Answer:

C) parfocal.

Explanation:

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.

A microscope is said to be parfocal if its lense is binocular and they can both be in focus.

Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.

What is RFLP? What are some of the limitations of this technique?
bearhunter [10]
In molecular biology, restriction fragment length polymorphism, orRFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a differencebetween samples of homologous DNAmolecules from differing locations ofrestriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated. InRFLP analysis, the DNA sample is broken into pieces and (digested) byrestriction enzymes and the resultingrestriction fragments are separated according to their lengths by gel electrophoresis. Although now largely obsolete due to the rise of inexpensive DNA sequencing technologies, RFLP analysis was the first DNA profilingtechnique inexpensive enough to see widespread application. RFLP analysis was an important tool in genome mapping, localization of genes forgenetic disorders, determination of riskfor disease, and paternity testing.

Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the
BlackZzzverrR [31]

Explanation:

In the given question, the graph and table have not been provided either they are found anywhere, therefore, the question has been answered on previous knowledge.

The species of Earth can adapt to their environment but adaptation in organisms can take a long time that is thousands to Lakh of years. But the rise in temperature is observed constantly past 200 years.

The species living in the tropics, equator and Poles are already adjusted for their thermal limit. If the average temperature of the planet will increase by 1°C then the number of individuals in the population will decrease. As the number of individuals will decrease, the number of population of species will decrease.

Due to this declination, the number of species can become extinct and therefore the process of increase in temperature and number of species that become extinct can be co-related.
