Answer: The particles that can pass through the cell membrane are the GREEN SOLVENT PARTICLES.
Explanation:
OSMOSIS can be defined as the thermal movement of solvent (water molecules) through a selectively permeable or semi-permeable membrane from a region of high concentration of the solvent to one where they are in low concentration.
The cell is bound by a membrane called plasma membrane. This membrane is selectively permeable and allows water and certain dissolved solvents to pass through it. As a result, the plasma membrane of the cell regulates the movement of materials between the cell and it's environment.
From the osmosis gizmo, it portrays a typical example of osmotic reaction occuring between a cell immersed in a solution of purple solute particles dissolved in green solvent particles. In order to maintain an osmotic balance between the cell and the solution surrounding it, the solvent (which is the green solvent particles) will move from the region of higher concentration to a lower region through the cell membrane
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
Answer:
Moth has the best hearing among both animals and humans
Answer:
1.75 billion years
Explanation:
Scientists have concluded that Earth could potentially continue to host life for at LEAST another 1.75 billion years. As long as there's no natural disasters or nuclear wars, we should be good. (Right?)
But, eventually, over time Earth will become uninhabitable. :o
The virulence of the microbes should be high to cause an active infection.
Explanation:
Virulence is the actual potential or ability of a pathogenic microbe to infect a host. Even with a high median infectious dose to cause an infection, it is the virulence which defines the level of pathogenicity or ability of the pathogens like the foodborne pathogens to cause and active infection.
An active infection is caused when virulence of the pathogen is high. The virulence factors are surface receptors, surface coats, and toxins.
Virulent bacteria cause active infection by adhesion, colonization, invasion, immune response inhibitors, or as toxins. A virulent virus replicates rapidly and modifies the host’s defensive mechanism
