a. new source of fresh water <span>
Other choices are:
</span>
<span><span>b. less access to medicine </span>
<span>c. a higher birthrate </span>
d. a higher fertility rate
New source of fresh water </span>would most likely increase the carrying capacity for humans in a certain region. Water plays many important roles in the ecological and environmental systems, and also in humans. In cellular activities and organismic activities, water is used primarily.
For example,
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.<span> </span>

During mitosis, the <em />nuclear membrane breaks down and the duplicated chromosomes are separated and evenly distributed to opposite sides of the cell. Cytokinesis involves the division of the cytoplasm and the organelles that are contained within.
This describes the process of cell division. All of these events happen in the M phase of mitosis. The breaking down and fragmentation of the nuclear membrane to expose the genetic material is in the prophase. The next phase is the metaphase when the duplicated chromosomes align in a straight line (metaphase plate). Anaphase involves the separation of chromatids and by the time the chromatids reach the opposite side then the cell enters telophase. Lastly, cytokinesis involves restoration of the nuclear membrane, division of the cytoplasm, and production of two daughter cells.
Both mitosis and meiosis are a cell division process having various similarities and differences.
Similarities between the process of mitosis and meiosis include:
- Both the processes are cell division process.
- Both the processes occur in the nucleus of a cell.
- Both the processes result in the formation of daughter cells.
- The main phases are the same in both the processes
The differences between mitosis and meiosis include:
- As a result of mitosis, two daughter cells are formed. As a result of meiosis, four daughter cells are formed.
- The process of mitosis occurs in somatic cells whereas the process of meiosis occurs in reproductive cells.
- The daughter cells formed as a result of mitosis are the exact copies of parent cell. In the process of meiosis, genetic recombination occurs and hence the daughter cells are not exact copies of parent cells.

Double-stranded RNA-mediated interference (RNAi) is a simple and rapid method of silencing gene expression in a range of organisms. The silencing of a gene is a consequence of degradation of RNA into short RNAs that activate ribonucleases to target homologous mRNA.
