Answer:
For the production of food for animals.
Explanation:
365,000 acres of land were needed for the production of feed for animals in order to produce beef. Feed such as grasses, berseem, shaftal and maize etc are given to animals because these plants has high protein content which is necessary for the production of meat in animals. If proper feed is not provided to animals so they becomes weak and low in meat which will not fulfill the beef need of a country so proper feed is necessary for the production of high amount of beef.
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
Answer:
DNA
Explanation:
Experiments such as the one by Frederick Griffith in 1928 showed that DNA is the hereditary molecule. How showed that virulent bacterial species could transfer DNA to avirulent species and make them virulent too. This means that DNA determines the characteristic of the individual and can be passed down or across generations.
