Suppose you are helping scientists conduct a study of a population of Kangaroo rats. The scientists initially capture 95 kangaroo rats from a field in Buttonwillow and tag all of them. After a month, they capture 110 kangaroo rats and count 25 tags. What is the estimated kangaroo rat population from a field in Buttonwillow?

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
