Answer:
urine, nails, hair
Explanation:
Hair - Is a special matrix for the retrospective investigation of chronic drug abuse or poisoning in criminal cases and allows to demonstrate with sensitive methods even a single administration in low amount.
Urine - Is a preferred sample as it is easy to procure for forensic findings. Drugs and drug metabolites can be the target chemicals for the findings of the forensic explorations in different modes of deaths.
Nails - Using keratinized samples has several advantages over methodologies employing body fluids. Long term exposures to different drugs result in the accumulation of the same in these structures. Nails have been shown to accumulate drugs following a long duration of drug intake. Finger and toenails can accumulate drugs during long term exposure
Answer:
Options B and D
Explanation:
In animals, gaseous exchange takes place in the alveoli in the lungs. Generally, animals breath-out (exhale) carbon dioxide and breath-in (inhale) oxygen. Thus, carbon moves from the blood in the form of carbon dioxide into the alveoli in the lungs while the oxygen inhaled moves from the alveoli in the lungs to the blood where it is transported round the body as oxyhaemoglobin.
When the blood gets to the capillaries it feeds the whole body nutrients and holds back waste materials so it isn't spread through our body.
Canned fruit packed in juice is more healthy than the one packed in sugar syrup.
Explanation:
Fruits like apples, peaches, pineapples etc are peeled, cut and stored in cans which are filled either with sugar syrups or their own fruit juices. Sugar syrups are either made heavy or light depending upon their dilution with water.
The main advantage of taking fruits canned in juice rather than in the sugar syrups is the difference in the overall calorie content. The sugar syrups increase the calorie content from around 85 – 200 calories depending upon its strength.
Fruits like peaches are cut and stored in cans filled with their own juice diluted with water. The can usually contain about half a cup of juice and still will increase calories marginally only, like around 60 calories.
So based on the calorie content, it is healthier to take fruits canned in their juices.
