Mid ocean ridge
Explanation:
They are formed under water and there movement is generally up an out. I hope you get it right!
I think the correct answer would be the last option. People with one sickle cell allele are not likely to get malaria. This would be an example of genetic drift. It is one of the mechanism of evolution which involves the change in the frequency of an allele in a certain population due to the random sampling of the organisms. It is when a certain trait is being spread by chance rather by natural selection. Sickle cell is classified as an autosomal recessive disease that is caused by hemoglobin. It is a disease that is inherited depending on how the alleles are received. So, it can be inherited by chance.
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:
2.) Aegilops tauschii contributed two sets of chromosomes, and T. turgidum contributed four sets of chromosomes.
Explanation:
The mating of diploid and tetraploid species is one breeding method which has proven majorly satisfactory with the largest and most prominent mass producers of seedlings for uniform high-quality progeny, has been the mating of the tetraploid of good form with the free and prolific diploid.
The result yields a good progeny. This is due to the fact that the tetraploid parent influences twice as much as the diploid parent do. It's traits, form and color are more pronounced. This also implies that the diploid contributes two chromosomes and the tetraploid contributes four chromosomes. When hexaploid wheat was produced synthetically by He and co-workers, they mated diploid Aegilops tauschii, and the tetraploid species, T. turgidum. This implies that Aegilops tauschii contributed two chromosomes and T. turgidum contributes four chromosomes.
