Answer:
It can be easily exploited by criminals, and it puts our undercover police officers and FBI officers in danger. Also, police officers are already swamped with work and criminal activity as is. It would also be ridiculously hard to get everybody already registered as a resident it the U.S. Take into account the different family types, and how hard it is for single mothers with children.
On the other hand, adding this, despite the obvious hardships, will make catching criminals much easier. Our blood DNA is unique to every human being. It would be extremely helpful to have a system like this in place. This would, at first, be hard to establish, but once it settles in, police officers would be able to spend much more time at home with their families instead of filling out paperwork for overtime.

Answer:
Blood Brain Barrier(BBB)
Explanation:
This is a biological interface of special endothelial cells of astrocytes, pericytes , capillaries, neurons and other structures, acting as a physical barrier or gate separating the Central Nervous system from the peripheral blood circulations. Thus it formed a tight junction serving as a physical barrier to selectively regulate the entrance of substances from the cerebral blood flow into the brain, therefore maintaining homeostasis of the brain.
From above any substances absorbed into the blood stream irrespective of the mode of entry are transported through the BBB, and are selectively regulated to enter the brain cells by the BBB's interactions with the blood vessels, hormones etc.
Basically it allows the passage of nutrients, a few drug, hormones and resists certain toxins and pathogens for the brain homeostasis.
Divergent plates move from each other. This causes to form as well as mid- ocean ridges
Answer: Cyanobacteria, oxygen
Cyanobacteria also known as Cynophyta and blue green algae. It is a phyllum of bacteria that produces it's own food like plants by the process of photosynthesis. It is found in freshwater lakes, damp soils, oceans, moistened rocks and even in animal fur. The purple sulfur bacteria belongs to the group of Proteobacteria. It is an anaerobic bacteria. It is found in hot springs, and stagnant water. It is a photosynthesizing bacterial strain like Cyanobacteria but it does not utilize water to be reduced in the photosynthesis process like in Cynobacteria, to produce oxygen.
Hence, only the <u>Cyanobacteria</u> are capable of releasing <u>oxygen</u>.
