Show all your work!
Answer:
80N
Explanation:
in both sides, pressure is the alwyays the same whatever the area is..
First we calculate the pressure at piston A:
P= F÷a
given that,
#F= 20N
#a=1m^2
P= 20÷1
P= 20 Pa.
At piston B:
pressure is the same = 20Pa
Area= 4m^2
P=F/a
F= P×a
F= 20 × 4
F= 80N
A decrease in the decomposers within an ecosystem would have what effects on the carbon cycle?
Answer:
There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support.

Whoever awnsers gets Brainliest!!! What causes a star to shine brightly?
the color that is produced
the energy that is released
the amount of gravity that is present
the types of elements that are present
Answer:
the energy that is released
Explanation:
heat gives off light, and the heat comes from the reactions in the star that produce the energy
Answer:
The energy that is released.
Explanation:
The source of most stars' energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium which makes the stars shine brightly.

9. The prefix mono- means "one" and the prefix poly-
means "many." Some lipids are monounsaturated, and
others are polyunsaturated. Explain the difference
between the fatty acids in these different types of lipids.
Answer:
Monounsaturated Fats: This type of unsaturated fat contains only one double bond in its structure.
EXAMPLE: Stearic acid having chemical formula= C18H36O2
Polyunsaturated Fats: This type of unsaturated fat contains two or more double bonds in their structure.
EXAMPLE: Lenolic acid having chemical formula= C18H32O2

what is the universal system of units among scientists
Answer:
International System of Units (SI)
Explanation:
The measurements that scientists use are based on the International System of Units (SI), which is a form of the metric system. The term SI is shortened from the French term Le Système international d'unités. It is the world's most widely used system of units, both in science and business. Hope this helped!

Which is observation proves that a cell is a eukaryote?
A.it has DNA in the cell
B.it has ribosomes inside the cell
C.it has enclosed organelles inside the cell
D.it is surrounded by a cell membrane
Answer:
The answer is C
Explanation:
Only eukaryotic cells have membrane-bound organelles, so that would be proof that the cell is a eukaryote.

Succession describes the sequential appearance and disappearance of species in a community over time after a severe disturbance. In primary succession, newly exposed or newly formed rock is colonized by living organisms; in secondary succession, a part of an ecosystem is disturbed and remnants of the previous community remain especially soil. In both cases, there is a sequential change in species until a more or less permanent community develops. What is the process of ECOLOGICAL SUCCESSION? *
Answer:
The answer will be listed below.
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less predictable changes following a disturbance or the initial colonization of a new habitat.

What are three ways energy is used by the organisms?
Answer:
Organisms use energy to survive, grow, respond to stimuli, reproduce
Explanation:
Three ways energy is used by the organism are food, nutrients, and sunlight.
What are living organisms?Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.
Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.
Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.
Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

How do scientists use the electromagnetic spectrum to view our universe? Would we be able to see some objects in the universe if we only used the visible spectrum? Explain.
Answer:
Explanation:
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas.
Is Protein a short term energy source or a long
term energy source?
Answer:
short term
Explanation:
Short-term response energy storage devices are usually applied to improve power quality, particularly to maintain the voltage stability in power systems, throughout a contribution during transients (few seconds or minutes) [4].

Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not react the same chemically. Which of the following generalizations can explain this? (5 points)
a
Monosaccharides serve different cellular functions, and they are only involved in reactions in which they are needed.
b
The atoms of monosaccharides are arranged differently, and the different shape gives each monosaccharide unique properties.
c
Monosaccharides have different properties, but the disaccharides they form when combined with other molecules will have the same properties.
d
The atoms of monosaccharides are arranged similarly, but the monomers from which they are formed have different physical and chemical properties.
Answer:
B
Explanation:
Monosaccharides are the simplest carbohydrates. Although glucose and fructose have the same molecular formula they have different structures or the atoms are arranged differently from each other and this is evident in the way they react, behave and in their properties.

nucleus and eukaryotic cells do not.
Answer:
I think it's D, because prokaryotes have no organelles, yet their DNA can be enclosed in a small nucleus (nucleolus).
