Ponds, lakes, streams and rivers are all part of what kind of ecosystem
kicyunya [14]

Marine ecosystems cover approximately 71% of the Earth's surface and contain approximately 97% of the planet's water. They generate 32% of the world's net primary production. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. Seawater has an average salinity of 35 parts per thousand(ppt) of water. Actual salinity varies among different marine ecosystems.

A classification of marine habitats.

Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides; in this figure it is termed the littoral zone. Other near-shore (neritic) zones can include estuaries, salt marshes, coral reefs, lagoons and mangrove swamps. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.

Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Fishes caught in marine ecosystems are the biggest source of commercial foods obtained from wild populations.

Environmental problems concerning marine ecosystems include unsustainable exploitation of marine resources (for example overfishing of certain species), marine pollution,climate change, and building on coastal areas.

It is possible to use molecular genetic techniques to characterize the T cells found in psoriasis plaques and compare them to th
babymother [125]

Answer:

According to what has been investigated the option that should be supported by more scientific evidence: In psoriasis plaques, there are fewer T-cell clones, but there are often a large number of T-cells representing only a small number of clones (this is called oligoclonal expansion).

Explanation:

Oligoclonal expansion does not occur only in this pathology, it also occurs in other recurrent diseases such as multiple sclerosis, this phenomenon is widely studied and little discovered in some aspects and is mainly based on both tcd4 and tcd8 and b lymphocytes.

In this case, the presence of ltcd4 in psoriasis is very versatile and depends on the patient's immune response, which is why more scientific evidence is needed on this topic, based mostly on meta-analyzes.
