Natural selection is the idea that individuals who are better adapted to their environment are more likely to reproduce and pass on their genes. The environment that many bacteria live in is the human body. How does natural selection work to produce drug-resistant bacteria?

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

cells spend most of their time in interphase

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.

answer: dna

because all cells have genes
