What is the relationship between the root of the lung and the hilum?
The root of the lung is connected to the hilum, which is a region where blood vessels, nerves, and bronchi enter and exit the lung. The root of the lung serves as a pathway for these structures to enter and leave the lung.
Is cell wall an impermeable membrane?
No, the cell wall is easily permeable and allows most substances to enter or leave without any resistance
What are the fibers that enter and leave the sympathetic chain without synapsing form structures are called?
They are called splanchnic nerves. These nerves carry preganglionic fibers to the collateral ganglia where they synapse with postganglionic neurons.
Why is it important for the cell membrane to allow materials to enter and leave the cell?
The cell membrane functions as a barrier to protect the cell's internal environment, but it also needs to allow essential nutrients and molecules to enter the cell for survival. Likewise, waste and other materials need to be able to leave the cell to maintain proper cellular function and prevent buildup of harmful substances. This balance of permeability is crucial for the cell's overall health and function.
What do living cell maintain by controlling materials that enter and leave?
Living cells maintain internal conditions necessary for survival by controlling the materials that enter and leave the cell. This process, known as cellular homeostasis, helps regulate the concentration of nutrients, ions, and waste products inside the cell to ensure proper functioning and overall health.
What are the specialized structures that allow gas to enter and leave a leaf?
Stomata.
Specialized structures that allows gas to enter and leave the leaf?
Stomata are specialized structures on the surface of leaves that regulate the entry and exit of gases, such as carbon dioxide and oxygen. These small pores open to allow gas exchange for photosynthesis and close to prevent excess water loss through transpiration.
What is the specialized structure that allows gas to enter and leave the leaf?
Stomatal pores
What structures enter or leave through the hilum of the kidney?
Blood vessels, nerves, lymphatic vessels, and the ureter enter and leave through the hilum of the kidney.
What structures neither enter nor leave the porta hepatis?
Hepatic vein
What are like fences that allow materials to enter and leave a cell?
cell membranes
Does a cell wall allow oxygen and nutrients to enter and waste products to leave?
Yes it does
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane
What molecule movement is when glucose leave your blood streem and enter your cells by attaching to specialized carrier proteins?
Facillitated diffusion
How tides are helpful to sailors?
the rise in water level allow big ships to enter or leave harbors safely.
What did Cerberus eat?
Cerberus' heads are said to have an appetite only for live meat and thus allow the spirits of the dead to freely enter the underworld, but allow none to leave.
Where does all of the molecules enter and leave during Plant respiration?
There are pores on the underside of the leaf called stomata they allow transpiration.
