How does sneezing and coughing protect the body from viruses?
They help to expel the viruses caught in the respiratory mucus.
What does expel mean in science term?
In scientific terms, "expel" refers to the process of forcefully removing or discharging something from a system or organism. This can occur in various contexts, such as the expulsion of gases from a chemical reaction, the elimination of waste products from biological processes, or the ejection of particles in physical phenomena. Essentially, it denotes the action of pushing something out of a particular environment.
What causes the sound of a fart?
as you expel air from your rectum the air reverberates through your sphincter causing the sound. This sound can be further amplified by the air reverberating your butt cheeks :)
Why do clam sqirt water?
Clams suck in and expel water through their siphon tubes to filter food particles out of the water, to breathe (by running the water over gills), and to eliminate waste.
What is the meaning of the word expel?
1. to force something out : 2 : to force to leave (as a place or organization) by official action : take away rights or privileges of membership
What organelle allows free-living protists to expel extra?
The contractile vacuole allows free-living protists to expel extra water
What organelle allows free living protists to expel etra water?
The organelle that allows free-living protists to expel excess water is called the contractile vacuole. This structure collects excess water that enters the protist's body and then contracts to expel it, helping to maintain osmotic balance and prevent the cell from bursting in hypotonic environments. Contractile vacuoles are particularly important in freshwater protists, where water influx is constant.
What organelle allows free living protists to epel extra water?
The organelle that allows free-living protists to expel excess water is called the contractile vacuole. This structure collects excess water that enters the cell and then contracts to expel the water outside, helping to maintain osmotic balance. Contractile vacuoles are particularly important in freshwater protists, which live in environments where water influx can be significant.
What organell allows free living protists to expel extra water?
The contractile vacuole allows free-living protists to expel extra water
What do vacuoles in protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
What do contractile vacuoles protists do?
Contractile vacuoles in protists collect water and then expel it when they become full.
Some protists use energy to expel what from their cytoplasm?
Some protists use energy to expel waste products or excess materials from their cytoplasm through processes like exocytosis. This mechanism allows them to maintain homeostasis and manage cellular waste, which is crucial for their survival. Additionally, some protists may expel toxins or other harmful substances to protect themselves from environmental stressors. Overall, this energy-dependent process is vital for their cellular health and function.
How water balance is maintained in fiesh water protists?
Freshwater protists maintain water balance primarily through osmoregulation, utilizing contractile vacuoles to expel excess water that enters their cells due to osmosis. These organelles collect and release water periodically, preventing the cell from swelling and bursting. Additionally, protists can adjust their internal solute concentrations to help regulate osmotic pressure. This ability allows them to thrive in their aquatic environments despite fluctuations in external conditions.
Where does a protist with contractile vacuoles live?
Contractile vacuoles in protists collect water and then expel it when they become full.
What do protists use to regulate water?
Protists use contractile vacuoles to regulate water and maintain osmotic balance. These vacuoles collect excess water that enters the cell and expel it through a process of contraction. This mechanism is especially important for freshwater protists, which are constantly gaining water due to the lower concentration of solutes in their environment compared to their cytoplasm. By effectively managing water levels, protists can prevent cell lysis and maintain homeostasis.
How does paremecium expel water?
Paramecium expels excess water through a specialized structure called the contractile vacuole. This organelle collects excess water that enters the cell through osmosis, and when it reaches a certain size, it contracts to expel the water out of the cell through a pore in the membrane. This process is crucial for maintaining osmotic balance and preventing the cell from bursting in a hypotonic environment.
How many syllables in expel?
Expel has two syllables.
