Chapter 21, Problem 1SQ
Summary Introduction
Concept introduction: Protists are eukaryotes and the interior of some freshwater protists like the euglena is saltier than its freshwater habitat. Due to this, the water will tend to diffuse into the cell of protists. Excess of water will cause the cell to burst. However, the contractile vacuole present in the cell will help to maintain the water concentration in the cell.

Reports that it laid eggs created much confusion. To modem biologists, a platypus is clearly a mammal. It has fur and the females produce milk.

Why do you think modem biologists can more easily accept that a mammal can have some reptilelike traits than scientists who were considering this animal in the late 1700s?arrow_forwardThe ___________________ of an egg serves as an embryos water supply while the ____________ provides a structure for gas exchange.
