116) The temperature at which all molecular motion stops is – a.-460Cb.-273Kc.0Kd.0C 117) A particular species of ladybug feeds exclusively on red flowers. During this process, the ladybugs pollinate the flowers and also mate. Over time, a mutation appears in the plant population that result in yellow flowers. Some of the ladybugs start to pollinate and mate on the yellow flowers. Eventually, the ladybugs that feed on red flowers and those that feed on yellow flowers can no longer mate with one another. What is the most likely explanation for this occurrence? 118) In a certain species of rose, color is determined by a single allele. The dominant allele, R, produces red flowers, and the recessive allele, r, produces white flowers. A scientist crosses a red rose with another red rose to produce the F1 generation of offspring. He then randomly selects two of the F1 generation and crosses them, resulting in the F2 generation. All of the F1 generation had red flowers. The F2 generation consisted of 75% red roses and 25% whiteroses.What were the genotypes of the two roses in the parent generation?
119) In humans, which organ is not part of the endocrine system? 120) A scientist believes that a particular species of algae, S. sponferus, is able to grow even when living deep underwater. However, he hypothesizes that this species may grow more slowly than algae in other environments due to the lack of sunlight at this depth. Which of thefollowing findings would not support the scientist’s hypothesis? a.Many other species of algae are able to live at depths of 1000 meters under the surface of the waterb.Laboratory experiments show that S. sponferus grows equally well under a wide range of light conditionsc.S. sponferus is found growing in abundance on the ocean’s surfaced.Some species of algae are discovered that do not need much light to grow 121) A man is on an airplane with a cabin pressure of 0.95 atm and a temperature of 22C. He empties a flexible 0.5L bottle and puts the cap back on. When he disembarks at the airport, where the pressure is 1 atm and the temperature is 24C, what will happen to the volume of his empty bottle?
