what layers of protection can be used tot detect and respond to abnormal reactions or process conditions

1 answer:

5 0

In the body, the main protective layer is known as the epithelium, this can be found in the skin as well as other organs such as the lungs.

The body is often exposed to external factors that can damage it; due to this, throughout evolution, most animals and multicellular organisms have developed protective mechanisms.

In the case of humans and other animals, the protective layer is known as the epithelium, which is composed of epithelial cells. This protective layer can be found internally and externally.

External layer: This is the first protective layer, commonly known as skin, this layer protects the inner organs from extreme temperatures, changes in pressure, etc.

Internal layer: Organs such as the lungs or the ones in the gastrointestinal system are all covered by a thin epithelial layer that helps each organ to be protected.

Which is least likely to be reduced? A. Zn^2+ B. Fe^3+ C. Cu^2+ D. Fe^2+

alekssr [168]

A. Zn²⁺

<h3>Further explanation</h3>

Given

Cations of several elements

Required

The least to be reduced

Solution

If we look at the voltaic series:

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe²⁺-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Fe³⁺-Ag-Pt-Au

The electrode which is easier to reduce than the hydrogen (H2) electrode has a positive sign (E red= +) and is located to the right of the voltaic series (right of H)

The electrode which is easier to oxidize than the hydrogen (H2) electrode and is difficult to experience reduction has a negative sign (E red= -) and is located to the left of the voltaic series (left of H)

Or you can look at the standard reduction potential value of the metals in the answer options, and the most negative reduction E° value which will be difficult to reduce.

The Zn metal is located far left of the other metals in the answer choices, so it is the most difficult to reduce

How does nuclear energy generate electricity? Please help!

svet-max [94.6K]

A clean energy resource. Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plantsdo not burn fuel, they do not produce greenhouse gas emissions. I hope that this helps you out, have an amazing day!!

Which formula shows a correct representation of the combined gas law?(1 point)

Svetlanka [38]

The formula that shows the correct representation of the combined gas law is; V1P1 / T1=V2P2 / T2

The combined gas law is obtained from the statements of Charles law and Boyle's law as follows;

Charles law; V/T = k

Boyle's law = PV = k

Combining the two I have; PV/T = k

For two masses of an ideal gas;

V1P1 / T1=V2P2 / T2

This is the statement of the combined gas law.
