The section called Breaking Substitution Ciphers (p. 166) describes a "random substitution cipher," in which each letter of the

alphabet is randomly replaced with a different letter or character i.e. A→T, B→F… What makes a random substitution cipher more secure than a Caesar shift?

Answer: Compared to a Caesar shift, the random substitution cipher offers many more possibilities, because the encryption is randomly chosen.

Explanation:

A Caesar Cipher is also a type of substitution cipher, but instead of doing it randomly, it shifts the alphabet by a certain number of characters. Therefore, the answer to decrypt the message is simply to figure out that number.

Fed [463]

Hiya!


<u>Answer:</u>

Of the options given, your answer is A.) As long as you use it responsibly, it will enhance your slides and engage your audience.

<u>Why is this correct?</u>

While Aubrey may not enjoy using media, a visual aid is sometimes needed outside of text. Even if it's sometimes a graphic or a chart, it does wonders to  help it make sense; especially with a mixed bag of people and I'd suggest you google it yourself as well. This means B is out. Sayonara!

Secondly, there MUST be a balance between media and text. Too many images will, as Aubrey believes, have an adverse effect on the presentation. So much as a caption on your photos is good. C is tonight's big loser.

Finally, there is the split between A and D. What do we do now? Both make some lick of sense, right? Think again. Media may help entertain your audience, but that's not the point of presentations most of the time; It's to present information in both a graphical/verbal format without using a video. In fact, I'd say it's harder for a presenter to describe a photo on his own, meaning it will NOT take pressure off the presenter.


I hope my answer helped!

How are water resources and air adversely affected by environmental degardation?​
Nonamiya [84]

Answer:

Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives, and needs".[4] Environmental degradation comes in many types. When natural habitats are destroyed or natural resources are depleted, the environment is degraded. Efforts to counteract this problem include environmental protection and environmental resources management.

There are many examples of environmental degradation throughout the world. A recent example is the 2019 Amazon rainforest wildfires. The Amazon makes up 60% of all rainforests. It is the earth's lungs and with it getting destroyed is posing a huge threat to the environment and the whole world. The effects of the deforestation will pose major impacts on the world around us. The constant cutting down of trees is getting rid of our oxygen supply as well as the absorption of co2. With the continuation of deforestation we will have less available oxygen in the world which could have detrimental effects on human health. An alternate issue that results from this is the overconsumption and waste of the paper products that come from those trees. The waste it typically produces does not get recycled, therefore, immense amount of waste is created. An additional harmful result from this is the degradation of the soil. The constant deforestation causes the soil to become less nutrient which will make it harder to be used again.
