Explanation:
The statement that is NOT true of soils is: "All of Earth's systems are represented in a soil."
How much soil is important on earth ?Soil is a critical resource on Earth, as it is essential for supporting plant growth and providing a habitat for a wide variety of organisms.
While soils are complex and dynamic systems that interact with many other Earth systems, not all Earth systems are represented in a soil. For example, soils do not directly represent the atmosphere or the hydrosphere, although they interact with both of these systems in important ways.
The other three statements are true of soils:
Weathered parent material makes up most of the B-horizon: The B-horizon is typically composed of weathered rock and mineral fragments that have been transported downward from the A-horizon.
The C-horizon of a soil can contain unweathered rocks: The C-horizon is the deepest layer of a soil and can contain unweathered bedrock or other geological material.
Organic matter gives the A-horizon in a soil a dark color: The A-horizon is the uppermost layer of a soil and is often darker than lower layers due to the presence of organic matter, which can give it a dark brown or black color.

A student wants to know the effect a mutation might have on a species' survival. The change causes a rabbit to have mottled brown fur. The student runs a computer simulation for ten generations. What possible conclusions can you draw? Choose ALL that apply
Answer:
A) Evolution occurred because the allele frequency changed over time.
C) The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E) The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
Explanation:
Based on the data, you can conclude:
Evolution occurred because the allele frequency changed over time.
The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
The possible conclusions that can be drawn are
evolution that occurred due to the allele frequency.Rabbits with mottled brown fur have a selective advantage.The mutation had a positive effect.What is mutation?The mutation is a change in the DNA sequence that results from the copying mistakes that tke place during the cell division and the exposure to the radiating agent, exposure to virus and chemicals also leads to the cases of gene mutation.

(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location
where the process occurs.
Answer:
Explanation:
mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.
FGF5 is a gene that is encoded in the DNA.
mRNA is a messenger molecule, which transcribes the information from DNA and delivers it to the RNA.
Role of mRNA Transcription is the process of decoding the message delivered by DNA into a messenger molecule of RNA. The enzyme RNA polymerase is involved in creating the RNA molecule.
FGF-5 gene is produced in the outer root of the hair follicle and perifollicular macrophages. The mRNA produced is complementary to the template DNA and copied all the information of the DNA.
The mRNA is then capped and sent to ribosomes for further translation. The gene is encoded in the DNA.
Thus, transcription is the process in which the mRNA is complementary to the template DNA strand copying all the information.

Which does NOT describe acid precipitation?
Multiple choice question.
A)
It increases when air pollution levels are low.
B)
It decreases the pH of lakes and other bodies of water.
C)
It can form when moisture combines with sulfur dioxide from power plants.
D)
It can be rain or snow.
Answer:
c
Explanation:
the moisture that has the sulfur will go through evaporation and then rain
"It can form when moisture combines with sulfur dioxide from power plants" is not observed in acid precipitation, hence option C is correct
One of the effects of air pollution is acid rain. Fuel combustion generates gases that combine with oxygen in the air and water vapor to create acids that eventually fall as rain on the earth's surface.
Any type of precipitation with high concentrations of nitric and sulfuric acids is referred to as acid rain. Snow, fog, and little pieces of dry material that fall to Earth can likewise represent it. Acid rain typically has a pH between 4.2 and 4.4, whereas normal rain has a slightly acidic pH of 5.6.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]

What happens during the 4 stages of mitosis
Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...
