They have limited access to nutrients. <span />
Answer:
1, 2, and 5
Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.
Desmosomes
Desmosomes are cell junction that acts as anchors and distributes tension through a cellular sheet and reduces the chance of tearing when it is subjected to great mechanical stress.
Desmosomes are cell structure by which two adjacent cells are joined. Desmosomes are specialized for cell to cell contact and strong adhesion. The inactiveness of desmosomes can lead to diseases of the skin and heart. Desmosomes are found in tissue that undergo high mechanical stress, such as bladder tissue, epithelial, and cardiac muscle tissue.
That will allow materials into via a passive transport Mechanism and as water and solute movement
Answer:
The cell membrane is decribe by sandwich model and by fluid mosaic model.
Explanation:fluid mosaic model is used to describe the kinds of protein which are present in cell or plasma membrane ...according to this the cell membrane contain intransic,extrinsic,and conjugate molecule like glycoprotien,glycolipid etc.
