***the molecular tools are:
Restriction enzymes
Restriction genes allow the synthesis of DNA-cleaving endonucleases at very specific sites to digest parasite DNA
-RNAse
* RNA A: specifically cleaves single-stranded RNAs, and releases residues of pyrimidine 3'-phosphates
* H RNA: cleaves DNA / RNA hybridization -digests RNA in an RNA-DNA complex. It is used to remove RNA after making a first strand of cDNA using reverse transcriptase.
-Alclaline phosphatase:
Alkaline phosphatases are active at alkaline pH. They make it possible to remove the phosphate group situated at 5 'of a DNA chain. They are extracted from bacteria or animal origin (intestines). They are used to prepare recombinant DNA.
-Kinase:
Kinases make it possible to fix a phosphate group in the presence of ATP.
-the enzymes copying the nucleic acids:
* DNA Polymerase (Taq, and the Klenow fragment) for example)
* inverted transcriptase.
* RNA polymerase
-Ligase
***Use of these techniques.
The biologist has a number of tools and methods for studying gene mutation. The analysis of the gene will make it possible to diagnose certain pathologies. Then, once the pathology is known, the doctor can establish an adequate treatment for the patient in order to treat it.
Sound production is also known as phonation, and involves the process of vibrations generated by a combination of respiration, the vocal organ and the vocal tract. The physical structures that birds use are highly similar to that of humans, and the sounds that is generated travels through respired air.
The correct answer would be D. beaks of finches
I chose this answer because in the Galapagos islands, the species of finches were forced to separate into several different environments, where there were different foods and plants. They lived in these environments for many years and eventually the beaks of these birds adapted to the environment around them. So the finches in one environment may have gotten longer beaks to eat fruits and get honey better, while one may have gotten a smaller but longer beak to gather and break nuts easier.
Hope this helps!
Answer:because water is very polar
Explanation:
Anthropomorphism: The attribution of human characteristics or behaviors to an animal, object, or a god. Personification: The attribution of a personal nature or human characteristics to something non-human, or the representation of an abstract quality in human form.
