What are the environmental and economical
uses of soil?
Answer:
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

Some organisms, such as fish and mosquitoes, produce very large numbers of offspring. Why is producing a large number of offspring important for natural selection?
Answer:
Because a lot of the offspring die
Fish lay lots and lots of eggs but very few survive

In osmosis molecules move through a semi-permeable membrane from a high concentration to a low concentration. True or False
Answer:
False
Explanation:
Osmosis is the movement of water molecules through a selectively permeable membrane from high to low concentrations.
Diffusion is the process in which molecules move from an area of high concentration to low concentration.
The statement doesn't say that the molecules are water, so we put false. If it is wrong then tell the teacher that she has to include water molecules in there to be more detailed.

What needs to happen for natural selection to occur? Highlight all that apply.
A. Some of the traits will provide individuals an advantage over others.
B. Some variation occurs in the inherited traits.
C. A natural disaster.
D. Individuals with certain traits are more likely to have an increased number of offspring
Answer:
A
Explanation:
Natural selection occurs because those with more favorable traits survive while the others don't. If there are no favorable traits in a community then there is no natural selection.

Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?
Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.
Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:
Scale modelsScale populationsIn the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.
The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.
Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

Birds are most closely related to what other animals?

birds evolved from theropod dinosaurs, but in real time they are mostly

Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.

Answer: As vertebrate animals, birds are ultimately related to all the other vertebrate animals that live or ever have lived on earth. But you may be surprised to learn that the family of vertebrates to which modern birds are most closely related is the crocodiles , which evolved, like dinosaurs, from a population of archosaur reptiles during the late Triassic period.

27. City planners want to build a new airport. The city is located near a river that
often changes course. How could satellite views assist the planners in choosing
a location for the airport? (8.9C)
a. Views could be used to locate the areas of least vegetation
b. Views could be used to predict the future course of the river
c. Views could be used to locate flat and level areas
d. Views could be used to make topographic maps of the area
I
Answer:
d. Views could be used to make topographic maps of the area.
Explanation:
Satellite views helps the planners in choosing a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

Discuss which type of reproduction is the "best" strategy for continuing a species through time in a changing environment and justify your answer.
Answer:
Any sort of sexural reproduction.
Explanation:
Unlike asexual reproduction, sexual reproduction allows the species being produced to adapt the the changing environment around it to increase the chances of survival. For asexual reproduction, clones are made of the parent and, therefore, cannot withstand any extreme conditions that the parent species couldn't. For a changing environment, sexual is the best to allow the specimen and its offspring to change positively along with the environment.
