Which of the following facts about the ocean water indicates that the ocean is a major resource of nutrients?
A.
Nearly a third of the world's known oil resources are found underneath the ocean floor.
B.
100 mL of ocean water contains millions of bacteria and hundreds of thousands of phytoplankton.
C.
The oceans cover almost three-fourths of the world's surface.
D.
Ocean water becomes denser as its salinity increases or its temperature decreases.
In an ecosystem comprising of the oceans, the fact the ocean is a major resource of nutrients is that 100 ml of ocean water contains millions of bacteria and hundreds of thousands of phytoplankton.
What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

How does the mass of and distance between the Sun and the Earth impact the number of days in a year?
Answer:
Gears A and B work together. Gear A turns 30 times when Gear B turns 45 times. When Gear B turns 12 times, how many times does Gear A turn?
We use Kepler's third law to find the correct answer is:
The period (year) of the plant increases with increasing distance to the Sun The period is independent of the mass of the Planet The period is inversely proportional to the masses of the SunKepler's third law is a direct application of second Newton's law the motion of the planets around the Sun, if we assume that the orbit is circular the deduction is
F = m a
where F is the force of attraction between the Sun and the planet, m is the mass of the planet and a is the ccentripetal acceleration.
The force is given by universal gravitation law, which says that the force of attraction between two bodies is directly proportional to the mass of the bodies and inversely proportional to the square of the distance between them, this force is attractive
F = [tex]G \frac{M \ m}{r^2}[/tex]
where G is the universal constant of attraction, M the mass of the Sun, m the mass of the plant and r the distance between them
From kinematics we know the expression of the centripetal acceleration
a = [tex]\frac{v^2}{r}[/tex]
we substitute
[tex]G \frac{M \ m}{r^2 } = m \frac{v^2}{r}\\G \frac{M}{r} = v^2 \\[/tex]
As we assumed a circular orbit, the velocity of the planet in the orbit is constant, so the kinematic relations of uniform motion can be used.
The distance traveled by the planet is the length of the circle
d = 2π r
v = d / T
where T is the period of the orbit
v = 2π r / T
we substitute
[tex]G \frac{M}{r} = \frac{4 \pi ^2 r^2 }{t^2}\\T^2 = ( \frac{4 \pi ^2}{G \ M} ) \ r^3[/tex]
The year is the duration of the period of the planet's orbit around the Sun, with the previous expression it is observed that the period (year) increases when the radius of the orbit increases with a power of 1.5, in summary the planets more far away has duration of the greater anus
The constant in parentheses is inversely proportional to the greater of the Sun, that is, for more massive stars the period decreases
The period is in dependent on the mass of the planet, therefore any object at the same distance has the same duration of the period or the year of the planet.
In conclusion we use Kepler's third law to find the correct answer is:
The period (year) of the plant increases with increasing distance to the Sun The period is independent of the mass of the Planet The period is inversely proportional to the masses of the Sun.

What purpose does air conditioning serve?
Answer:
AC does more than just keep you cool
Explanation:
For most people, the most important function of an air conditioner is its cooling power. However, cooling is in reality just one of the 3 vital functions of an AC system.
Most air conditioning systems use underground pipes to store and reject heat. To generate a climate in a room that is comfortable for people, air conditioning is mostly used.
What is air conditioning?The term "air conditioning" is frequently used to refer to the machinery employed in the process of eliminating heat, cold, plus moisture from the inside of a populated place.
The exterior unit's compressor liquefies the refrigerant during cooling to remove heat. Conversely, while heating a room, heated pressure gas produced by the outside unit's heat exchanger or compressor is condensed enough heat the air. Most air conditioning systems use underground pipes to store and reject heat. To generate a climate in a room that is comfortable for people, air conditioning is mostly used.

Explanation:
it was observed that the atoms of a substance had so much energy that it separated the electrons and protons of the atom what is most likely the state of matter of the substance? gas liquid plasma solid
Answer:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products.
Explanation:
The state of matter of the substance where in the electrons and protons are separated from the atom is plasma.
What is matter?
Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume . The matter is composed up of atoms which may or not be of same type.
Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.Matter can neither be created nor destroyed which is given by the law of conservation of matter.

ok yall l have to write a essay about Pretend that you are the moon. What would you say? Describe yourself to others based on what you have learned about the moon in class. How does your surface reflect light? Do you always look the same? How long does it take you to revolve around the Earth? Do you have an axis like the Earth? Where do you go during the day? What would you see in space?
can yall do it for me
Answer:
If I was the moon, I would say that space is amazing. Past the years, I had been walked on by many people. I think they are called astronauts. The first person that put their feet on me was Neil Armstrong. He had a white thick coat and a helmet. I had been flagged by Buzz Aldrin but, the flag been flat on the ground since the moment Aldrin and Neil Armstrong lifted off. I couldn't do anything about it but, that flag made me feel special. I remember that the flag had about 50 white stars on the corner, in the corner was filled with blue where the stars were, red, white stripes. I shine because my surface reflects light from my friend, the sun. Many people ask me, "Do you always look the same?" No, everyone sees the same phases of me, the moon. I go through a process called moon phases. They are first Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent, New Moon. I rotate on my axis. One rotation takes nearly as much time as one revolution around Earth I believe. During the day, I go the the other side of the earth, where the Earth's shadow is. Honestly, I enjoy being the moon. It's fun and I enjoy the white little twinkling stars beside me. I like seeing that little world move.
A student’s experiment showed that her egg gained mass overnight with the vinegar and distilled water. She had about a +1% change for distilled water. She had hypothesized that the egg’s mass would not change significantly with vinegar. She concluded that her hypothesis about vinegar was not supported because it did change in mass. Her teacher told her that the data indicated that her hypothesis was supported, especially with the 10% change for the distilled water. What did the teacher mean?
