Answer:
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.

In passive transport, molecules move__ the concentration gradient.
Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.

12. Compare and Contrast the relationships between the speed of electromagnetic
and mechanical waves as they travel through different mediums. YOU must
write at least 8 sentences.
Answer:
Compare and Contrast the relationships between the speed of electromagnetic and mechanical waves as they travel through different mediums is explained below in details.
Explanation:
As per the mechanism, the waves can be distinguished as electromagnetic and mechanical waves. Electromagnetic waves are those fluctuations that have no mechanism to progress whereas mechanical waves demand a mechanism for their communication. Electromagnetic waves progress in a vacuum whereas mechanical waves don't have.

Im 4 and my sis is 13. SHE told me she was on her period but then I told her there was this thing called subject and predicate and how she isnt supposed to have a period at the end of her statement because it wouldnt make any sense... and ya, it didnt go well cause' she put on a tantrum.
But the weird thing is that Google said this "Tantrums are most common between the ages of one and four, then decrease when children start school." SO HOW COME I DIDN"T HABE A TANTRUM!! life makes no sense.

States of matter:There are three states of matter which are;
SolidLiquidGasParticle motion in the states of matter:The degree of motion of particles in the three states of matter differs. The particles of matter in a solid are compacted hence a solid has no space between particles. Particles are less compacted in the liquid phase but are very free in the gas phase.
Hence, model 1 must be the correct representation of a liquid.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformation are taking place?
choices:
Chemical>light>electrical
Mechanical>sound>light
Thermal>solar>electrical
Electrical>thermal>light
Answer:
Electrical>thermal>light
Explanation:
Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.
Thermal energy on the other hand refers to internal energy of a system where temperature is constant.
Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.
Therefore, the energy transformation taking place according to the question is option D.

O animal; 3X salt solution
O plant; pure water
O animal; pure water
O plant; 3X salt solution
Answer:
Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
Plamolysis does not occur in animal cells. Pure water does not produce plasmolysis.Your professor describes an aquatic eukaryote that is single-celled, a primary producer, unable to swim on its own, and is structurally resistant. What organism is most similar to the one described by your professor?

The tropical rain forest biome has some of the highest biodiversity on earth how would a decrease in the biodiversity due to deforestation or other factors affect the large biosphere
Answer:
Negatively.
Explanation:
A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
The decrease in biodiversity due to deforestation and other factors in the tropical rainforest biome will negatively affect the biosphere. Thus, the effect will be negative.
What is the biosphere?The biosphere also called the ecosphere is the sum of the total life or the ecosystem. It includes the part of the planet where life is inhabitants. It may include a mountain, roots, dessert, oceans, etc. It is interrelated to biodiversity.
If the biodiversity of a place gets declined due to factors like deforestation, pollution, poaching, natural disasters, etc. then it will affect the ecosystem. If the stone species are lost then it will have a detrimental effect on the ecosystem.
These negative consequences disrupt the food chain and will result in affecting every organism. This chain of disruption will cause an overall loss to the biosphere.
