What else can I help you with?
A material that will not permit the passage of electricity is called what?
It is an insulator.
What is passage of gas through the anus is?
first thats gay
What is the transition word after after that?
There is no way to answer this without more information. A transition word is a word used to connect two parts of a passage or quotation, so to complete your question you need to supply the passage or quotation.
What method of comparison is used in the following passage?
To provide an accurate answer, I need to see the passage you're referring to. Please share the text or key details so I can identify the method of comparison used.
What is the second step when evaluating writing with a general rubric?
Read the passage
Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
Yes, some membranes have protein channels called aquaporins that allow for the passage of hydrophilic substances like water across the membrane. These channels facilitate the movement of water molecules while excluding other substances.
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
Is this true some membranes have proteins with channels or pores that allow for passage of hydrophilic substances?
yes it's true.
What do you call a thin solids that allow certain substances to diffuse through them?
Semi-permeable membranes are thin solids that allow certain substances to diffuse through them while preventing the passage of others.
What supervises substances entering and exiting the cell?
The cell membrane supervises the substances entering and exiting the cell. It is selectively permeable and regulates the passage of molecules in and out of the cell through active or passive transport mechanisms.
Do prokaryotic cells have cell membranes?
Yes, prokaryotic cells have cell membranes. The cell membrane surrounds the entire cell and separates its internal environment from the external environment. It regulates the passage of substances in and out of the cell.
What type of tissue is so thin it is considered primarily with the movement of various substances across the membranes from one body compartment to another?
Epithelial tissue is the type of tissue that is thin and primarily concerned with the movement of substances across membranes. It forms the lining of various organs and cavities in the body, allowing for the selective passage of molecules and ions.
Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
Passage of water through cell membranes?
Osmosis
Are cell membranes in prokaryotic and eukaryotic cells different in structure and function?
Yes, cell membranes in prokaryotic and eukaryotic cells have similar structures but differ in some aspects of their functions. Prokaryotic cell membranes lack membrane-bound organelles, while eukaryotic cell membranes contain them. Both types of cell membranes regulate the passage of substances in and out of the cell, but eukaryotic cell membranes are more complex due to the presence of organelles.
What are the functions that cell membranes perform?
Cell membranes perform several key functions, including acting as a barrier to regulate the passage of substances in and out of the cell, providing structural support to the cell, facilitating cell communication and signaling, and recognizing and binding to specific molecules like hormones or antigens.
The compounds in biological membranes that form a barrier to the movement of hydrophilic materials across the membranes are?
phospholipids and cholesterol are the main compounds that form the barrier to the movement of hydrophilic materials across biological membranes. The hydrophobic tails of the phospholipids create a barrier that prevents the passage of hydrophilic substances. Cholesterol helps maintain the fluidity and stability of the membrane.
