Answer;
-PET scan
A PET scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x-ray
Explanation;
-A positron emission tomography (PET) scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.
-A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.
-In a PET scan, a machine detects radiation that is emitted by a radiotracer. A radiotracer consists of radioactive material that is tagged to a natural chemical, such as glucose.
Answer:
Bacteria
Explanation:
Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.
Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost.
Thus, the correct answer is option (1).
Answer: The correct answer is cortex
Explanation:
The glomerulus and the bowman’s capsule are both located in the Cortex, one of the two main regions of the kidney, alongside the Medulla.
The glomerulus is a mass of blood capillaries linked to urinary tubule, while the Bowman's capsule is a cup-shaped structure. The glomerulus filters materials such water, urea, glucose ET into the bowman's capsule in a process called ultrafiltration, a necessary step in urine formation.
Answer:
C. the cells in these 2 areas have different functions
Answer:
Nucleus
Explanation:
Prokaryotes are the singled cell organisms that do not have a true nucleus which means like eukaryotes they lack a membrane-bound nucleus. So the genetic material of prokaryote are present in the cytoplasm of their cell.
Apart from the nucleus prokaryotes also lack membrane-bound organelle like mitochondria or chloroplast which are present in eukaryotes and helps in ATP formation for the cell. So prokaryotes use the plasma membrane of cell for production of ATP.
Therefore an organism can be classified as a prokaryote if it lacks a nucleus and other membrane-bound organelles.
