This liquid substance most probably be a member of the group of lipids. Liquids which do not dissolve in water are called hydrophobic substances. Nonpolar substances exhibit this effect. Lipids are a class of large molecules or macromolecules which are hydrophobic. Lipids include cholesterol, fat, and phospholipids.

Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
Answer:
9600 cm/min
Explanation:
Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.
10 radians per second divided by 2π is the number of revolutions per second.
So multiply that times the circumference and that's the distance the point has traveled.
let the linear speed of the spot be v
therefore, v= 160×60= 9600 cm/min
I think it would be A. Helicase
