Answer:
The Endocrine System
Explanation:
Because a hormonal mechanism is created by the kidneys for the maintenance of blood pressure by stabilizing blood volume.
Answer:
Option (C)
Explanation:
Biodiversity usually refers to the different varieties of life forms that exist on earth. This includes the varieties in terms of ecosystem, and species and genetic changes.
This biodiversity is directly dependent on the region where there occurs a high amount of sunlight and precipitation. The factors such as latitude, climate, height, availability of resources are important for the growth and expansion of biodiversity. In these regions, the biogeochemical cycle also occurs rapidly, as the processes that are associated with it occur at a faster rate, thereby enhancing biodiversity.
Thus, the correct answer is option (C).
Koch's postulates are:
- Microorganism is found in all the infected organisms, but should not be present in healthy organisms.
- Microorganism can be isolated from an infected organism and cultured in lab.
- Lab cultured organism should cause disease in healthy person when injected.
- Microorganism needs to be isolated from the infected organism in step 3, the infected organism and the isolated microorganism should be checked with the case in step 1 and 2.
Some individuals contain alternate versions of specific genes (alleles) that make them resistant to particular diseases. for example, people with certain globin alleles are resistant to malaria, and some people cannot be infected with HIV because, genetically, they lack the co-receptors that the virus needs to enter cells. This will lead to the failure of Koch's 3rd postulate.
Answer:
In a monohybrid cross, both the alleles are expressed in the F2 generation without any blending. Thus, the law of segregation is based on the fact that each gamete contains only one allele. This law is based on four basic concepts: A gene exists in more than one form of an allele.
