Spelling, grammer etc?

Firstly, and most importantly, the word 'cuprum' isn't a word, at least not in latin or english, as far as I know, and I study latin. The word for copper in latin is '(h)enus'

Secondly, you need to at least act sure about what you're saying. Write with conviction, even if you don't have any. Don't say "never really discovered", either it was or it wasn't.

Thirdly, you need punctuation. After "certain point in time" add a comma. You also need a comma after pipes in the phrase "guns, pipes, and even blue fireworks." Plus, fireworks is one word. You need to turn this from one paragraph into at least two different ones.

Rephrase the whole section with the two sentences "in the bloodstream. But large amounts" etc. That can be turned into better sentences, or one sentence.

In the sentence "But large amounts" after 'but' add an 'in' and get rid of the comma after amounts. Also, you should change deathly to deadly, or something else. The sentence should look like this:

"But in large amounts copper can be poisonous or even deadly to organisims."

or:

"But, in large amounts, copper can be poisonous or even deadly to organisms."

You might also want to add an adjective describing the organisms.

With the next sentence, add 'the' between 'in' and 'water'.

Rephrase the last setence too- it doesn't really make sense,

Possibilities:

"The effect of too much copper is damage to gills, liver, kidneys, and the nervous systems of fish and other animals."

It's too long. you should probably change it into two sentences.

"This has many bad effects on land animals and fish. Some things that could happen are damage to the gills, liver, kidneys, and the nervous system."

I hope I helped.

Copper comes from the Latin word cuprum. Although it has been in existence for thousands of years, the time that it was discovered is still unknown. Copper has many uses in which it is involved in the production of bronze, watches, guns, pipes and even blue fire works. Other than that, this metal is an essential nutrient to all higher plants and animals whereby it can be found in the bloodstream of the latter.

However, large amounts of copper can be poisonous and might caused death to organisms. For instance, marine life can be damaged from too much copper in water. As a result, fish and marine creatures are affected due to damage of their gills, liver, kidneys, and nervous system.

hope this helps. :)

The word "Copper" is extracted form the Latin root " Cuprum ". There is no special date or time of invention of this metal. It has been a part of civilization since thousands of years. Copper is used in the production of Bronze, Watches, Guns, Pipes and even blue fireworks.Copper is an essential nutrient in few plants and animals. It is found in the bloodstream of animals. But, intake of copper in larger amounts can be poisonous and can cause death to organisms. Excess of copper content in the water can cause damage to marine life. It causes damage to the gills, liver, kidneys and the nervous system of fishes and other Marine beings.

I inserted some corrections within [].

Copper comes from the Latin word cuprum. [It was never really discovered at any certain point in time][The moment of its discovery is uncertain] but [it] is known to have been part of civilization for thousands of years. Copper can be [used for] [found in] many things like bronze, watches, guns, pipes and even blue fire works [firewords]. Copper is an essential nutrient to all higher plants and animals. In animals, it is found in the bloodstream. But [in] large amounts, copper can be poisonous or even [deathly][deadly] to organisms. ]It can also damage marine life from too much copper in water.][It is toxic to marine life at high concentrations.] The effect of this on fish and other creatures is damage to gills, liver, kidneys, and the nervous system.

Sounds good to me except I think a few changes should be made. Instead of never really discovered at any certain, it should read It was not discovered at any certain... a period after time. then, Copper is known to have been used in many things such as bronze...............Leave the But out. and in stead of deathly, use the word deadly.Marine life can be damaged by too much copper in the water.the rest is good.

Your writing is good. You should never start a sentence with "but".

You have a whole bunch of thoughts crammed into one paragraph. Separate the different thoughts in to paragraphs:

Discovery of copper and uses through the ages, copper in living organisms, copper's toxicity.

You can put your text into Word and see how it corrects the spelling and grammar. Word is not necessarily fail safe.

Not "deathly", DEADLY or (even better) FATAL. Fire works = Fireworks. Higher plants and animals? define HIGHER.

"Too much copper in THE water." Put in the "the." And say "an excess of copper."

Not "grammer"... GRAMMAR.

just some corrections - make sure you put them in!!!

u also spelled rephrase incorrectly....

too much copper in water can damage marine life

Yes. They don't pay concentration to the truly dilemma, the query or the field topic. The spellings might constantly move improper , what's there in it, one will have to get the that means, intelligently.

grammar.
