Pollen is one celled, or unicellular. It is used for reproduction in many types of plants. The bee is collecting nectar and, while doing that, is transferring the very tiny pollen grains The bee and the flowering plant are multicellular organisms, but they both have many things in common with the unicellular pollen What is one feature NOT shared by all three! All are made of one or more cells. The cells of each contain genetic material The cells of each contain exactly the same parts A cell membrane controls what goes in and out of the cells 9 Hierarchical Organisation SA PREP ITEST PREP PAX 1-877.816-0808 PHONE 1-877.377.953 Read Our Blog Meet Our Teachers Privacy Policy O USA Testprep LC 2030 A Rights Reserved

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
