Answer:
A dependent variable is a variable whose value depends upon some other variable where as, an independent variable is a variable whose value doesn't depend upon any other variable.
Explanation:
For example:
Let us take an expression y=3x+1, where x has some given values { let's assume x lies between 0 to 100}
so we can see that the value of y is depending upon the value of x ,as for every different value of x we will get a different value of y. So we can say that y is a dependent variable.
On the other hand, x doesn't depend on y as its values are already mentioned or specified so it's an independent variable.
Answer:
A dependent variable is a variable whose value depends upon some other variable where as, an independent variable is a variable whose value doesn't depend upon any other variable.

Explain why inmates who have been in the dark cell for quite long usually have problems with their eyes and usually squint when in bright light?
Answer:
No one can see in total darkness. Fortunately, there’s almost always some light available. Even if it’s only dim starlight, that’s enough for your eyes to detect. What’s truly amazing is how little light is required for you to see.
Human eyes have two main features that help us see better in low light: the pupil’s ability to change size, and the eye’s two types of light-sensing cells.
Opening up to let in more light
Your pupils are the black areas at the front of your eyes that let light enter. They look black because the light that reaches them is absorbed inside the eyeball. It’s then converted by your brain into your perceptions of the world.
You’ve probably noticed that pupils can change size in response to light. Outside on a bright sunny day, your pupils become very small. This lets less light into the eye since there’s plenty available

In what part of the cell cycle does the DNA make a copy of itself?
A. Interphase
B. Prophase
C. Telophase
D. Cytokinesis
Correct Answer: A. Interphase
Explanation: The replication of DNA occurs during interphase. Arguably, the replication of DNA is the most important step in the cell cycle, as it allows the cell to pass on a full copy of its DNA to each daughter cell. If this step did not occur, each daughter cell would only receive a portion of the parent DNA.

is turning a liquid to a gas a chemical reaction
Answer:
Yes. It's called condensation.
Explanation:
Nope.
Turning a liquid to a gas is not a chemical change...its a physical change vecause it is going from a liquid phase to a gas phase. A physical change can be be reversible and irreversible. Therefore vaporisation is a physical change (liquid 2 gas).

8. All of the following are true of surface currents except (1 point)
Othey are influenced by wind.
Othey can exist in large lakes.
Othey are found in the top 1,300 feet of the ocean.
Othey have the same movement as thermohaline currents.
Water current involves surface or deep water circulation. Surface currents are influenced by winds and occur in the top 1313 feet of depth. Statement 4 is false. They have the same movement as thermohaline currents.
-----------------------------------------------
Many different factors can produce water currents in lakes and oceans. Some of these factors are
winds, temperature, salinity, earthquakes, and storms.When talking about water circulation, there are two main types of movements,
Surface circulation, which occurs from 0 to 400 meters deep (up to 1313 feet aproximatelly)Deep circulation, which occurs at depths that super 400 meters.Surface circulation is closely related to horizontal water movements, while deep circulation is related to vertical ones.
→ Horizontal water movements
They are produced by the action of different winds on the surface. Superficial winds, influenced by the Coriolis effects, are responsible for most of the marine currents. Trade winds push the water surface forward western direction in the equator, while western winds produce currents that move water to the east at higher latitudes.By the Coriolis effect, water masses are deviated to the west or the east, depending on the hemisphere, resulting in large clockwise circular turns in the Northern Hemisphere and the opposite direction in the Southern Hemisphere.Warmer currents travel from the tropics, along the continental margins, carrying warm water to higher latitudes, and as they do so, these water masses get cooler, producing cold currents.
→ Vertical movements
They can be related to density, salinity, and temperature. Variation of these factors causes thermohaline currents, which move water vertically, transporting cold water with nutrients from the bottom to the surface.According to this resumed framework,
→ Surface currents ⇒ horizontal movement ⇒ up to 400 m depth ≅ 1313 feet
→ Deep currents ⇒ vertical movement ⇒ more than 400 m depth.
OPTIONS
they are influenced by wind ⇒ TRUE they can exist in large lakes ⇒ TRUE they are found in the top 1,300 feet of the ocean ⇒ TRUE they have the same movement as thermohaline currents ⇒ FALSE------------------------------------------------------------------------

An Apple is Resting on a table.Claire says that there are no forces acting on the apple because it is not moving.is she right?
Answer:
Claire is wrong.
Explanation:
Claire is wrong because gravity always acts upon a resting object.
An apple is resting on a table. Claire says that there are no forces acting on the apple because it is not moving. She is wrong because the resting objects have their gravitational force, which is applied by the earth.
What is force?
Energy is defined as the potential to perform a work, whether it is a simple or complex one, and each work needs a different amount of energy. If an object, such as the apple on the table, remains motionless or at rest, it gains potential energy but the force is applied on it. The substance has the kinetic energy such as a rolling apple when it moves.
The substance moves in the direction of the force applied. The movement of a substance depends on its mass and the force applied to it. If a mass of 10 kg is maintained, it will require more energy to push the substance weighing 2 kg.
Hence, she is wrong because the resting object, which is the apple, has its gravitational force.

halogens
Nonmetals
I wanted to let the other guy get brainliest, and now they can :)
Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.
What are nonmetals?A nonmetal is an element that lacks the characteristics of a metal. It is characterized by what it is not rather than by what it is. It doesn't have a metallic appearance, can't be formed into a wire, bent, or pounded into shape, has a low melting or boiling temperature, and isn't good at conducting heat or electricity.
On the periodic table, nonmetals make up a small portion and are mostly found on their right side. The one exception is hydrogen, which appears in the upper left corner of the periodic table and behaves as a nonmetal at ambient temperature and pressure. Hydrogen is projected to behave like an alkali metal under high pressure.
Therefore, Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.

Explanation:
If radio active substance that weight5600grams and half-lifeof 100years is left with 700 grams for how long has the decaying activity been undergoing?
Answer:
If you have a 120 gram sample of a radioactive element, how many grams of that element will be left after 3 half-lives have passed?
Solution
Given: mass of radioactive sample of an element, number of half-lives
Asked to Solve For: mass of radioactive element after so many half-lives
Solve:
All radioactive samples lose half of their mass after each half-life. Thus, one solution is to calculate the mass after each half-life. (This method only works if you are asked to solve for a whole number of half-lives). Let the passing of time equal to one half-life be represented by and arrow, →. Then the solution is:
120 g → 60 g → 30 g → 15 g
If you want to solve for any number of half-lives, including fractional half-lives, then you use the equation: amount remaining = (12)n(amountatstart) , where n= number of half-lives. Then the solution is:
amount remaining = (12)3(120g)=15g
