1. Centrioles can be correctly matched with F, that is, produce the spindle fibers for cell division.
2. Nucleolus can be correctly matched with G, that is, produce r-RNA to make ribosomes.
3. Nucleus can be correctly matched with B, that is, round structure within the cell.
4. Endoplasmic reticulum can be correctly matched with E, that is, channel through which molecules move in cytoplasm.
5. Golgi bodies can be correctly matched with D, that is, produce and package cell secretions.
6. Ribosomes can be correctly matched with A, that is, tiny structures which synthesize proteins.
7. Chromosomes can be correctly matched with C, that is, contain genes with the information controlling cell.
The lateral and apical meristem.
The correct answer is A. A small dose of the weakened virus is given to the patient so that antibodies can form.
Explanation:
The purpose of a vaccine is to stimulate the immune system of individuals and allow this to create antibodies that can appropriately respond to the virus. This is achieved by creating or producing a weakened or modified version of the virus, then giving this virus to the patient in a low dose that does not make the patient sick but allows his body to produce specific antibodies that can recognize and attack the virus appropriately. In this way, if the patient is in contact with the regular version of the virus its body will generate an appropriate immune response and stop the virus from triggering infection or make the patient sick. In this context, the statement that best describes how a vaccine works is "A small dose of the weakened virus is given to the patient so that antibodies can form".-
The two energy equivalent molecules that contains phosphates
as part of their structure are ATP which is adenosine triphosphate and GTP which
is guanosine triphosphate. Both of these two have three phosphates and two high
energy bonds. In GTP, they are certain to guanosine while in ATP, the phosphate
groups are certain to adenosine.
