A bright light shines into Aubree's eyes. Which organ system will the nervous system alert in order to allow less light into her
MrRissso [65]

The nervous system alert in order to shrink of eye is musculoskeletal system.

<h3>What is musculoskeletal system?</h3>

The musculoskeletal system is an essential component of human health. The musculoskeletal system provides form, stability, and movement to the human body.

In addition to providing the body with structure and the means for movement, the musculoskeletal system acts as an endocrine system, stimulated by exercise, interacting through biochemical signaling with other organs in the body.

While at the zoo you see an exhibit with a small group of primates and notice they have wet, snout-like noses, grooming claws, a
Gemiola [76]

Answer:

a species of strepsirhini that retain a rhinarium found only in prosimian primates.  

Explanation:

Many species are found in the wild. Strepsirhini is a species found in the jungle. Rihinarium is related to the shape of the nose. This is the area where fur is not presented and nostrils external opening found in the animals and many mammals. This is the area that makes moisture in many species. Cat and lion-like species come under this category. Sometimes it is called a wet nose and wet snout. The study f these mammals sometimes expose the evolution and taxonomy in these species.  

So that when you see a small group of primates in the zoo, they have wet nose or snouts are species of strepsirhini.

Which heuristic involves forming predictions based on the ease with which a situation can be imagined?
Alik [6]

Anchoring-and-adjustment heuristic involves forming predictions based on the ease with which a situation can be imagined.

Any strategy for problem solving or self-discovery that uses a practical method that is not ensured to be optimal, perfect, or rational but is nevertheless sufficient for achieving an immediate, short-term goal or approximation is referred to as a heuristic. Heuristics can be viewed as generic cognitive frameworks that people frequently use to arrive at solutions rapidly.

A person uses the cognitive heuristic of "anchoring and adjustment," whereby they begin with a basic notion and then modify their views in light of this notion. When the original anchor deviates from the genuine value, it has been demonstrated that anchoring and adjustment would yield incorrect results.

Nitrogen and hydrogen gases are related in a 1:3 mole ratio at 700 K. Calculate the total
In-s [12.5K]

A brief summary of the Haber Process

The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic.

A flow scheme for the Haber Process looks like this:

Some notes on the conditions

The catalyst

The catalyst is actually slightly more complicated than pure iron. It has potassium hydroxide added to it as a promoter - a substance that increases its efficiency.

The pressure

The pressure varies from one manufacturing plant to another, but is always high. You can't go far wrong in an exam quoting 200 atmospheres.

Recycling

At each pass of the gases through the reactor, only about 15% of the nitrogen and hydrogen converts to ammonia. (This figure also varies from plant to plant.) By continual recycling of the unreacted nitrogen and hydrogen, the overall conversion is about 98%.

Explaining the conditions

The proportions of nitrogen and hydrogen

The mixture of nitrogen and hydrogen going into the reactor is in the ratio of 1 volume of nitrogen to 3 volumes of hydrogen.

Avogadro's Law says that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. That means that the gases are going into the reactor in the ratio of 1 molecule of nitrogen to 3 of hydrogen.

That is the proportion demanded by the equation.

In some reactions you might choose to use an excess of one of the reactants. You would do this if it is particularly important to use up as much as possible of the other reactant - if, for example, it was much more expensive. That doesn't apply in this case.

There is always a down-side to using anything other than the equation proportions. If you have an excess of one reactant there will be molecules passing through the reactor which can't possibly react because there isn't anything for them to react with. This wastes reactor space - particularly space on the surface of the catalyst.

The temperature

Equilibrium considerations

You need to shift the position of the equilibrium as far as possible to the right in order to produce the maximum possible amount of ammonia in the equilibrium mixture.

The forward reaction (the production of ammonia) is exothermic.

According to Le Chatelier's Principle, this will be favoured if you lower the temperature. The system will respond by moving the position of equilibrium to counteract this - in other words by producing more heat.

In order to get as much ammonia as possible in the equilibrium mixture, you need as low a temperature as possible. However, 400 - 450°C isn't a low temperature!

Rate considerations

The lower the temperature you use, the slower the reaction becomes. A manufacturer is trying to produce as much ammonia as possible per day. It makes no sense to try to achieve an equilibrium mixture which contains a very high proportion of ammonia if it takes several years for the reaction to reach that equilibrium.

You need the gases to reach equilibrium within the very short time that they will be in contact with the catalyst in the reactor.

The compromise

400 - 450°C is a compromise temperature producing a reasonably high proportion of ammonia in the equilibrium mixture (even if it is only 15%), but in a very short time.

The pressure

Equilibrium considerations

Notice that there are 4 molecules on the left-hand side of the equation, but only 2 on the right.

According to Le Chatelier's Principle, if you increase the pressure the system will respond by favouring the reaction which produces fewer molecules. That will cause the pressure to fall again.

In order to get as much ammonia as possible in the equilibrium mixture, you need as high a pressure as possible. 200 atmospheres is a high pressure, but not amazingly high.

Rate considerations

Increasing the pressure brings the molecules closer together. In this particular instance, it will increase their chances of hitting and sticking to the surface of the catalyst where they can react. The higher the pressure the better in terms of the rate of a gas reaction.

Economic considerations

Very high pressures are very expensive to produce on two counts.

You have to build extremely strong pipes and containment vessels to withstand the very high pressure. That increases your capital costs when the plant is built.

High pressures cost a lot to produce and maintain. That means that the running costs of your plant are very high.

The compromise

200 atmospheres is a compromise pressure chosen on economic grounds. If the pressure used is too high, the cost of generating it exceeds the price you can get for the extra ammonia produced.

What do you understand by human poverty
solmaris [256]

Answer: Human Poverty happens when people does not have the basic conditions to guarantee its survival with quality of life and dignity. Poverty also often refers to the social and economic class of people who are poor.

Poverty can be characterized as covering different aspects of individuals' lives, such as the lack of essential goods and services for life: food, clothing, health care, housing.

Social deprivation is also one of the main characteristics of poverty, namely the inability of people to participate equally in society.
