Compare and contrast a compound light microscope and transmission electron microscope be sure to discuss the structure and opera
Ainat [17]
Time for microscopes 101. There are two major types of microscopes; light and electron. In a light microscope the image if seen by refracting light through 2 or more lenses which result in a magnified image of the specimen being viewed. However there are limits to the ability to view these and they are not powerful enough to view very small object. An electron microscope which was referred to in the question works by cutting the specimen to be viewed into a very small piece and then bombarding it with electrons which result in a much clearer and more magnified viewing. HOWEVER, Electron microscopes do not work on living things while regular light microscopes do. Also, due to way how electron microscopes are made they are not common in everyday laboratories and are very expensive to buy.  comment below if you need anything else

Two different groups of scientists studying a rare trait in ground squirrels report very different heritabilities. What factors
iren2701 [21]

Answer:

It is a trait highly influenced by environmental factors (i.e., it has low heritability)

Explanation:

In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.
