focus on the regulatory efforts for reducing green crab populations rather than focusing their management as commercial fishery.
Work should be done along with the industry and municipal shellfish programs to monitor and control the spread of green crabs.
Thus, the control of their population can help mitigate the environmental impact of this invasive species.
