Answer: monosaccharides are simple sugars made up of only a single sugar molecule. Disaccharides are sugars made up of two sugar molecules linked together by a glycosidic bond while polysaccharides are complex sugars made up of many sugar molecules linked together by glycosidic bonds.
Explanation: Examples of monosaccharides are glucose, fructose, and galactose, while examples of disaccharide sugars include maltose, lactose and sucrose. Examples of polysaccharides include glycogen
and starch.
Answer:
sexual selection
natural selection
Explanation:
Natural selection is an evolutionary mechanism (changes the allele frequency) by favouring traits that are advantageous among others because they increase the survival and reproduction. In the example above, mosquitofish that live in the predator-rich ponds devoloped a trait that help them survive (swimming in short, fast bursts). This adaptation to environment is favourable by natural selection.
Sexual selection refers to the female mosquitofish and the fact that they choose their males (with better reproductive success).
Answer:
450 kilocalories.
Explanation:
Since only 1/10th of the energy that an organism consumes is passed onto the next level of the pyramid, that would mean only 500/10 = 50 kilocalories are passed on, and the remaining 500 - 50 = 450 kilocalories are used up.

You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plant receives pure water. After a two-week period, the height is measured. i think the indepent variable is sunflower ... variable is height measured and the control variable is the fourth plant.
