Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
Explanation:
The correct answer is "crossing over."
Cellular growth takes place under interphase, specifically under G1 phase of interphase wherein there is increase in cell proteins and structure. Duplication of chromosomes (or DNA synthesis) takes place under interphase, specifically under the S phase of interphase. In the S phase, there is also duplication of organelles. Crossing over takes place under prophase I of meiosis.
Answer:
to carry heavy load on the vehicle's outside
Explanation:
Aerodyanmic properties of a car refer to its interactions with moving air and the properties which govern smooth movement of the car through air. Aerodynamics of a car address the concerns like lowering noise emission, prevention of heavy load and avoiding the luggage dragging.
Now when there will be great load outside the car,the air will resist the movement of car more, so it will be difficult for the car to cut through the air. Moreover, when a car carries huge amount of load outside its body, the frictional force by aerodynamic drag increases greatly. This can badly effect the performance of high speed cars like sports cars but for other normal cars it poses less hazards.

The cell membrane is the structure that separates a cell and its environment. The cell membrane is an important part of the cell that provides an essential function to the cell protecting the cell and determining what is passed in and out of the cell.
