A Pothos is what the plant is called

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.

Answer:

The correct answer is - diatom (protist)

Explanation:

The characteristic described by the professor is most similar to the characteristic of aquatic protist - diatoms. Diatoms are the aquatic protist fall into the eukaryotic type of organisms.

These organisms are single-celled and can not swim on their own. They are a primary producer as they do not depends on others for their food and energy and synthesized themselves.

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.

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.

Explanation:

An equinox is commonly regarded as the instant of time when the plane (extended indefinitely in all directions) of Earth 's equator passes through the center of the Sun. This occurs twice each year: around 20 March and 23 September.

Answer:

An Equinox is commonly regarded as the instant of time when the plane of Earth's equator passes through the geometric center of the Sun's disk. This occurs twice each year, around 20 March and 23 September.  In other words, it is the moment at which the center of the visible Sun is directly above the equator.

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.

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."

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.

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

There are three states of matter which are;

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.
