We used new tags for the population estimate a year later. If we assume the tags stay on well over the year, what changes the pr

oportion of the old marked tags in the population and make the use of new tags more accurate? (Hint: look back at the assumptions made by the mark and recapture method).

<h2>Mark and recapture method</h2>

Explanation:

Mark and recapture is a technique to measure the size of a population before fishing and hunting season;commonly used by fish and wildlife managers

  • It involves the marking of number of individuals in a natural population,returning them to that population followed by recapturing some of those as a basis for estimating the size of the population at the time of marking and release
  • Population size can be estimated as(N)=M*T/R

here,M=initially marked;T=total in sample second;R=marked recaptures

There are certain assumptions to this method

  • Population is assumed to be closed which means no new individuals were born or immigrated into the population and none died or emigrated from the population
  • The chance for each individual in the population to be caught are equal and constant for both the  initial marking period and the recapture period
  • One of the assumption of this method is that sufficient time must be given between the initial marking period and recapture period for all marked individuals but time period should not be very long
  • Animals do not lose their mark

The tags in the given question were estimated a year there is a chance that old marked tags population might have died or emigrated(the longer the time interval the greater the chance) and hence it becomes an "open" population which violates the first law

If proportion of population changes then marked recapture method formula won't turn out be applicable

6. Cell membranes are primarily composed of a double layer of phospholipids. Why are phospholipids particularly
Andrews [41]

Answer:

B i hope this help

Explanation:

The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.

The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.

Water is warmed by the sun and
IceJOKER [234]

Answer: The water is warmed up by the sun and then it evaporates into the atmosphere. The sunlight warms the water by its heat.

Water is then cooled down and condensation takes place.

The water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

Water and nutrients that are not recycled on earth are stored in the form of reservoirs.
