C.to help programmers debug the code. D.to make coding easier for learners E.to make it easier for machines to read the code

Answers

Answer:

A

Explanation:

It's not the following because:

B- visual appeal doesn't really matter when you're getting a job done in terms of programming

C- auto completion doesn't help with debugging it just ensures there's no syntax errors in the first place

D- it could be this, but seasoned coders also use highlighting and autocompletion so I thought A would be a better fit to encompass all coders

I need help getting earbuds please help

My mom wants reasons to get wireless earbuds and i'm out.

I need someone to give me some good things about wireless earbuds and bad things about wired earbuds.
(and i got in truble with bluetooth headphones)

Answers

Answer:

Wireless earbuds are a lot harder to break.

Explanation:

Normally if something goes wrong with wired earbuds/headphones it's due to the cord. Wired earbuds can break more easily and can possibly break off in the headphone jack (which is not fun to deal with, believe me. I had to deal with it a few weeks ago). Furthermore, wireless earbuds can't get tangled because they don't have a cord. Wired earbuds cords tend to get tangled and it's a pain to fix it every time it happens. Good luck getting your earbuds.

well im going to play devil's advocate here

reasons why you should not get wired earbuds they produce more greenhouse gas not just to make them but they take constant power and Bluetooth so this causes more greenhouse gas

you may think you need to replace them less but when you factor in the outright cost you still pay more

B.These introduced species will require more land to be protected


C.Introduced species often become endangered when they are placed in a new habitat


D.Predators of the zebra mussels will decrease after these organisms are introduced into the habitat

Answers

Answer: A.The introduced species compete for resources more effectively than native species.

Explanation:

An introduced species is also called the exotic species and this is an organism which is not a native organism or specie and therefore isn't native to the place but rather it's being transported to the place through the activities of human being.

When the introduced species are introduced to a particular area, they compete with the natives for the available resources and often do this more effectively than the other native species.
