Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.
Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome). The process takes the form of one DNA replication followed by two successive nuclear and cellular divisions (Meiosis I and Meiosis II). As in mitosis, meiosis is preceded by a process of DNA replication that converts each chromosome into two sister chromatids.

Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.
Answer:
<u>the forces of attraction are weak</u>
Explanation:
Particles are held together by forces of attraction between molecules e.g., covalent, van der waals and hydrogen bonds. Such type of forces are easily denatured by slight increase in temperature. The solid nature of the compound melts to liquid form. The size of the molecule determines the amount of intermolecular forces available. Smaller molecules have fewer intermolecular forces compared to larger ones thus the melting point is low. Larger molecules have more intermolecular forces that require more energy to break.
