Answer:
Jack i right
Explanation:
it seems awfully strange if only one type of material makes up the whole soil.. obviously the soil will consist of more than one. most soil is made up of minerals, rocks and organic matter , remember that they have several particles within them with different measurements.

answer these questions asap please.
Answer:
I think energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, The thermal energy is used to heat water, which is pumped through a system of pipes and radiators. A warm-air heating system burns fuel in a furnace to produce thermal energy. The thermal energy is used to heat air, which is forced through a system of ducts and registers. A thermostat controls a home heating system.

Which of these locations on Earth experiences the least change in the number of daylight hours throughout the year?
Answer:
The Northern Hemisphere has the fewest hours of daylight, and the North Pole is tilted away from the sun.
Explanation:
The north pole experiences the least change in the number of daylight hours throughout the year.
The sun is always shining at the north pole. When the Earth’s north pole is tilted towards the Sun, Earth’s south pole is tilted away from the Sun. People living in the southern hemisphere experience shorter days and colder winters.
The northern half of the Earth is tilted towards the Sun for a portion of our orbit. This is the summer season in the northern hemisphere.
In the northern hemisphere, the days are longer, the sun is higher in the heavens, and the Sun’s rays hit the Earth’s surface more directly, warming the planet. The north pole has constant daylight.

A Giant factory farm uses large open lagoons to treat waste from the buildings where hogs are stored. The problem is that the lagoons smell awful and, during rainstorms, they are at risk of spilling into surrounding river systems. Design a solution that resolves the smell and water contamination risk and allows the farm to continue to raise hogs.
Build up a wall around the lagoons a little bit to keep it from spilling over make the wall about 5-ish feet tall and made of concrete. as for the smell i can't quite figure it out but if they have air filtration systems and somthing that releases a good smell it will at least help the smell be a little better.

When writing a research paper, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your research paper is credible.
Use sources that end in .gov. These government sites are reliable sources. You can also use sites ending in .edu. They’re generally trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions:
Who authored the document?
Is the author a genetics expert?
What is the document’s purpose?
Does the document state facts that scientists can prove with evidence?
Does the document include opinions?
How old is the document?
Do other credible sources support the document’s statements?
Search for credible websites and note the information they contain. Write down two sources that you’ll use for your research paper, and cite them using Modern Language Association (MLA) citation methods.
A sample citation of sources using the MLA citation methods is Author(s). "Title of Article." Title of Periodical, Day Month Year, pages.
What is a Research Paper?This refers to the expanded essay that is written in order to find answers to research questions in an academic writing format.
Hence, we can already see that a list of reliable sources has been mentioned already and the important questions to ask when using sources for a research paper.
Therefore, we can see that when using Modern Language Association (MLA) citation methods, one should place the name of the author(s) in alphabetical order, then the title of the article, day, month, and year, then the pagination.

read the story below about Chloe and Khalil, two students from another school who are also learning about the Earth, Moon, and sun. Then, answer the question below.
Chloe is a photographer for the school paper. After learning about Eric Wu’s assignment for About Space magazine, she decided to try to take her own picture of a lunar eclipse for the school paper. However, on the night of the lunar eclipse, Chloe wasn’t feeling well, so her parents wouldn’t let her go outside with her camera.
The next day at school, Chloe was feeling disappointed, so her friend Khalil tried to cheer her up. “Don’t worry,” he said. “Remember, we learned that the Moon moves in the same circle around Earth each month. That means you can photograph a lunar eclipse when Earth is in between the sun and the Moon again next month.”
“Maybe, but maybe not,” Chloe said. “A lunar eclipse happens sometimes when Earth is in between the sun and the Moon, but not always. It could be a long time before I have another opportunity to take a picture of a lunar eclipse.”
When can a lunar eclipse be photographed?
Claim 1: A lunar eclipse can be photographed any time Earth is in between the sun and the Moon.
Claim 2: A lunar eclipse can be photographed sometimes when Earth is in between the sun and the Moon.
Answer: Claim 2
Explanation: Since the moon is in earth's orbit and the earth is tilted on an axis sometimes there won't be a lunar eclipse.
Answer: Claim 2
Explanation: Since the moon is in earth's orbit and the earth is tilted on an axis sometimes there won't be a lunar eclipse.

what do you put into the punnett square and what is the percent of black and white fur?
Answer:
The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents.
to find the percent:
Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
