pore is always open just the water doesn't flow through it !
Waste exits the paramecium through a structure called the anal pore, located at the posterior end of the cell. This pore allows for the expulsion of unwanted materials and maintains the cell's internal environment.
Leaves will exert a stronger pull from an open pore because water vapor from the leaf can freely diffuse out through an open pore, creating a gradient that pulls more water up through the plant. Closed pores limit this transpiration process.
Thepneumostome (or breathing pore) is a feature (the respiratory opening) of the external body anatomy of an air-breathing land slug or land snail. It is a part of respiratory system of gastropods.
b/c you'll open the pore's and spread the acne
Engaging in toe-sucking can pose health risks, as feet can carry bacteria and fungus. If both partners are comfortable with it and practice good hygiene, it may not pose a significant risk. However, it's best to communicate openly, establish boundaries, and consider any potential health concerns before engaging in this activity.
I have a pore on my face.
The volume of open pore spaces in a rock is known as its porosity. It represents the percentage of void space in the rock that can potentially hold fluids like water or oil. Porosity is an important characteristic in determining the suitability of a rock for storing or transmitting fluids.
Function of Anal-pore
A flatworm has both a mouth pore for ingesting food and an anal pore for excreting waste.
Pore space is the volume of open space between soil particles where air and water can infiltrate and be stored. It affects soil properties by influencing water infiltration, retention, drainage, and aeration, as well as providing habitat for soil organisms and roots. Soil with more pore space typically has better fertility, structure, and drainage properties compared to compacted soils with limited pore space.
Those pores are on the bottom of the leaf surface and are called stomata (singular stoma). They have guard cells that open and close the pore based on several conditions in the environment.
