Which of the following is NOT a factor that negatively influences teen drug abuse?
deff fn [24]
The answer is strong refusal skills. A teen who has been properly raised would know the difference between right and wrong and has a sense of directions to what he or she wants to do with his or her life. They have the decision to put themselves in that position. No amount of peer pressure would force a strong youth to take drugs when he or she is capable of taking charge of his or her life.

Eating lower on the food chain I. would decrease the energy lost from feeding grains to livestock. II. refers to humans eating m
MrMuchimi

Answer:

All of the above (I, II, III)

Explanation:

Plants (grains) are mostly the organisms found low the food chain, while humans are found at the topmost trophic level on the food chain. Cattle, sheep and goats could be referred to as primary consumers while grains (plants) found at the bottom of the food chain are primary producers. In the food chain, the amount of energy passed from one trophic level to another decreases as only about 10% of energy at a particular trophic level is passed on to the next trophic level.  

When humans who are at the topmost trophic level of a food chain feed on primary producers (plants) instead of primary consumers (cattle, sheep), we refer to this as eating lower on the food chain.

When humans eat lower on the food chain (i.e. rely majorly on plants), more grains and agricultural crops would be available for human consumption as a result of less land and grains that would be required to be fed on by primary consumers (cattle, sheep, goats). For example, 1 hectare of grain crop is used to feed cattle, and the cattle is fed on later by humans. If humans feed on grain crops directly instead of feeding on cattle, the 1 hectare of grain crops can serve almost times two of the human population that initially feed on cattle. Less cattle would be kept as humans feed low on grains, which means, more grains would be available as there would be less cattle that would be reared for human consumption. Also, energy lost would be decreased, as more energy gotten directly from the grains would be more than what humans would get when they feed on primary consumers (cattle) that feed on plants .

  • Eating lower on the food chain, which refers to humans eating more primary producers than primary consumers (II), would decrease the energy lost from feeding grains to livestock (I), and could increase grain and agricultural crops available for human consumption (III).

Based on what you know about the function of the nephron, why should urine be free of blood cells?
baherus [9]
<span>The nephron is the basic structural and functional unit of the kidney, it regulates the concentration of water and soluble substances like sodium through filtering the blood, reabsorbing what is needed and excreting the rest as urine. Therefore urine should be free of blood as the nephron filters the blood, cleaning it for the body to reuse.</span>

ivanzaharov [21]
These nine basic training principles apply to sports training. With regards to location, the training principles that could influence it is the specificity, variation and overload. Specificity refers to the type of exercises you do based on the type of sport you play. Variation is when you do not only focus on one part of your body. Lastly, overload is adding additional stress to your body to achieve progression. These all influence location whether it has amenities that could cater to the type of exercises that you do. Does the location allow you to have a hold of resources for overload? Does the location have different sections that allow your body for variation? Does the place cater to your specific sport?
