Answers
Answer:
heyyy dear..
3=species
4=insecta
5=Herbarium
6=Walter Rosen
7=Physiological and biochemical
8=DNA and RNA
9=probiotic bacteria-Probiotic bacteria are those bacteria that are beneficial /helpful for other organisms. for example, lactobacillus it produces lactic acid for curd.
pathogenic bacteria- pathogenic bacteria are those bacteria that are harmful for other living organism & causes disease in host organism. For example, Streptococcus pnuemoniae this bacteria is responsible for disease like pnuemoniae.
10= They are sterile because they can't make sperm or eggs. They have trouble making sperm or eggs because their chromosomes don't match up well. And, to a lesser extent, because of their chromosome number. Mule is sterile in nature because it cannot produce male or female gametes (sperm or eggs).
11= The main defining characteristics of the Felidae family are: obligate carnivores need meat to survive 'hypercarnivores' mostly solitary, secretive and nocturnal.
12= Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
13= Because humans destroy their homes so they go to humans homes as a result. Think about it this way if squirrels live in a forest and the forest gets cut down then where are they going to go? They have no home to go back to since it was cut down so they're going to go into your backyard now because there's trees there for them to live in.
14= Zoos are smaller places providing protection to animals away from their natural environment. While wildlife sanctuaries protect and conserve wild animals in their natural habitats. They are spread in vast areas.
15= Yes there are very well known molecular methods by which we can do the identification and classification of organism.
Technique like DNA SEQUENCING( Maxum-gilbert etc), nano sequencing, Fingerprinting ( RAPD, Rep-PCR) Are widely used for the purpose.
16= The purpose today is to give every species a distinct name which will be recognised everywhere - because the common names of many species vary from country to country, or even from region to region within a country. Using Latin and Greek forms simply reflects the fact that Latin was the main language of science when the system was invented - so even when words from other languages are now used, they are given grammatical endings derived from those classical languages. Blakea attenboroughi is named for two scientists with English names...
