What is the greenhouse effect?
Answer:
the greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.

At convergent boundaries of tectonic plates a process occurs where one plate either is forced or sinks under another plate. This process is called
Select one:
reduction
induction
subduction
convection
Answer:
subduction
Explanation:
Subduction is a geological process in which the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle.
what are the first 3 rules that Newton made??
Answer:
Newton's Laws of Motion
Explanation:
1st- Inertia- every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
2nd- The second law states that the greater the mass of an object, the more force it will take to accelerate the object
3rd- action reaction- If the forces are equal in opposite directions, the object will not move. The forces cancel each other out so that the acceleration is zero. If one force acting in one direction is greater than the force acting in the opposite direction, the object will move.
which beaker has the least thermal energy?
please don't guess, i already got 1 question wrong, i dont want a 60 on this.
Answer:
It's B. beaker A
Explanation:
The thermal energy is directly proportional to to the mass of the solution times the temperature difference
In other words more mass and temperature means more thermal energy
So less mass (or mL of solution in our case) and less temperature means less energy
This means we choose the beaker A
Hope this helps have a good day

Answer:
Cell Membrane Function: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Description:The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Nucleus Function:The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.
Description: The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
Explanation:
Answer:
The cell membrane is the semipermeable membrane of a cell that surrounds and encloses its contents of cytoplasm and nucleoplasm. The cell membrane separates the cell from the surrounding interstitial fluid, the main component of the extracellular fluid
A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
Proxima Centauri and the Sun are both main-sequence stars, but Proxima Centauri is a red dwarf and the Sun is a yellow dwarf. Based on the information you charted, compare the characteristics of red dwarf stars and yellow dwarf stars, please help
Answer:
red dwarf stars have a very low mass while yellow dwarf stars have a very high mass
Explanation:
the reason for this is because red dwarf stars burn at a cooler temperture and are smaller. the oppisite for yelow stars
The word igneous comes from the Latin word for fire. However, the name is inaccurate. The rocks are not created with flames. Instead, they are created when magma cools and hardens. Magma is hot molten rock found deep in the earth. Igneous rock is either intrusive or extrusive. It is intrusive when it forms inside the earth's crust. It is extrusive when it is formed above the earth's surface.
Select the sentence from the passage that supports the idea that temperature is an important factor in the formation of igneous rock.
Question 10 options:
Instead, they are created when magma cools and hardens.
The word igneous comes from the Latin word for fire.
Magma is hot molten rock found deep in the earth.
It is intrusive when it forms inside the earth's crust.
Answer:
Instead, they are created when magma cools and hardens —> the temperature contributes as the magma would be at extreme heat while it need a cooler temperature to harden and mold

Think about "The Law of Conservation of Mass" (In a chemical change, the total mass of the new substances is always the same as the total mass of the original substances.) Why might it be difficult to demonstrate this law in chemical changes where one or more of the products is a gas?
Answer:
The Law of Conservation of Mass states matter cannot be created/destroyed in a chemical reaction
It is hard to prove the law because the gas molecules move out the area quickly, at a higher speed than liquid or solid particles.
If their appears to be a loss in mass, it is because of the above, and that is why it may be difficult to demonstrate this 'law'.

Why do scientists use spiral tubes instead of straight ones?
Answer:
Heat and mass transfer of a LiBr/water absorption heat pump system (AHP) was experimentally studied during working a heating-up mode. The examination was performed for a single spiral tube, which was simulated for heat transfer tubes in an absorber. The inside and outside of the tube were subjected to a film flow of the absorption liquid and exposed to the atmosphere, respectively. The maximum temperature of the absorption liquid was observed not at the entrance but in the region a little downward from the entrance in the tube. The steam absorption rate and/or heat generation rate in the liquid film are not constant along the tube. Hence the average convective heat transfer coefficient between the liquid film flowing down and the inside wall of the tube was determined based on a logarithmic mean temperature difference between the tube surface temperature and the film temperature at the maximum temperature location and the bottom. The film heat and mass transfer coefficients rose with increasing Reynolds number of the liquid film stream.
