Answer:
c. sodium-potassium pump
Explanation:
a. osmosis - this is a type at of passive transport. It is diffusion specific to water molecules.
b. diffusion - this is also a type of passive transport. Molecules move from a high concentration to a low concentration down a concentration gradient. This is passive transport and does not require energy.
c. A sodium-potassium pump is a type of active transport, it uses energy to move ions across the membrane. They cannot pass through the membrane because they are charged.
d, facilitated diffusion is a type of passive transport through which substances are transported through proteins in the plasma membrane.
Answer:
The correct answer is - create polypeptide and eventually proteins for gene expression.
Explanation:
This model is representing the translation process in protein synthesis which takes place in the cytoplasm of the cell and results in forming proteins from the information carried by mRNA from DNA in a code. The translation is the process that translates the code, carried out by mRNA with help of ribosome and tRNA, into a chain of amino acids called polypeptide chain that forms eventually in protein.
1. mRNA strand and ribosome present of ER translate codes into a protein.
2. Amino acids are transferred by the tRNA molecules to the ribosomes.
3. mRNA and tRNA bases are paired and amino acids are left behind to create polypeptide.

Answer:
Terminal end moraine
Explanation:
The easiest way to remember that this is the farthest advance of a glacier is the word "terminal". It very literally means the end. Hope this helps :)
