They all have something in common
Explanation:
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. Dandelion seeds float away in the wind
Answer:
Physical Pollution
Explanation:
Physical Pollution is the type of pollution which occurs when small particles of soil are suspended in water. The small soil particles do not mix with the water but are rather suspended thus reducing the amount of light energy availed to micro-organisms in the water.
Physical pollution is the type of pollution that is caused by color change, suspended solids, temperature conditions or radioactivity.
Answer:
The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises in each generation. Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.
The reactions release chemical energy that the cells can use to power growth and other important cell processes
