Answer:
cohesion, large heat capacity, low density as a solid, and good solvent
Explanation:
Water is a good solvent and is important in dissolving some compounds and changing them into
liquid state.
Water has a large heat capacity which means it can absorb large amount of heat before drying up and this is important in the homeostatic process of plants and animals.
It has a low density as a solid which simply means its solid form isn’t denser and heavy compared to other solids.
It has good cohesive Forces which encourages surface tension. This surface tension prevents the breaking of substances under stress.

Answer:
Conduct a second survey
Explanation:
Mean age is the average age in a particular group of people. It is used in statistics to compare a group of people with another one.
The purpose of the mentioned survey was to compare the level of relationship satisfaction between married and non-married couples. For the survey to be valid, the average (mean) age in these two groups should be the same. People behave differently at different stages in their lives, some may be satisfied with their relationship at 23 and dissatisfied at 30. The age gap between the two groups here is to great to reach any plausible conclusions. You should conduct a second survey with the same or similar age groups.
Answer:
They wanted a route that was not only quicker, but safer and less rough. A passage that was easy to navigate and ensure the goods to trade would arrive at their destination and the ships would return with the exchanged goods and profits.
This data is called "secondary data".
An example for a usage of a secondary data is when a researcher takes up a data collected by someone else, for exam ple a large survey, and analyses this data to receive new insights from it - this is a fairly common practice. Often for example official government data is used by scientists
