Answer:
The statements that describe how the trans bilayer asymmetry in the lipid bilayer is achieved and maintained are listed below.
Explanation:
Phospholipids in the plasma membrane are anchored to a specific location in the plasma membrane via strong hydrophobic interactions with neighbouring lipids thus maintaining the asymmetrical distribution of lipids in the bilayer.
Specific phospholipids in the plasma membrane covalently attach to certain integral membrane proteins.These covalent interaction anchor the phospholipid to specific location in the plasma membrane and maintain the asymmetrical distribution of lipids in the bilayer.
I don’t know about the others, but the first blank is asexual reproduction
Answer: exocrine glands
Explanation: Exocrine gland secrete substances to an epithelial surface through a channel.
The sebaceous and sweat glands associated with the skin also secrete substance to skin surfaces via ducts/ channels and are classified as endocrine gland. There are two glands in the human body Exocrine gland and Endocrine gland.
Endocrine gland secrete substance into the bloodstream directly. Examples of exocrine glands are sweat, salivary, mammary, sebaceous, and mucous.
liver and pancreas are both exocrine and endocrine glands simultaneously.
As exocrine gland, the liver secrete bile and the pancrease secrete pancreatic juice into the gastrointestinal tract through channels. While as endocrine gland they secrete other substances directly into the bloodstream.
