That tree is hollow. Do you have a hollow leg? I'm going to hollow out a hole.
Your response rings hollow.
His ardent plea rang hollow.
Mosses do not have tubes for moving nutrients and water. They also do not have any true leaves, stems, or roots. Nonvascular plants also do not have transport tubes.
A conical tube is a hollow triangular shaped receptacle often used in laboratories. Conical tubes are used in centrifuges where specimens are spun at high speeds to separate the particles they are made of.
Hollow tubes are cylindrical structures that have empty spaces or cavities inside them. They are commonly used in various applications, such as piping, structural support, and biological systems. Examples include straws, blood vessels, and plumbing pipes.
Hollow tubes are used instead of solid steel tubes to reduce weight while maintaining structural strength. This makes them more cost-effective and efficient for various applications, such as construction, automotive and aerospace industries. Additionally, hollow tubes allow for easier passage of fluids, wires, or other elements through the center.
Microfilaments are thinner rods of protein that enable movement. Microtubules are hollow tubes that give rigidity and shape. Flagella and cilia have microtubules in their centers.
A capillary is hollow. It is the smallest of the blood vessels, the tubes that carry blood.
Well, darling, an IPS tube is a hollow cylindrical structure used for various applications, while an ACSR conductor is a type of electrical cable made up of aluminum strands wrapped around a steel core. So, in simple terms, one is a tube and the other is a conductor - apples and oranges, honey.
Stalagmites can have hollow centers formed due to various processes such as erosion, air pockets, or the flow of water dissolving the interior material. However, not all stalagmites have hollow centers, as some may be solid all the way through depending on the specific conditions of their formation.

First lower the bridge to the lowest it can go (0meters). Then make sure you use all carbon steel. Try and use hollow tubes instead of solid steel. If possible check and see if you can use strong hollow tubes instead of weak solid steal... (ex. use 200mX200m hollow tubes instead of 100mX100m solid tubes) This is sometimes cheaper, not always though. Also once you have your bridge built and it works, look for simple ways to lower the cost, like lowering the strength of some steel beams or hollow tubes.
Yes xylem cells are hollow because Xylem are just made up from cell walls left from cells, making hollow tubes. The walls of these tubes are hydrophilic, so water attaches readily to them, helping it to climb on its way up the plant
