Answer:
d. shrimp
Explanation:
shrimp is not fish it is a shellfish along with crabs, lobsters, and crayfish.
Answer:
Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.
Explanation:
Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.
The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>
Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.
This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.
Answer:
Biotic: <em>Food availability</em>
Abiotic: <em>Temperature</em>
Explanation:
There are two types of limiting factors for biodiversity: biotic and abiotic. Biotic refers to living things, for example, organisms that are an important food source. <u>Most animal life forms in the ocean highly depend on the availability of a food source</u>. If food is limited or scarce, the populations of a given species could face significant declines.
On the other hand, there are abiotic factors, which refer to factors that are not alive, such as physical factors. For instance, temperature and light. <u>For marine organisms, temperature is a critical factor.</u> Even an increase of 'only' 1 ºC could make a huge difference in the survival of a species as it could disrupt their ability to forage, hunt, or perform physiological processes, <em>e.g.</em> metabolism.
Therefore, <u>if we refer to a biotic factor, food availability is a limiting factor for most animal life in the open ocean, whereas, if the refer to an abiotic factor, temperature (and light) are limiting factors for pelagic life.</u>
