The black-footed ferret is a highly specialized predator that depends on prairie dogs for survival. Prairie dogs make up more than 90% of the black-footed ferret’s diet, and prairie dog burrows provide ferrets with dens to raise their young, as well as a means to escape from predators and harsh weather. Ferret habitat largely coincided with the habitats of the black-tailed prairie dog (C. ludovicianus), Gunnison’s prairie dog (C. gunnisoni), and the white-tailed prairie dog (C. leucurus). Despite significant recovery successes over the last decade, the black-footed ferret remains one of the most endangered animals in the world. Consider the status of the black-footed ferret. What is the MOST logical contributing factor to its endangered status?

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

You are making a solution of calcium chloride dissolved in water. you add solid, stir, and it dissolves. you add just a spatula tip full, stir, and the solid does not dissolve. how could you describe the solutions before and after adding the spatula tip amount

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?
