Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.
Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.
There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.
In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.
In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.
Answer:
We learned how to prepare the object, how to focus the object, and how to correctly put the microscope away safely. It taught me that you have to start with the smallest magnification on the microscope and then after you have the specimen lined up then you can turn the nose piece to a larger magnification to get a closer look on the specimen.

Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
b. coral reefs
c. rivers
d. ponds
B. coral reefs because marshes, rivers and ponds have nothing to do with the ocean ecosystem.
Answer:
Humans are its only known host
Explanation:
Humans are not the only known host for bacterium Francisella. For example, Francisella species such as Francisella tularensis uses many other organisms as its host.
Some of the non-human host organisms for Francisella tularensis are wild rabbits, most of the domestic and wild animals. The Francisella tularensis serve as causative agent of tularemia in these organisms which is a plague-like disease.
