The affinity of hemoglobin for oxygen is less than its structural analog myoglobin. However, this does not affect hemoglobin's usefulness for the body; on the contrary, it allows hemoglobin to be a more efficient carrier than myoglobin. This is because hemoglobin can release oxygen more easily than can myoglobin. It is both important for oxygen to be carried to different areas and also to be released when needed. The higher affinity of a given protein for oxygen, the harder it will be for that protein to release oxygen when needed. Therefore, hemoglobin's lower affinity for oxygen serves it well because it allows hemoglobin to release oxygen more easily in the body.
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.

Answer:
1) OSCILLATING - group of communicating modules
2) Tympanometry is a test that is used to assess the state of the middle ear and eardrum mobility
3) Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye)
4) Electroretinography (ERG) is an eye test that measures retinal activity
5) Aphakia is the loss of the eye's lens due to surgical intervention
6) Cornea - front part of the eye
Explanation:
1) Oscillating - In many complex cellular processes, oscillations play a key role. They could appear as a group of communicating modules in the cell's collective dynamic behavior.
2) Tympanometry - Tympanometry is a test that is used to assess the state of the middle ear and eardrum mobility which is called tympanic membrane and conductive bones by generating changes in the ear canal's air pressure.
3) Orthoptic - Orthoptics is a specialty affiliated with the eyecare profession that main focus is on strabism (wandering eye), amblyopia (lazy eye) and eye movement disorders treatment and non-surgical management.
4) Electroretinography - Electroretinography (ERG) is an eye test that measures retinal activity (the part of the eye that detects light).
5) Aphakia - Aphakia is the loss of the eye's lens due to surgical intervention, such as a perforating wound or ulcer, or congenital defect in cataract surgery.
6 ) Cornea - The part cornea is the clear front of the eye containing the iris, pupil and anterior chamber.
Explanation:
What are the techniques of cutting flowers?
Custom-cutting the flower stem in open air and immediately placing it in the vase of water is usually fine. Cut all flowers and foliage about one inch from the bottom of a main stem. Make the slice at an angle of about 45 degrees. Cutting at an angle provides a larger exposed area for the uptake of water
