I am more of a chemistry person, but my best answer is the double-helix structure. The DNA rotate around a central point allowing it to keep a constant distance
Answer:
The correct answer will be option- Clinical examination
Explanation:
Clinical examination is performed by the medical practitioner in which the practitioner examines the patient for a medical condition based on the physical condition of the patient.
The examination involves the three steps: a history of the patient, examination of the symptoms based on the medical reports and the possible explanation of for the cause.
Since in the given question, the dietician after noticing the physical health assessed the nutrition therefore the doctor is performing the clinical examination.
Answer:
Homologous characters
Explanation:
Homologous character is usually defined as those set of characters that are observed in various organisms and are similar to one another. It is because these organisms have obtained these characters from a common ancestor, having that same distinct characters.
The evolution that occurs in this type of organisms are commonly known as the homologous evolution, where the similarities between the organisms are found in terms of physiology, structure and/or other development, depending upon their common ancestors.
There are several specific characteristics for procaryote and eucaryote:
- Procaryotes has a cell wall, in addition to the cell membrane.
- procaryotes has chromatin in the cytoplasm, they do not have a nucleus.
- Procaryotes are small cells visible only at the microscope with x100 objective.
About the eucaryotic cells:
- Eucaryotes have mitochondria,
- Eucaryotes have endoplasmic reticulum
- Eucaryotes have a nucleus with DNA chromatin and nucleoli inside it.
- Eucaryotes are visible in the microscope x40
Answer:
The correct answer is "Orthologs are homologs found in the same species".
Explanation:
Orthologs, or orthologous genes, are defined as genes found in different species that evolved from a common ancestry. Therefore, It is false to affirm that orthologs are homologs found in the same species. Orthologous genes have the same function and often share common nucleotide sequences, however, they must be found in different species to be considered orthologs.
