Answer 2

Answer:

A language is context-free if it is generated by a CFG. For compactness, we write S → 0S1 | ε where the vertical bar means or. Let P be language of palindromes with alpha- bet {a,b}. One can determine a CFG for P by finding a recursive decomposition.

Now, open the Notebook tool () and brainstorm ideas for this topic. Ask yourself the following questions:

What is the purpose of recycling?
What are the benefits of recycling?
What, if any, negative effects does recycling have?

You did some brainstorming for the debate topic “Should recycling be required?” Write three one-sentence propositional arguments on the topic. Then write three oppositional arguments.

Answers

Answer:

What is the purpose of recycling?

The purpose of recycling is to reuse old things to prevent additional trash going into wastelands/beaches/where ever they end up.

What are the benefits of recycling?

When companies use old products (recycling them), it reduces the amount of new products needing to be made. So, rather than using a tree to make paper, they would use old consumer's paper instead.

What, if any, negative effects does recycling have?

I personally can't think of any negative effects.It's not even that out of the way of day to day life. If something's going in the bin, you might as well put it in a recycling bin (if it's recycle safe).

Should recycling be required?

Yes. I do believe recycling should be required. It will help minimize trash in the environment reusing the blastic bottles, paper or whatever instead of feeding it to the turtles. It's not too far out of the way either. As mentioned above, it can be incorperated into day to day life. By recycling, we are opening up new job positions that will protect the environment.

However, recycling can be bad for the "new product" industry because people are using less and less new products each year in favor of eco friendly/recycled material industries.

Okay, I know the question said write three opposing arguments to why recycling should be required, but... I can't think of anything else. Good luck with your assignment and let me know if you've got questions about my answer.

Los tejidos son capas de células similares que cumplen con una función específica. Los diferentes tipos de tejidos se agrupan para formar órganos.
Hay cuatro tipos básicos de tejido: tejido conectivo, tejido epitelial, tejido muscular y tejido nervioso. El tejido conectivo sostiene y une otros tejidos como el óseo, el sanguíneo y el linfático. El tejido epitelial sirve de cobertura; entre éstos se encuentran la piel y el revestimiento de varios conductos en el interior del cuerpo. El tejido muscular consta de músculos estriados o voluntarios que mueven el esqueleto y de músculo liso, tal como el que rodea al estómago. El tejido nervioso está formado por células nerviosas o neuronas y sirve para llevar "mensajes" hacia y desde varias partes del cuerpo.
