Fur color in a population of guinea pigs varies greatly. What component of a strand of DNA is responsible for the genetic variations among the guinea pigs fur color? the number of chromosomes the organisms have. the number of chromosomes the organisms have. the sequence (order) of the sugar and phosphate that make up the backbone of the DNA strand. the sequence (order) of the sugar and phosphate that make up the backbone of the DNA strand. the sequence (order) of the nitrogenous base pairs that make up the organisms DNA. the sequence (order) of the nitrogenous base pairs that make up the organisms DNA. the strength of the weak hydrogen bonds that hold the nitrogenous bases together. the strength of the weak hydrogen bonds that hold the nitrogenous bases together.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
