The example for population density is "two jaguars per thousand hectares"
Explanation:
To known the population size per unit area we use population density. Or sometimes use it for volume. It is expressed in quantity or in the type. Mostly used for the living organisms, specifically humans. It's unit is expressed in square kilometers or may say in square mile. It is used for country, city, town and another territory. The negative relationship is found to affect the population density. It depends on the reproduction and survival.
Fat is less soluble in water compared to phospholipids.
This is because, fat is made up of three molecules of fatty acids which are not polar in nature at all, thus they mixed very poorly with water.
Phospholipids on the other hand has its molecules divided into two distinct regions, the head and the tail region. The head region is hydrophillic and it is polar in nature, that is, it mixes well with water. The tail region is made up of the fatty components and it is hydrophobic.
Because of this difference in structure, phospholipid will dissolve better in water.
Answer:
One reason is that there was too much pressure in the bottom of the ocean, from all the water pressing together.
