The correct answer is cohesion and adhesion.
The cohesion of the water means that the H₂0 molecules are attracted by other H₂O molecules (molecules of the same kind are attracted). Adhesion is the attraction of molecules of different kinds. <span>Water moving up a straw is an example of the motion of water against gravity which depends on the attraction between water molecules and the walls of the straw (adhesion), and also on the attraction between water molecules (cohesion).</span>
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
Explanation:
The main properties of water are its:
- polarity
- cohesion
- adhesion
- surface tension
- high specific heat
- evaporative cooling
Answer:
Phenotype is physical appearance of the individual while genotype is the genetic makeup of the individual.
Explanation:
Two parents having normal phenotype but effected individual is due to the parents may be Carrier for the particular deseis and the gene responsible for the desies may be in recessive form and the parents are not effected. The gene is not present in dominant form and can not show its effect but the parents are not effected and the daughter may be affected by certain desiese.
I have not researched into this area but I can think of a few explanations.
1) Food prices have decreased due to globalisation which has lead to an increase in portion sizes and overconsumption. Food prices are much cheaper these days as globalisation has allowed us to grow and produce food much cheaper in LICs (low income countries). This means Americans are more likely to consume more food as it is cheaper.
2) Fat is not the only cause of obesity: In the 1970s-1980s the popularity of low fat "health" foods skyrocketed (and has maintained popularity to this day). To compensate for the lower fat the amount of sugar was increased. Sugar is as bad or even worse than fat when it comes to causing obesity so replacing fat with it does not stop the rise of obesity.
This is a very interesting question and I could write many many more hypothetical answers so this is just scratching the surface.
Hope it helps.
