Answer:
If you double the speed of an object, the kinetic energy increases by four times. The word "kinetic" comes from the Greek word "kinesis" which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
Explanation:
The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
Correct answer: False
A primary source provide the first hand proof and the original information of the event, object, person or work.
Example: Research data, e.g. public opinion polls, speech
Secondary source is that source of information that is not performed or collected by the individual but it is taken from old information. It is updated by someone who is not participation in the event or the research.
Example: Library, ebook, reviews.
Phospholipids will form a bilayer in water because they contain hydrophobic (Water fearing.. in this cause water "hating") tails and hydrophilic heads (water loving). So they form a bilayer to remove the tails from water likewise, this satisfies the hydrophilic heads because they are still exposed to water.
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.
Answer:
There would be an over population of seals and less food for the species that eat what seals eat or for their prey it can be extinction, all of this can possibly causing extinction.
