Answer:
(A) Benthic- Benthic refers to the lowest or the bottom zone of the water body such as seas, and oceans. The organisms existing under such extreme pressure conditions are commonly known as benthic organisms. For example, corals and bivalves.
(B) Pelagic- Pelagic refers to the upper top portion of a water body, covering the open sea areas. The organisms existing in this region include dolphins and sharks.
(C) Sessile- Sessile refers to the property where an organism is stationary and cannot move freely from one place to another. These are known as sessile organisms such as coral polyps, Mussels.
(B) Mobile- refers to the property by which an organism can move freely in any direction it wants. For example, fishes, dolphins.
(E) Evisceration- It is a specific type of property where organisms can eject their internal organs in order to protect themselves from predators. for example, Sea cucumbers.
(F) Chitin- Chitin is a hard shell that is present in various organisms, forming its exoskeleton, for defense purposes. For example, arthropods.
surface evaporation will occur
where water is converted into gaseous state
when it reaches 100 c the it will boil and faster evaporation occurs
Answer;
-B3
Explanation;
Refrigerants are divided into two groups according to toxicity:
-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or equal to 400 ppm; and
-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.
They are also divided into three groups according to flammability:
-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101 kPa;
-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3 at 21°C and 101 kPa and a heat of combustion of less than 19 kJ/kg;
-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less than or equal to 0.10 kg/m3 at 21°C and 101 kPa or a heat of combustion greater than or equal to 19 kJ/kg.
-Therefore; the answer for the above question would be Class B and class 3.
That prokaryote is <span>Psychrophile, a coccus and a decomposer.
1)The prokaryote is</span> shaped like a ball or generally has a round shape so it's called a coccus (Cocci in plural). This is one out of three terms, that are used to name bacteria. The other ones are bacillus and spiral. For example, Staphylococcus aureus is a bacteria that has a round shape but it's formed by more that one ball, that together look like a bunch of grapes.
2) This organism lives deep under the water, so it's named as a psychrophile or cryophile. This means they can live and reproduction at extremely low temperatures(-20ºC), and some places with those temperatures are the polar regions and the deep sea.
3) This prokaryote consumes dead organisms so it's classified as a decomposer.
Decomposers are organisms that can break down dead or decaying organisms. The process is an essential part of the nutrient cycle and is important for recycling the organic matter that occupies space in the biosphere.
