How does phagolysosome differ from a phagosome?
A phagolysosome is formed when a phagosome containing ingested material fuses with a lysosome to form a digestive compartment filled with enzymes. The phagolysosome facilitates the breakdown of the ingested material. A phagosome, on the other hand, is a vacuole formed by the fusion of a phagocytic cell membrane with the membrane surrounding the engulfed particle or microorganism before it fuses with a lysosome to become a phagolysosome.
What is this process occurs when a cell engulfs large food particles?
Phagocytosis is the process where a cell engulfs large food particles or other cells by wrapping cell membrane around the particle and forming a vesicle called a phagosome. The phagosome then fuses with lysosomes to breakdown the ingested material for nutrient extraction or disposal.
What are two way in which a particle that is too large to fit through the cell membrane can enter the cell?
Particles to large to pass through the cell membrane can ebter by pinocytosis (cell membrane extends to surround a liquid and forms a new vacuole) or phagocytosis (the cytoplasm extends and surrounds the particle to be ingested)
Particle with a large mass and a posiive charge?
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
What is the average speed of the particle?
The average speed of a particle is the total distance traveled divided by the total time taken. This gives you a measure of the overall speed of the particle throughout its journey.

When an amoeba engulfs a particle of food what is formed?
Two pseudopodia are extended with microtubular action and surround the food particle. Instead of reeling the particle in the amoeba pulls itself up to the particle and then it is ingested through the cellular membrane.
What will happen to the wavelength associated with a moving particle if its velocity is reduced to half?
If the velocity of a moving particle is reduced to half, the wavelength associated with it will remain the same. The wavelength of a particle is determined by its momentum, not its velocity.
Is a negatively charged particle the same as a neutral particle?
No, a negatively charged particle (electron) has a negative charge associated with it. A neutral particle (neutron) is neither negatively charged nor positively charged.
What decay has no particle associated with it?
All nuclear decay has some kind of particle or particles associated with it. Even the metastable decay of 4399Tcm, a gamma at 142.7 Kev, is considered to be a particle emission, because a gamma is a photon, and a photon is an elementary particle, per our understanding of modern quantum mechanics and particle physics, even though it has no mass at rest state.
Which of the following is NOT a representative particle?
atom
What is boson particle?
The boson particle is usually associated with the Higgs field. It is an energy field that transmits the mass to the things that travel through it.
Radioactive particle that is harmful to human beings?
Plutonium-239 is a radioactive particle that is harmful to human beings due to its high toxicity and ability to emit high-energy alpha particles, which can damage cells and cause long-term health effects such as cancer and organ failure if ingested or inhaled.
Which of the following is the largest particle in soil?
The largest particle in soil is sand. Sand particles have a diameter between 0.05 to 2 millimeters.
Which matter particle has 34 protons and 36 electrons in the following configuration?
Se
What is meant by the de broglie wavelength of a particle?
The de Broglie wavelength is a concept in quantum mechanics that describes the wave nature of a particle. It represents the wavelength associated with a particle's momentum, showing that particles such as electrons have both wave and particle-like properties. The de Broglie wavelength is inversely proportional to the momentum of the particle.
What are the properties and characteristics of a spin zero particle?
A spin zero particle has no intrinsic angular momentum, meaning it does not spin on its axis. It is scalar in nature, meaning it has no directionality. This type of particle is often associated with the Higgs boson, which was discovered in 2012.
