Answer and Explanation:
When there is limitation to resurces, there are behavioural activities that organisms perform like clustering, coiling, burrowing, migration, hibernation and aestivation.
Migration is seen in many homoitherms where there is movement over long distances to avoid unfavourable climatic factors and food shortage. During cold weather, large mammals survive by hibernating. They go into deep sleep and metabolic rate falls to the minimum required for maintaining the vital activities of the cells.
High shelf life apple and disease free banana are the two fruits that are being engineered to be healthier.
The yield, production and nutrition value of food can be improved by employing genetic engineering in the food production. This will solve the problem of food in countries where resources are scarce.
Explanation:
Genetic engineering is the process in which genes are altered or introduced in a particular organism or plant to create a useful trait.
The genetically modified foods have many advantages as no use of pesticides, long shelf life, high nutritious value and high yield.
The two fruits are:
Arctic apples are genetically modified so that they do not get brown after slicing. This healthier version of apple is a big step in preventing food wastage.
Banana plantations were suffering due to a disease fusarium wilt but GMO have resolved the issue and prevented the disease and increase its production.
The people of less privilege countries who continuously face famine and malnutrition can solve their food problem by using GM techniques. The yield and nutrition value can be increased manifold in the crops. Besides the crops would made to get ready in less resources to overcome famine conditions.
Each human cell has 46 chromosomes. all dna is organized into two pairs of 23 chromosomes.
