The correct answer is "transmission electron microscope".

The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.

Attached is a sample picture of a transmission electron microscope image of a mitochondria.

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #
777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.  

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,  

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:  

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.  

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate  

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.

A ____________________ reaction is a severe response to an allergen, also known as anaphylaxis.
rjkz [21]

Anaphylaxis, also called allergic or anaphylactic shock, is a sudden, severe and life-threatening allergic reaction that involves the whole body. The reaction is marked by constriction of the airways, leading to difficulty breathing.

Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. An allergen is a substance that can cause an allergic reaction.

Anaphylactic shock is a rare but severe allergic reaction that can be deadly if you don't treat it right away. It's most often caused by an allergy to food, insect bites, or certain medications. A shot of a drug called epinephrine is needed immediately.
