Decrease resource use methods might be used to decrease the rate of approach to carrying capacity by the developed world

Explanation:

Carrying capacity is the greatest quantity of people of a supplied species that an area's sources can support frequently without significantly spending or diminishing those resources. For communities which increase exponentially, growth begins gradually, starts a fast maturity phase and then straightens off when the carrying capacity for that species has been touched.

The proportion of the population then shifts somewhat above or below the carrying capacity. Reproductive lag time may produce the population to exceed the carrying capacity temporarily. The carrying capacity may be reduced by resource leveling and disgrace during an overshoot period or spread through technological and social changes.

28. Answer: All mutations do not affect the organisms due to the following reasons:-

1. The DNA consists of both coding and non coding regions. The coding regions are known as exons and non coding regions are called as introns. The non coding regions do not make up the protein. Thus, if the mutations occur in non coding regions they do not affect the organism.

2. There are some mutations that result in the change of the codon but the new codon formed codes for the same amino as the previous one. This is possible because of the degeneracy of genetic code. For eg, AAA codes for lysine, however if the mutation changes this code to AAU then this also codes for lysine. Such mutations are called as silent mutations.

3. There are some mutations which result in the change in amino acid however the new amino acid formed is similar to the previous one in its properties for e.g leucine and isoleucine. Such mutations are called as neutral mutations and they do not affect the organism

29. Answer: 1. The process of mitosis results in the formation of two diploid cells whereas meiosis results in the formation of 4 haploid cells.

2. The process of mitosis takes place to produce copies of the body cells whereas the process of meiosis takes place to produce the gametes.

Explanation:-

Mitosis is a process in which a cell undergoes a single round of division to produce two identical copies of itself . It occurs in 4 phases Prophase, metaphase, anaphase and telophase. This process occurs in the body cells.

Meiosis is a process in which a cell undergoes two rounds of cell division to produce 4 copies of haploid cells from a single diploid cell. This process takes place for the formation of gametes.

29. Answer:

Pros

1. Genetic engineering helps us to tackle several diseases. There are many diseases which are caused due to genetic mutations. Genetic engineering helps us to rectify these mutations and hence combat such diseases.

2. Genetic engineering helps us to produce new foods which can withstand adverse conditions such as high/low temperatures, low rainfall, are disease and pest resistant etc. This, genetic engineering helps to significantly improve crop production.

Cons

1. Genetic engineering leads to a decrease in genetic diversity.

2. It can lead to a decrease in the nutritional value of food as genetic engineering often causes an accelerated growth of animals and hence, the nutritional valie of poultry foods is compromised.

An objects position is always defined relative to a reference point. If the object changes position, its motion can be described

Orlov [11]

The position of the diver is described as "below a certain point"; therefore, the reference point must be above the diver. For a diver in the middle of his dive, the bottom of the pool, the other swimmers and the far side of the swimming pool are likely to be below the diver, or at level with the diver at most. Out of the options, the only point of reference that is likely to be above the diver is B. the diving board.
