Lipids serve a number of functions in living organisms. which of the following is not a lipid function?
a).body insulation
b).short-term energy storage
c).chemical messenger carrier
d).biological membrane component

The correct answer is B) short-term energy storage.

Explanation:

Glycogen present in the muscles and liver can provide short term energy to the body in the scarcity of glucose. Glycogen is converted into glucose by a process called glycogenolysis and provide instant energy to the body.

Body has more efficiency to store lipids as fat deposits rather than glycogen and lipids provide long term energy source to the body in the absence of glucose like in long fasting. Lipids provide 9 calory energy per gram which is more than twice than energy provided by 1 gm of carbohydrate.

So lipids are used for long term energy storage because it acts as energy reserve and used when no glycogen is left to give energy. Therefore, the correct answer is B) short-term energy storage.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
