Answer:
There was a release of immense heat within the bodies as they collided together as gravitational potential energy was converted into kinetic energy of the individual gas particles and then collisions between these particles converted this energy into heat.
Therefore, a massive amount of heat was released.
Answer:
The water will flow from the inside of the cell to the fluid outside the cell. This means that the solution would be <u>hypertonic</u>.
It will happen to the tubes that have a higher concentration of solutes in the fluid outside cells than inside the cells.
Explanation:
When a cell is in a hypotonic solution, it means that the concentration of solute in the solution is higher than the one in the cell. As a natural reaction, the cell tries to balance this difference. To do this, the water that is inside the cell flows to the outside. As a result, the concentration between the inside and the outside of the cell becomes equal or more equitable. Besides, the cell shrinks due to the loss of water.
Answer:
High altitude – as altitude increases, the availability of oxygen decreases, making the air thinner and drier. The dryness can cause the nose to bleed.
Answer:
See explanation
Explanation:
A catalyst refers to any substance that increases the rate of a chemical reaction. A catalyst does not affect the equilibrum position rather it enables the system to attain equilibrum faster.
Biochemical catalysts increase the rate of biochemical reactions in the body. They enable the body to carry out certain important functions that are necessary for life.
Answer:
Mechanical Isolation
A snail with a flat disc-like shell
will not be able to mate with a
snail having a conical shell.
The reproductive organs of
male bush babies do not
match with the reproductive
organs of females of other
bush baby species
Behavioral Isolation
The mating call of a cricket is not
recognized by a cricket of other
species.
The signals sent by a male firefly
are not recognized by the female
firefly of other species.
Explanation:
Mechanical isolation occurs in the scenario where two organisms are willing to mate but cannot do so due to the physical challenges. As in the case of snail a flat disk and a conical disk snail are willing to mate but physical barriers restrict them in doing so.
The same case is with the male and female bush babies where the difference in reproductive organs does not allow them to mate.
Behavioral isolation represents a scenario where two organisms are unaware of mating rituals, season, pattern or signals of each other and hence cannot mate.
For example – male and female cricket do not recognize the mating call of each other. Likewise male and female firefly is also not able to understand each other’s mating signal.
