Answer:
D) Silent mutation on second codon, third amino acid changed from ILE to ASN.
Explanation:
Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]
On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
Answer: The answer is option D) phylum-class-order-family-species-genus
Explanation:
In taxonomy, living organisms are arranged from large to smaller categories. The complete arrangement as given by Carroleus Linnaeus is shown below
Kingdom --> phylum/division --> class --> order --> family --> genus --> species
He first split living things into a general category called KINGDOM.
- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).
- Each phylum or division is broken down into CLASSES.
- Each class is broken down into ORDERS
- Orders into FAMILIES,
- Families into GENUS
- Genus into SPECIES
Answer:
The ancestors of mammals diverged from ancient synapsids (reptiles).
Explanation:
The mammals have known to be evolved from a group of reptiles. These group of reptiles were known as synapsids. In fact, some scientists consider mammals as the only living synapsids. The close relativity between reptiles and mammals can hence be seen because they have common ancestors. The synapsids were known to inhabit the earth during the Permian Period.
The scientists, however, do not know from which reptiles exactly did the first mammals grow.
In asexual reproduction, one organism can produce other organisms. Asexual reproduction involves various kinds of cell division in which one organism produces one or more new organism that are identical to itself. Organisms reproduce asexually in many ways in prokaryotes, bacteria reproduce asexually by cell division. Some eukaryotes may also reproduce asexually by complex processes.
Una función es una relación en la que cada posible valor de entrada conduce exactamente a un valor de salida. Decimos "la salida es una función de la entrada". Los valores de entrada componen el dominio y los valores de salida componen el rango.
