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).
Answer: D. Begin assisting her ventilations with a bag-mask device and assess her pulse rate.
Explanation: In pediatric care
A Bag-valve-mask (BVM) device is a portable resuscitator. In pediatric care, when a patient is having trouble breathing, it is of utmost importance that the clinician first establishes an airway. A BVM with hundred percent oxygen should be used during the wait before intubation.
Once this has been done, the next priority is to monitor the pulse of the child. This can be through the done by a pulse oximeter or ensuring chest motions are synchronized with breathing sounds.
All muscle cells share four main properties that distinguish them from other cells. These are Excitability, Contractility, Extensibility and Elasticity.

Answer:
<em>Ask the friend to think about the repercussions of keeping it secret.</em>
Explanation:
When someone remains silent about their intrusive thoughts or excruciating behavior towards them-self, it is a very serious topic as the person may be on the brink of playing into the thoughts. There are reasons behind why the others are wrongful acts.
"<u>Tell the friend you understand and you would never betray him."</u>
This is simply the worst option to choose because it is not helping your friend nor it is helping yourself. You're allowing your friend to continue to hide their emotional pain which could possibly lead to a dead end.
<u>"Ask the friend why he or she wants to keep it a secret."</u>
As this is a semi-acceptable answer, it just isn't what you should do at the time being. See, it allows your friend to talk about why they're so secretive about it, but it doesn't do any good. As many of us want to help our friends through their tough times, this friend is at a point where there needs to be some sort of action.
<u>"Tell the friend they can't keep a secret about something so serious."</u>
This is a bad tactic to helping your friend. You are both losing their trust and you're allowing the friend to try to figure out how to get around the situation. The friend could go and act on their intrusive thoughts then and there to avoid confrontation. As hard as it is to hear that a friend is going through this, you have be somewhat reasonable in your decisions.
