Name two hormones produced by the endocrine system and describe how they work with other organ systems to maintain homeostasis
Annette [7]
The 2 hormones are insulin & glucagon.

A hormone will only act on a part of the body it 'fits'. A hormone can be thought of as a key, and its target site ( i.e an organ) has specially shaped locks on the cell walls. 
If the hormone fits, then it will work.

The hormone can set off a cascade of other singling pathways in the cell to cause an immediate effect ( for instance, insulin signaling leads to a rapid uptake of glucose in muscle cells)

The endocrine system is a tightly regulated system that keeps the hormones and their effects at just the right level. One way this is achieved is through ' feedback loops'. The release of hormones is regulated by other hormones, proteins or neuronal signals.

The released hormone then has its effect on other organs. This effect on the organ feeds back to the original signal to control any further hormone release.

Why is copper used to make electric wires?​
sesenic [268]

Question:

Copper is used in a variety of applications, one of which is electrical wires. Whether it’s a power cable for a TV, computer, kitchen appliance or construction tool, it’s probably made of copper. Featuring the atomic number 29, this red-brown metal has become essential to our everyday life by helping power countless devices. But copper isn’t the only material that can transmit electricity, so why is it preferred for creating electrical wires?

Answer:

<h2>The two most important factors on why Copper is used to make not just electric wires, but lots of electric related things is that they are Inexpensive and Super Conductive</h2>

Explanation:

Now, I will explain the reasons why these are good things about the copper wire.

<h2>High Conductivity </h2>

Surpassed only by silver, copper is a highly conductive metal. This means electricity can pass through it with greater ease, making it ideal for use in electrical wires. Companies can use other conductive metals to create electrical wires. Unless they use silver, though, the high conductivity properties of copper allow for a greater distance of electrical current travel. Companies can create longer, better performing electrical wires using copper instead of most other conductive metals.

<h2>Inexpensive </h2>

Copper is also relatively inexpensive when compared to other metals. Gold, for example, is an excellent conductor of electricity, but it costs several times more than copper. If companies used gold to manufacture electrical wires, they’d essentially waste money, as copper is more conductive and costs less than its goal counterpart. This alone is reason enough to make copper the de-facto standard for electrical wires.

<h2>High Ductility </h2>

Copper isn’t just conductive; it’s also ductile. In other words, you can bend and flex copper — to some degree — without it breaking or otherwise sustaining damage. Why is this important? Well, electrical wires must often travel through walls, floors, ceilings and other tight spaces. As a result, they’ll naturally bend and snake their way around the home or building in which they are used. The ductile properties of copper allow copper electrical wires to bend and flex. They’ll still transmit electricity, and they won’t lose any power strength from shape deformity.

<h2>Thermal Resistant </h2>

A benefit of copper electrical wires that’s often overlooked is its thermal-resistant properties. According to ESFI, electrical fires are responsible for more than 51,000 residential house fires in the United States each year — and that’s not accounting for commercial/business fires. Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat.

<h2>As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it’s inexpensive; it’s ductile; and it’s thermal resistant. This makes is the universally accepted standard for the manufacturing of electrical wires.</h2>

What is 5L to mL ( chemistry )
zlopas [31]

There are 1000 mililiters in a liter, so 1000 ml for every liter, you have 5 liters, so:

5L*1000 = 5000 mL

In large generators in power plants, ___________ rotate inside a coil of wire to produce an electric current
lapo4ka [179]
<h3><u>Answer;</u></h3>

Magnets

In large generators in power plants, <u>magnets</u> rotate inside a coil of wire to produce an electric current.

<h3><u>Explanation;</u></h3>
  • Generators are devices that use electromagnetic induction to convert mechanical energy to electrical energy.
  • In power plants, large wheel known as turbine that rotates when pushed by steam,wind, or water and provides mechanical energy to a generator.
  • <u><em>Generators are used in power plants and have very large quantities of copper wire spinning around inside very large magnets, at very high speeds. A turbine spins the shaft that runs the generator. Eventually, electric current is generated.</em></u>
