The microscope is inexpensive and easy to use is an advantage of electron microscopy. High resolution images of both biological and non-biological specimens can be obtained using the electron microscopy (EM) technique. In order to fully understand the structure of tissues, cells, organelles, and macromolecular complexes, it is employed in biomedical research.

There are various kinds of electron microscopes, such as the scanning electron microscope (SEM), the transmission electron microscope (TEM), and the reflection electron microscope (REM.). Magnification and better resolution are possible thanks to the utilization of electrons as opposed to light waves, allowing for the analysis of structures that would otherwise be invisible.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer
larisa86 [58]
Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
            x + y + z = 140 meters


According to the proportion theorem,

\frac{x}{40} = \frac{y}{30}

Solving for x, using cross multiplication:

\frac{x}{1} = \frac{40y}{30}

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

 4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

Which of the following is a factor that, by itself, does not promote widespread changes in allele or genotype frequencies? a. Ne
defon

Answer:

A new mutation

Explanation:

A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.

However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.

denis23 [38]
Performance can be impaired by a fluid-related decrease in body weight of as little as 1 percent. Dehydration is assumed to be a major adverse effect associated with rapid loss of body mass and this impairs the level of performance in an individual.
