If more genes for less arm hair are passed on more frequently after several generations will people have more or less arm hair?

That depends

Explanation:

Just because it says more frequently does not mean that the gene will be in every person's genetics. Some will have less arm hair, others more, or if it is a co-dominate gene then some will have an average amount. Now with that being said, just because someone may not express the phenotype of that particular gene does not mean that they do not carry that gene within their gene pool.  

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

not too sure but maybe in the hot springs.
