Answer:
B. very high genetic variation
Explanation:
Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.
This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.
The correct answer is C. The right side of the heart delivers deoxygenated blood (from vena cava) to the lungs (via pulmonary artery)
Answer:
This is technology.
Explanation:
Generally both science and technology are instrumental to emergence of developed humanity and the environment.Why science is concerned with the emergence of knowledge,the manoeuvre and the practical application of the knowledge for innovations to change and improve the world around is called Technology.
The application of technology for improvement of humanity has wide application.From Healthcare in genetic engineering,Biomedical sciences, telemedcine,robotic surgery,to Agriculture to boost food production,cloning of crops and animals and production of pest and herbicide resistant products.
In construction for roads,and building of houses,fitted with AC and FAN for maximum comfort
Besides the application in field of engineering for power generation in petroleum, communication, entertainment,printing,warfare and transportation are few of other means where technology has improved humanity
