urea disposal

Explanation:

The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage.

The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.

The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine.

So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
