explain what safety measures you might take to avoid damaging the microscope, microscope slide, or a living specimen on your microscope stage

The equipments used in the science laboratories require proper handling and safety measures to help the students and researchers to prevent any kind of illness and injury.  

•The following are the safety tips to follow to avoid damaging the microscope, a living specimen on the microscope stage, or a microscope slide:  

•One should use the microscope with two hands and should wear proper lab clothing.  

•One should look at the specimen from the side, not via the eyepiece at the time of turning the low power objective as close as possible to the specimen at the time of the initiation of observations.  

•One should avoid the application of coarse adjustment knob at the time of using the high power objective.  

•One should prevent turning the fine adjustment knob more than a fourth turn to amend the focus at the time of using the high power objective.  

Thus, one should follow precautionary measures while handling microscope and its components.

Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;

1. Always carry the microscope with two hands

2. Do not touch the microscope lens

3. Clean and store properly after using

Explanation:

1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.

2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.

3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
