He 10 nm fiber and the 30 nm fiber are two chromatin structures that differ in width. which comparison between these two structures is false? -a solution of 10 nm fibers can be induced to form 30 nm fibers by addition of histone h1-linear dna is more heavily compacted in the 30 nm fiber-in the 30 nm fiber, more dna is associated with nucleosomes and the linker dna is shorter-formation of the 30 nm fiber requires the tail domains of the core histones-dna is more accessible to the enzymes that regulate its function in the 30 nm fiber

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

the answer is d. none of the above
