A liquid is rightly modeled by the diagram in model 1.
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.

what is a cell membrane
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.
Explanation:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions
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.
Explanation:
Cell membrane, also called plasma membrane, thin membrane that surrounds every living cell, delimiting the cell from the environment around it.
How is the blackjack seed suited to its method of dispersal?

Explanation:
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.
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.

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.
