Cells assemble carbohydrates through dehydration synthesis which means a(n) what molecule is removed when the monomers are bonde
mr_godi [17]
The process for connecting two monomers together is called dehydration synthesis. Dehydration means “removal of water” and synthesis means “to join together”. So in this process, two monomers are covalently bonded by the removal of a water molecule. Each organic monomer has a hydroxyl group on one side and a hydrogen on the other. When two monomers line up side by side, they will have these two functional groups facing one another. The H and the OH will break off of their respective monomers and bond forming a water molecule. This is the dehydration part of the process. Each monomer now has a carbon atom that needs to covalently bond with something, so they bind to each other forming a polymer. That is the synthesis part of the process.

Which of the following is NOT an example of a selection pressure?
Lena [83]

Answer:

B. Surgery

Explanation:

I am not entirely sure but based on the definition of selection pressure (which talks about how external agents affect the survival of an organism) surgery is does not meet the definition.

A tiger hunting a prey affects the survival of prey. Beginning of ice age is an environmental agent that can affect survival of organism that cant tolerate cold. Antibiotics are drugs that can kill bacteria thus lower their survival. Surgery can actually increase survival if some form of disease is being treated.
