Answer:
c. Proteins and lipids are made on the ER membrane and put in vesicles.
a. Vesicles containing proteins and lipids fuse with the Golgi bodies.
d. The Golgi bodies tag the molecules to signal their ultimate delivery.
b. Vesicles pinched off from the cristernae carry the molecule to its location.
Explanation:
Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
<u>Answer:</u>
Point mutations occur when only one nucleotide is altered affecting only one location or point of the DNA strand.
While Frameshift mutations are caused by the deletion or insertion of a number of nucleotides.
These altered nucleotides affect the triple nature of gene expression disturbing the whole reading frame. All the codons after mutation are different translating a completely different protein. That's why frameshift mutations cause more problems than point mutations.
About 25 of the 92 natural elements are essential to life.

Answer: Option B) is a foreign molecule that evokes a specific response by a lymphocyte
Explanation:
An antigen is a large, foreign molecule (such as a protein) that stimulates the host organism to secrete lymphocytes and specific antibodies that bind to the foreign molecule, labelling it as foreign and destined for destruction.
Thus, option B is the answer
