Answer:
List three ways of reducing friction. 1.Polishing the rough surface. 2.Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and 3.allow smooth movement as rolling friction is less than sliding friction.
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
Answer:
The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.
It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.
The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.
The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.
Consequently, the genetic diversity would also decrease.
<span>The proteins of the electron transport chain are located in the inner membrane of the mitochondria.
Electrons are passed from one protein of the transport chain to another in a series of redox reactions, making the proton gradient which is then used to make ATP.</span>
