<span>There are three types of hybrid reproductive barriers. The one described is called hybrid breakdown. In hybrid breakdown as the hybrid organisms continue to reproduce each sequential generation becomes less viable, healthy and loses it's ability to reproduce. The other two hybrid reproductive barriers are hybrid sterility and hybrid inviability. Hybrid sterility results in healthy organisms that can not reproduce at all since thy are sterile. Hybrid inviability results in organisms that are not strong enough to survive and often die while juveniles.</span>
Answer:
The correct answer would be Pp.
The genotype of one parent is PP. Thus, it will produce only one type of allele, that is, P.
Similarly, the genotype of another parent is pp. Thus, it will produce only one type of gamete, that is, p.
The cross would produce offspring with only one type of genotype, that is, heterozygous Pp.
The phenotype of all the offspring will be purple as it is a dominant trait.
Unregulated and uncontrolled cell growth is the most common simple definition of cancer. Because of the many types of cancers and a huge range of possible symptoms, treatments are also very diverse. Type of treatment also depends on cancer stage at diagnosis, and the patient's overall health. Some forms of treatment:
• Chemotherapy-usage of chemicals (medications) that target rapidly uncontrolled dividing cells,
• Hormone therapy
• Immunotherapy-usage of the medications that boost the immune system
• Radiation therapy-usage of radiation to kill the cancer cells
• Surgery
• New approaches such as stem cell therapy or personalized therapy.
The best vitamin to recommend in the scenario given above is VITAMIN B3, WHICH IS ALSO KNOWN AS RIBOFLAVIN.
John is suffering from ariboflavinosis, which is a deficiency disease that is due to inadequate intake of riboflavin and the disease is characterized by sores on the mouth.
Explanation:
This is because the atom that ’donate’ the electrons and the one that ‘accepts’ the electrons – to become ions – will share an electrostatic association and form an ionic bond. So in reality, the atoms are only transferring electrons between themselves rather than “losing and gaining” electrons. When the ionic bonds are broken, such as in chemical reactions, the atoms go back to neutral (regain their electrons) and form new associations with other atoms to form new compounds.
