Explanation:
_______________________________________________________
Essentially, the question is asking:
_______________________________________________________
"Which of the following answer choices are characteristics of "bases", ONLY ? " ;
→ {and NOT TRUE of "acids", only} ; AND:
→ {and NOT TRUE of BOTH: "acids" ; AND: "bases"}? ;
_______________________________________________________
The answer choices, as posted, are:
_______________________________________________________
[A]: <span>conducts electric current ;
[B]: produces OH</span>⁻<span> ions .
[C]: tastes sour ;
[D]: reacts with carbonates.
_______________________________________________________
</span>→ <span>The correct answer is: </span>[B]: "produces OH⁻ ions" .
_______________________________________________________
Note that "bases" (NOT "acids") produce "hydroxide ions" {i.e. "OH⁻ " ions} when dissolved in water; whereas "acids" (NOT "bases") produce "hydrogen ions" {i.e. " H⁺ " ions} when dissolved in water.
_______________________________________________________
Hence, this answer choice: [B]: "produces OH– ions" ;
→ is CORRECT.
_______________________________________________________
Let us consider the other answer choices:
_______________________________________________________
[A]: "conducts electric current" ; is INCORRECT. This characteristic applies to BOTH: "acids" (of various types) ; AND to "bases" (of various types) — and NOT strictly to "bases" .
_______________________________________________________
[C]: "tastes sour" ; is INCORRECT.
This characteristic applies to "acids"— AND NOT to "bases".
Note that "acids" tend to taste "sour", whereas as "bases" tend to taste "chalky".
_______________________________________________________
[D]: "reacts with carbonates" ; is INCORRECT.
Note that "acids" — NOT "bases" — react with carbonates ["carbonates" are "bases"] — to produce a salt and water— and release "CO₂ (g) " — that is, "carbon dioxide" (in gaseous form).
_______________________________________________________
→ The correct answer is:
_______________________________________________________
→ Answer choice: [B]: " produces OH⁻ ions " .

Hope this answer—and rudimentary [yet lengthy] — explanation is of help to you.
Best wishes in your academic pursuits!

It will sink because of how much the max capacity a boat can have it will sink because it is over capacity that’s why it will sink.
Hope this helps :)
Answer:
The magnetic flux is
Explanation:
From the question we are told that
The value of the charge is
The length of each side of the cube is
Generally the magnetic flux through a closed surface is mathematically represented as
Where D is the area enclosing the charge
Now a cube is made up of six faces but in this question we are considering only one face which is mathematically represented as
So the electric flux through one face of the cube is mathematically represented as
where is the permitivity of free space with value
substituting value
Answer:
Roundworms:
The size of roundworms ranges from microscopic to as long as a meter long. Most roundworms have a hard, sharp lance on their head, and some have bristles on the head. Most of the roundworms are protected by an adaptable yet solid, furrowed body covering.
Roundworms are very primitive living beings, having no respiratory or circulatory system of a host. They have an empty body with two openings at the closures. Be that as it may, the head isn't particular or recognizable to the unaided eye.
Roundworms reproduce sexually and can finish their life cycle in immature puppies, however as the little pupps immunity system develops (for the most part by a half-year-old enough), the larval phases of the roundworm will become captured and will encyst (become encased in a sore) in the puppy's muscles. They can stay encysted in the pooch's tissues for a considerable length of time or years.
