Answer:

2. Hip bones

Explanation:

More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.

Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.

Jordan is working with a 50% stock concentration of Windex. She decides to add 500 µL of bacteria to a tube containing 1 mL of n
Lady bird [3.3K]

33% is the unknown concentration of the tube.

Explanation:

Concentration of stock of windex = 50%

concentration of bacteria = 500 microliter

nutrient broth = 1000 micro litre +500 microlitre of windex

concentration of bacteria is the volume of bacteria present in nutrient broth culture.

total volume in the tube is 1000

50% is the concentration of tube of bacteria and broth before adding windex.

After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.

33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.
