<span>Meiosis consists of one round of DNA replication accompanied by two rounds of cell division.
Before meiosis starts, the cell </span><span>goes through an interphase period in which it grows, replicates its chromosomes to have enough material to divide for the daughter cells.
Unlike mitosis, meiosis has 2 cell division (meiosis
I and II). At the end of the first division, </span><span>each cell has half the number of chromosomes of the parent cell. At the end of the second division</span> there is separation of the sister chromatids
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
<span>Water heats up, changes to water vapor and evaporates, rises into the sky. It cools, condenses, turns back into liquid water forming clouds. Then it falls back to earth as precipitation and runs down hills or mountains during runoff and returns to lakes and oceans.
I think i`m not sure :)</span>
The answer is <span>Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.
Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides:
Disaccharide = monosaccharide + monosaccharide
Sucrose = glucose + fructose
Lactose = glucose + </span>galactose
Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
