The correct option is A.
Multicellular organisms are made up of many different cells. Each type of cell perform a unique basic function which another type of cell can not perform. Cells are usually equipped to carry out their functions by their components, structures and sizes.
The 1st step is for energy to be converted to ATP
If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. <span>The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.</span>
<span>In a longitudinal wave, particle displacement is parallel to the direction of wave motion.!
Just remember Looong-itudinal , long = like a spring in a spring its compressions and the wave travels "thru,on the spring" so its parallel to the source/wavemotion.
the other to note is the last selection , perpendicular is transverse wave. So these 2 are the most common types that will appear :D
