In the field of histopathology, the tissues to be observed under the microscope are cut in very thin slices. The thin slices make the tissue transparent, and thus, it becomes easier to observe the internal structures and accurately diagnose a disease. The tissues slices cut for the observation are generally not more than 3 micro meters in their thickness.
Hence, the answer is 'to make the tissues transparent and easier to observe'.
Answer:
Nichrome is usually used as the rod to heat water using electricity. It is an example of Nickel and belongs to the element Nickel in the periodic table.
Explanation:
My answer is from google but i hope this help
The right answers are mentioned in the picture.
A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters for Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Hello!
The answer is A. Analysis of DNA sequences
Explanation:
Classification:
Classification is the assortment or arrangement of living organisms into groups on the basis of their similarities. These groups into which organisms are classified are called taxonomic groups or taxon.
- Before the 1960s, scientists solely relied on phenotypic or physical characteristics of organisms to classify them into related taxonomic groups.
- Modern DNA sequencing methods are capable of revealing similarities and differences between organisms on the level of genes or DNA sequences. Therefore, DNA sequence analysis is the most accurate method for classification.
- Closely related organisms have specific genes with the same DNA sequence. These sequences, known as conserved sequences, can be found universally in all species of a particular organism. For example, in bacteria, a DNA sequence known as the 16s RNA is conserved in related species. 16s RNA analysis is widely used to identify and classify bacteria.
- Behaviors, body structure, habitat and food choices are all phenotypic characters that do not provide definite evidence of evolutionary relationship.
- Different species can have the same habitat, behavior, anatomy and morphology.
