importance of a probe
in hybridization process, molecular biologist label a short fragment of DNA or RNA, usually 10-1000 bases long tagged with a radioactive or fluorescent molecules. this fragment is usually referred to as hybridization probe.probe important both in southern and northern blotting processed because it is used to identify a certain sequence of DNA or RNA in a pool several sequences that have been obtained using nuclease.
process of labeling DNA sequence with a probe
after the DNA strand has been cut into several fragments using enzyme DNA nuclease, the fragments are separated using gel electrophoresis and then denatured using hcl to obtain strands. the single strand are then transferred to nylon membrane that has positive charge. the next step is where probes come in. to detect the DNA sequence of interest the nylon membrane is treated with solution containing tagged probes. since the probes have complementary sequence to the target sequence, it bind to that DNA sequence and detected later using X-ray film.
Answer:
That would be photosynthesis. Glucose and oxygen are rather reactants for cellular respiration

Answer:
PERICARDIUM MEMBRANE
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
Our heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart.
PERICARDIUM FLUID
Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. ... This serous layer has two membranes which enclose the pericardial cavity into which is secreted the pericardial fluid.
The answer is B. A vesicle encloses over a nutrient molecule.
Hope this helps.
