Paramecia feed on bacteria. Paramecia have 2 nuclei‚ 1 macronucleus and 1 micronucleus. Some have up to 80 micronuclei! The organism cannot survive without macronucleus and cannot reproduce without micronucleus. I used the 4x on the Parmecium caudatum to measure 11 cells they varied in length from 145.44-199.98um‚

Effect on Exercise (Arm Length to Body Height Proportion to Maximum Power) Aim: To investigate the effect on maximum power‚ when the proportion of arm length to body height is changed. Hypothesis I predict that the increase of proportion linking arm-span to body-height will increase the maximum power. Although the increase of arm-span also corresponds to the increase in weight‚ this will have minimal effect‚ (due to limitations). If the proportion is large‚ this will mean that the thrust

Recommendation and Conclusion Based on this analysis‚ our recommendation focuses on three main areas: 1) A Blending of Brands: AirAsia has established a great name and reputation‚ and should continue to add to its success by integrating the AirAsia X brand. This can be achieved by the “X” representing premium choices on long-haul flights. This will this ease brand confusion by having only one Air Asia brand with extra (X) options‚ and will present a strong united front. 2) Implement Long-Haul Flights

Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

Arc Length The definition of radian measure s = rθ The unit circle An angle of 1 radian Proof of the theorem IT IS CONVENTIONAL to let the letter s symbolize the length of an arc‚ which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally‚ "stretches under." Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π. π | = | C D | . |

pendulum’s period‚ depends only on the pendulum’s length and the value of gravity. In an experiment‚ an experimenter can easily manipulate a pendulum’s length. The value of gravity cannot be manipulated. The best way to find the gravity of a planet/moon using a pendulum would be to use the pendulum to find the time it takes to swing the length of a period. So we know two variables in the equation g=4π2L/(T2)‚ where g is gravity‚ L is the length of the pendulum‚ and T is the period of the pendulum

I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)
