To answer this we need to remember how proteins are structured, the primary structure is just the polypeptide chain, secondary there is a certain folding level alpha-helix and folded beta-sheet, then is the tertiary structure that comes from a single polypeptide chain and is formed by secondary structures, finally, there is the quaternary structure where several polypeptide chains are involved as well as tertiary structures are folded together. Therefore taking this into consideration we can say that the correct answer is option two.
Answer:
Determine the MDC for the principal diagnosis
Explanation:
MS-DRGs are abbreviated as Medicare Severity Diagnosis Related Groups.
DRGs assignment :
- DRGs are th groups of diagnoses determined by the medicare to be related clinically and have similar resource consumption.
- Many different diagnoses exist within one DRG
- One DRG per hospitalization, assigned at discharge.
- Derived from all diagnoses and procedures listed.
- Groups the patients into categories that consume similar resources
- Measures case mix index
Coastal zones
Explanation:
Soft bottom intertidal habitats include seabed made up of fine grains of sediments, sand and mud. Depending upon the grain size of the sediment, depth of the seabed, temperature and light exposure, growth of bacteria or microalgae, the biodiversity of these habitats varies. A vast population of burrowing marine organisms like clams, crabs, snails, shrimps, skates, fluke, rays, sea cucumber etc are all found in this habitat. Commercial fishing is a main hazard in this habitat.
An estuary represents an area composed of water and wetland, where a freshwater body (like rivers, stream) meets an ocean. The unique feature of this habitat is the presence of salty brackish water which is a mixture of the salty ocean water and the fresh water.
Salt marsh is a coastal wetland that is mostly flooded and drained by the tidal salt water. The wetland is composed of mud and peat and hence is marshy. Tides often submerge the marshes and hence contain decomposed organic matter.
Mangroves are wetlands found along tropical areas with brackish waters. These help to prevent the ocean coastline. Halophytic plants and trees occupy these areas and form the typical mangrove forests in this habitat. Mangrove trees are unique with its prop root
Answer:
Nucleus
Explanation:
In a eukaryotic cell, these instructions are located in the nucleus.
Answer:
<u>3. exothermic, because the products are at a lower energy state in the reactants</u>
Explanation:
It is also because the average enthalpy is negative.
since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
