<span>An electron microscope is very powerful and allows you to see very tiny, thin specimens.</span>

Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.

Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.

Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.  

Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern

al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.

In the water process what do clouds form as a result of?
nexus9112 [7]

Answer:

Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. ... That means some of the liquid water in the towel or bowl changed into an invisible gas called water vapor and drifted away into the atmosphere.

What is the phenotype of a plant with the genotype RR
vazorg [7]
To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:

R= tall stalk
r= short stalk

The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.

Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.

What do scientists hope to accomplish using recombinant DNA?
Ber [7]

The correct answer is: Replacement of defective genes with normal genes

Recombinant DNA molecules are made in laboratory by the methods of genetic recombination such as molecular cloning. The aim of these methods is to bring together genetic material from different sources, creating “combinations” that usually couldn’t be found in the genome. The process of recombination is possible because, DNA molecules from all organisms share the same chemical structure (nucleotides are same among different species, difference is only in the nucleotide sequence).
