In this activity, you'll open your non-dominant hand (the hand that you don't use for writing) and then squeeze it into a tight fist as quickly as you can for 100 seconds and write down the number of squeezes every 10 seconds. If you have

access to a ball, you can squeeze the ball with your non-dominant hand instead. How do you think the number of

squeezes you can perform will change over the course of the experiment? How many squeezes do you think you can

perform during the last 10 seconds of the experiment?

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
