Answer:
This is because of the presence of a lot of sugar in the diabetic patient's blood stream.
Explanation:
As a test for the presence of simple sugars, Benedict's solution is usually added to the test sample and then heated.
A diabetic patient's body system has a lot of sugar flowing around in the blood stream. His body is unable to get this sugar into the cells for use, because the insulin produced by his pancreas is not enough. As a result his body system has a lot of sugar.
Consequently, whenever the patient urinates, the urine has a high sugar content as opposed to a normal person, whose urine has a low sugar content because of a normal functioning body system.
The high sugar content of the diabetic patient's urine is what gives an intense brick red precipitation with Benedict's reagent.
Answer:
Ozone is formed in the stratosphere naturally.
High energy solar radiation strike the oxygen atoms O2, the two atoms split apart. The freed atom collides with another oxygen atom O2 forming O3 (Ozone)
Ozone layer is destroyed when chloroflourocarbons and halons.
CFCs and halons cause chemical reactions that break down ozone molecules. Consequences ofnozone depletion are that UV radiations are not filtered and they reach the earth causing damage to eyes and skin.
Explanation:
Ozone layer is a protective layer which protects from UV damaging radiations. It is formed when oxygen atoms are broken down by photolysis and a freed oxygen atom combines with another amd form O3.
Ozone is being depleted now because chlorofluorocarbons (CFCs) and halons—gases found in aerosol spray cans and refrigerants—are released into the atmosphere they decrease the ozone's ultraviolet radiation-absorbing capacity.Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include skin cancers, eye cataracts and immune deficiency disorders.
Answer:
Carbohydrates- these are food stuffs with sugar and fibers that provide energy to the body.
Fibres- these are things obtained from plants or animals.

Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
