The lateral line system provides tactile sense organs ( that is from cyclostome fishes to amphibians or the aquatic vertebrates) with a sense of distant touch, enabling these animals to sense objects that reflect pressure waves and low-frequency vibration. This system made up of multiple of neuromasts.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
1) Diffusion and osmosis
the diffusion of water through a semipermeable membrane is osmosis and the movement of particles from regions of higher density to regions of lower density is diffusion
2)The passive transport does not require energy and the active transport does ,this is what makes them different
3)Endocytosis is a process for moving items that are outside of the cell into the cytoplasm of the cell. Exocytosis is a process for moving items from the cytoplasm of the cell to the outside.
Answer:
A trait is most likely to exhibit continuous variation if it is controlled by <em>many gene loci, each with several possible alleles.</em>
Sexual Reproductions (i.e. Meiosis)
In Meiosis you have a crossing over stage in prophase I, which will result in the exchange of genetic material + the random assortment at metaphase 1 and 2 increases the variety.
There is approximately 10 billion different ways that a child can look from a mixture of the paternal and maternal genes due to all the random events that happen in meiosis/ sexual reproduction.
