How does the use of fertilizer affect the nitrogen cycle?
God bless all and stay safe! :) :)
Answer:
Nitrogen from fertilizers sinks into soils, often creating conditions that favor the growth of weeds rather than native plants. Nitrogen then washes into waterways, causing a surplus of nutrients, a situation called eutrophication.

Do plants have to do cellular resperation? why or why not?
Explanation:
Like all other organisms, plants require energy to grow and thrive in their environment. The process of cellular respiration allows plants to break down glucose into ATP.
Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.

Answer:
1. The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice (usually 20 or 21 June).
2. The Sun lies directly over 23 1/2o south. Occurring during the astrological sign of Capricorn, 23 1/2o south latitude is called the Tropic of Capricorn. Continuing to March 21st (i.e. spring equinox) the Earth has positioned itself similar to that which occurs in September, only on the other side of the Sun.
3. June 21
The latitude of 23 ½ degrees north is known as the Tropic of Cancer, and it is the northern boundary of the tropics. Question: On June 21, the subsolar point is at about 23 1/2 degrees north.
4. In 2020, the Sun will cross the celestial equator from north to south on September 22, at 13:30 UTC. Because of time zone differences, the equinox will take place on September 23, 2020 at locations that are at least 10:30 hours ahead of UTC.
5. December 21st was the Winter Solstice in the northern hemisphere. That's the day when Earth's north pole was pointed completely away from the Sun. If you lived north of the Arctic Circle, like Santa Claus, you would have experienced 24 hours of darkness. It was the day Sun never rose.
6. The farthest south that the sun's rays shine directly is latitude 23 ½ degrees south, the Tropic of Capricorn. This is the southern boundary of the tropics. On this day, the area north of the Arctic Circle gets no sunlight, and the area south of the Antarctic Circle gets 24 hours of light.
7. Tropic of Capricorn, 23 1/2 degrees S. Tropic of Cancer, 23 1/2 degrees N. Arctic Circle, 66 1/2 degrees N. Antarctic Circle, 66 1/2 degrees S. North Pole, 90 ...
8. Tropic of Capricorn: 23.5 degrees south of equator. ... at midday on December 21 is 90-36-23.5 = 30.5 degrees; on March 21
9. equator
The equator is an imaginary line drawn right around Earth's middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. Another imaginary line drawn straight through Earth connecting the North Pole to the South Pole is Earth's axis of rotation.
10. A day is the amount of time it takes a planet to finish one rotation on its axis. It takes Earth approximately 365 days and 6 hours to orbit the Sun. It takes Earth approximately 24 hours — 1 day — to rotate on its axis. So, our year is not an exact number of days.
Explanation:
Answer:
Antarctic Circle - 23 ½ degrees north of the South Pole
solstice - Latin root word meaning sun stands still
June 21 - summer solstice
September 23 - fall equinox
Tropic of Capricorn - 23 ½ degrees south of the equator
Arctic Circle - 23 ½ degrees south of the North Pole
March 21 - spring equinox
Tropic of Cancer - 23 ½ degrees north of the equator
equinox - Latin root word meaning equal night
December 21 - winter solstice
Explanation: At this time, the sun's closest and most direct rays strike the earth along a line 23½ degrees south of the equator. This line is called the Tropic of Capricorn. As you can see in the diagram, an area around the North Pole will not receive sunlight at all. The imaginary line of the Arctic Circle encloses this area. The Arctic Circle is only 23½ degrees south of the North Pole.
Around the South Pole lies an area which has twenty-four hours of daylight on December 21. This area is bounded by the Antarctic Circle, which is 23½ degrees north of the South Pole.
The equator is now south of the most direct rays of the sun, and the sun shines straight down on the imaginary line called the Tropic of Cancer, which lies 23½ degrees north of the equator. Summer is the season in the Northern Hemisphere, when winter is the season south of the equator. People who live in the Southern Hemisphere have their longest night of the year of this date, and those in the north have their shortest night.
(The word solstice comes from the Latin root words which mean "sun" and "to make stand still.")
(The word equinox comes from the Latin root words which mean "equal," and nox, which means "night.")

Why do prokaryotes not undergo mitosis?
The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Base your answer on the passage below
Avian (Bird) Flu
Avian flu virus H5N1 has been a major concern recently. Most humans have not been exposed to this strain of the virus, so they have not produced the necessary protective substances. A vaccine has been developed and is being made in large quantities. However, much more time is needed to manufacture enough vaccine to protect most of the human population of the world.
Most flu virus strains affect the upper respiratory tract, resulting in a runny nose and sore throat. However, the H5N1 virus seems to go deeper into the lungs and causes severe pneumonia, which may be fatal for people infected by this virus.
So far, this virus has not been known to spread directly from one human to another. As long as H5N1 does not change to another strain that can he transferred from one human to another, a worldwide epidemic of the virus probably will not occur.
3.Identify one event that could result in the virus changing to a form able to spread from human to human.
As the virus goes from bird-to-bird and bird-human. The virus may become unstable enough and mutate like crazy. One of those mutations could be like lethality or severity, But more important, human-human spreading.

What are the 2 ways plants use energy?
Answer:
What are the 2 ways plants use energy?
Explanation:
This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.
Answer: Plants use solar energy (or energy from the sun) to change water and carbon dioxide into a sugar called glucose. Another source of energy is Chemical energy.
Explanation: Or in short terms. Solar and chemical
What is the other vacuole a paramecium has and what is its purpose?
