B) polymerization
Polymer is the plural of monomers basically.
Answer:
<em>An intramolecular force is between that atoms makeup a molecule. An intermolecular force is between entire molecules. A non-polar covalent bond occurs when the electrons are equally shared between atoms.</em>
Answer: Option (c) is the correct answer.
Explanation:
When a system is open then there will be exchange of energy between the system and surrounding.
Whereas when a system is closed then there will be no exchange of energy, that is, thermal energy will not flow into the atmosphere.
Thus, we can conclude that a sealed calorimeter is a closed system because thermal energy is not transferred to the environment.
Answer:
I'm feeling nice today so heres the answer
Explanation:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
Respiration is a process that occurs in the mitochondria.
Diffusion is a passive transport process that does not require energy.
Cellular recognition depends on membrane proteins that act as specific receptors.
